The choice of casters should be good for mobility

About the flexibility of the casters.

The castors should be flexible, easy and durable, and their rotating parts (bracket turning, wheel rolling) should be made of materials with a low coefficient of friction or accessories assembled after special treatment (e.g. ball bearings or quenching).

The greater the eccentricity of the bracket, the more flexible the steering is, but the load-bearing capacity is relatively reduced.

The larger the diameter of the wheels, the less effort is required and the ground is better protected. The wheels rotate slowly compared to small wheels, which are not easy to heat and deform, and are more durable. If the installation height allows, choose wheels with a large diameter as much as possible.

Eccentricity refers to the distance between the steering axis of the bracket and the axis of rotation of the single wheel.

Xiangrong casters quality can.

The use of casters is to reduce labor intensity and improve work efficiency. According to the method, conditions and requirements of the application (convenience, labor-saving, durability), choose the right castor for your use.

Load-bearing weight: Load-bearing weight is calculated t=e+z m

t = load weight of each caster.

e = weight of the means of transport.

z = the weight of the moving object.

m = the number of wheels that can be effectively carried (the factors of uneven distribution of position and weight should be taken into account).

The effective bearing quantity of casters (m) is shown in the following figure:

When choosing a heavy weight, it is calculated according to the load-bearing weight of the caster at the maximum support point. The specific support points of the casters are shown in the following figure (P2 is the heaviest support point).

Traditional Flexibility:

1. The caster should be flexible, easy and durable, and its rotating parts (tripod rotation, wheel rolling) should be made of materials with small friction coefficient or accessories assembled after special process treatment (such as ball bearings or quenching treatment).

2. The larger the eccentricity of the tripod, the more flexible the steering is, but the bearing capacity is reduced accordingly.

3. The larger the diameter of the wheel, the more labor-saving it is to push, and it can better protect the ground. The wheels rotate slowly compared to small wheels, which are not easy to heat and deform, and are more durable. Choose wheels with large diameters as much as possible if the installation height allows.

Moving speed: caster speed requirements: in a normal temperature environment, on a flat ground, not higher than the walking speed of kilometers per hour, and a certain state of restless work.

Use environment: When selecting, the special environment of ground materials, obstacles, and residues (such as iron filings, high temperature, low temperature, high acidity, alkaline, oil and chemical solvents, and places requiring antistatic) should be considered. For use in special environments, casters made of special materials should be chosen.

Installation Notes:

Flat bottom movable casters: the mounting surface must be flat, hard and not loose.

Directional casters: Both wheels must be oriented in the same direction and remain parallel.

Screw casters: must be equipped with spring gaskets to prevent loosening.

Understanding the correct name of the caster is conducive to the newcomer to increase the common sense of the caster, which is conducive to your accurate order and improve work efficiency.

Choose the size: the larger the diameter of the caster, the more labor-saving the push, the better the obstacle ability, because the caster was first industrialized in the West at the end of the 19th century, so the caster is generally expressed in inches, such as China's supermarket trolleys mostly use 5-inch and 4-inch casters. At present, the popular caster size on the market is from 1 inch to 10 inches, and the commonly used sizes are 2 inches, inches, 3 inches, inches, 4 inches, 5 inches, 6 inches, 8 inches, 10 inches, etc., which generally need to be promoted, such as supermarket shopping carts, logistics trolleys, tool carts, etc., using 4 6 inch casters is better.

However, if the caster diameter is too large, the center of gravity of the equipment will rise, and the cost will increase, so it is necessary to consider comprehensively.

Installation method: Generally, screw rods, plug rods, expansion rubber sleeves, etc. can be used for medium and light loads, and bottom plates can be used for heavy loads, or directly welded to the equipment. Generally, large companies have a variety of installation methods.

Brake: Functionally, there are brake wheels, brake brackets universal, the two brakes are double brakes, as well as tread brakes, positive brakes, side brakes, etc., specifically contact the caster factory.

The arrangement of casters on the equipment: the arrangement is different, which not only affects the cost, but also greatly differentizes the feeling of pushing!

Bracket selection: divided into directional and universal, the material is generally carbon steel, can be used for various electroplating, such as galvanization, copper plating, nickel plating, chrome plating, spraying, etc., there are also stainless steel.

Look at the load-bearing: For casters of the same diameter, general manufacturers will produce several series for different load-bearing, such as light, medium, medium, etc., by making the wheels and brackets have different thicknesses or materials. When calculating the load of a single caster, a certain insurance factor should be given, and when the ground is relatively flat, the load of a single caster (the total weight of the equipment and the number of casters installed with the insurance factor); If the ground is uneven, the algorithm is, the load of a single caster The total weight of the equipment is 3, because no matter what kind of non-flat ground, there are always at least three wheels to support the equipment at the same time, this algorithm is equal to increasing the insurance factor, more reliable, preventing insufficient load-bearing, resulting in a greatly reduced caster life or causing an accident.

Wheel material: This is very important, generally there are PU, TPR, PP, rubber, nylon, etc., as for the applicable temperature, surface hardness, ground environment, etc.

Industrial casters: industrial wheels, divided into industrial rubber wheels, industrial rubber and plastic wheels, industrial PU wheels, etc., light industrial wheels, heavy industrial wheels, etc.

In terms of the manufacturers we contact, the simplest is divided into: small light casters, light casters, medium casters, heavy casters, super heavy casters, and other casters. Subdivided by its function: directional, gimbal, flat top, screw, plug rod, hole top, single brake, double brake, side brake, etc.

How to divide casters according to their useCaster is divided into civil caster, industrial caster, etc. according to use; According to the load, it is divided into light casters, medium casters, heavy casters, extra-heavy casters and special casters; According to the function, it is divided into universal casters, directional casters, screw casters, brake casters (double brake casters, eagle frame casters), shock-absorbing casters, etc.; According to the material, it can be divided into conductive casters, iron core casters, plastic casters, stainless steel casters, high-temperature resistant casters, polyurethane casters, nylon casters, rubber casters, all-iron casters, etc. According to the bearing, it is divided into bearing casters, needle rollers, etc.

Caster mainly refers to a kind of caster product used in factories or mechanical equipment, it can be used as a single wheel made of high-grade imported reinforced nylon (PA6), super polyurethane and rubber, and the product as a whole has high impact resistance and strength. The metal parts of the bracket are made of high-quality steel plate with galvanized or chrome plating anti-corrosion treatment, and precision ball bearings are installed with integrated injection molding. There are a lot of different factors that determine the choice of industrial caster, and the key is the best one for your use.

Here are a few of the most important considerations.

Each wheel adapts to a different working environment, and the best one is selected to adapt to the special environment. For example, traditional rubber is not resistant to acid oils and chemicals, if you want to adapt to different special environments, Nobel Hardware high-tech polyurethane rubber wheels, plastic wheels, modified bakelite rubber wheels and steel wheels are a good choice. The larger the wheel, the less effort it can turn, the ball bearing can carry heavier loads, and the ball bearing rotates more flexibly but carries less load.

There are many types of casters in Huiyi casters, you can ask them about the factory.

Wheel material selection for heavy-duty casters.

Heavy-duty casters are used for the movement of heavy equipment, so the wheels of heavy-duty casters are generally single-wheeled with hard tread. Such as nylon wheels, cast iron wheels, forged steel wheels, hard rubber wheels, polyurethane wheels, and phenolic resin wheels are ideal choices. Among them, forged steel wheels and polyurethane caster wheels are especially suitable for wheels matched with extra-heavy casters.

Wheel diameter selection for heavy-duty casters.

According to the principle that the larger the diameter of the wheel, the more flexible the rotation, the common specifications are 4-inch casters, 5-inch casters, 6-inch casters, 8-inch casters, 10-inch casters, 12-inch casters, and extra-heavy casters can use 16-inch and 18-inch wheels. At present, the 12 ton extra-heavy casters we produce are twin wheel casters with a diameter of 400mm and a wheel width of 125mm. Of course, it is also possible to customize special specifications for heavy duty, for example, low center of gravity heavy duty casters, the smallest 2-inch casters, can also bear more than 360kg.

The choice of heavy-duty caster manufacturers.

At present, there are many domestic manufacturers of casters, good and bad, therefore, users should purposefully choose heavy-duty caster manufacturers, and can not blindly pursue low, so as not to cause damage to the loaded products and unnecessary property losses because of casters. Choose a professional heavy duty caster manufacturer, users can refer to the following points::

1. Regular heavy-duty caster manufacturers can generally provide drawings and other relevant necessary technical parameters;

2. Regular heavy-duty caster manufacturers should have professional testing equipment, including caster walking test, load test and other professional caster testing equipment, otherwise, the load requirements of casters cannot be judged.

Classification of casters.

Categorize by whether to turn or not.

It is divided into directional casters and non-directional casters (i.e., universal casters).

Directional casters do not have a rotating structure and cannot be rotated; The structure of the universal casters allows for 360 degree rotation.

Classification by application industry.

It is mainly divided into medical casters, industrial casters, supermarket casters, furniture casters, etc.

Medical casters are special casters for light operation, flexible steering, high elasticity, special ultra-quiet, wear-resistant, anti-winding and chemical corrosion resistance to meet the requirements of hospitals.

Industrial casters mainly refer to a kind of caster products used in factories or mechanical equipment, which can be used as a single wheel made of high-grade imported reinforced nylon (PA6), super polyurethane and rubber, and the overall product has high impact resistance and strength.

Supermarket casters are specially developed to meet the needs of moving supermarket shelves and the need for lightweight and flexible shopping carts.

Furniture casters are mainly a type of special casters produced to meet the needs of furniture with low center of gravity and high load.

Classified according to the material of the casters.

It is mainly divided into super artificial rubber casters, polyurethane casters, plastic casters, nylon casters, steel casters, high-temperature resistant casters, rubber casters, and S-type artificial rubber casters.

We are a professional manufacturer of casters.
