Cylindrical roller bearings Luoyang Longma Bearing **** There are many types of cylindrical roller bearings, which are distinguished by structure, including N, NF, NJ, NU, NUP, NCL, RN and RNU types. In terms of load capacity, there are ordinary and reinforced cylindrical roller bearings. The dimensions of the reinforced cylindrical roller bearing are the same as those of the ordinary type, but the diameter, length and number of rollers have increased, so the load bearing capacity has increased.

Distinguished by the number of rows of cylindrical rollers, there are single row and multi-row cylindrical roller bearings. Cylindrical roller bearings are divided into four rows of cylindrical rollers and double rows of cylindrical rollers, with high radial load capacity, but can not withstand axial forces, small radial size, high limit speed, because the inner ring has no flange, so the inner ring and outer ring assembly can be installed separately (with a full set of rollers and cage). This kind of bearing has the advantages of large radial load capacity, high rotation accuracy, and convenient installation and disassembly for all kinds of cold and hot rolling mills with frequent roll replacement.

It is suitable for work rolls or back-up rolls on various hot and cold rolling mills, billet openers and other rolling mills.

Cylindrical roller bearings are mainly used in compressors, pumps, wind energy equipment, gearboxes, unbalanced shakers and other equipment.

The main parameters of cylindrical roller bearings: heavy-duty and high-speed capabilities; Able to withstand axial displacement; It is a separable design.

The mechanical design manual is very detailed!! You can go and find it.

Full load cylindrical roller bearings are designed to withstand heavy loads. At the same width, this bearing has an extremely high load carrying capacity compared to conventional bearings with cages, with a small radial cross-section, which saves space, but at a relatively low speed. In order for the bearing to work properly, the bearing must bear a certain minimum load, i.e. CP<25, in the case of continuous operation.

Otherwise, wear will be exacerbated by insufficient lubrication and high-speed operation. All multi-row cylindrical roller bearings have a lubrication groove and lubrication hole in the outer ring.

1. It has two inner rings, the two inner rings are connected together by the clamping ring, which cannot be separated, and the outer ring has a middle flange, which can bear the axial load in both directions and is used as a positioning bearing. Due to the large distance between the two rows of rollers, it can also withstand the overturning moment. There are two stop grooves on the surface of the outer ring, which can be positioned axially.

The bearings are fitted with contact seals on both sides, with lithium grease inside, and the operating temperature is limited to 40 +80 °C. Under certain conditions, this type of bearing does not need to be maintained, but when there is water vapor or pollution during operation, and it is often running at medium or high speeds, it must be lubricated. In the case of oil lubrication, the sealing ring needs to be removed, and the grease in the bearing should be cleaned, and the rotation should be increased by 30% when oil lubrication is used.

2. For the unsealed bearing, the outer ring is integrally split and fixed together by the connecting lock plate, so the outer ring can not bear the axial load, and the split outer ring is exactly the same, each with a flange, which can be axial positioning in two directions. The inner ring has three flanges. The outer ring has an oil groove and three lubrication holes, and these bearings are usually oil-lubricated.

3. It is a non-sealed bearing, with no flange in the outer ring, with oil groove and three lubrication holes. The inner ring has three flanges. The outer ring** is fitted with a retaining ring between the two rows of rollers, which prevents the rollers from falling out and keeps the bearing as one.

These bearings allow a certain axial displacement between the shaft and the housing to occur within the bearing. Because it can be used as a floating-end bearing.

4. The outer ring has a single flange, and there is a lock ring on the unflanged side, which can be used for one-way positioning of the machine shaft, and the axial clearance "S" inside the bearing ensures the axial positioning of the machine shaft relative to the bearing box.

5. It is used for extremely heavy load and low-speed occasions, with a self-locking roller group, even if the inner ring is removed, the rollers will not be scattered, so this type of bearing is easy to install and disassemble, can bear unidirectional axial load, and is positioned in one direction.

Rolling elements are centripetal rolling bearings of cylindrical rollers. The internal structure of cylindrical roller bearing adopts the rollers to be arranged vertically with each other at 90 ° (this is also the origin of the name of the cross roller bearing), and the rollers are equipped with spacer holders or isolation blocks, which can prevent the tilt of the rollers or the mutual grinding between the rollers, and effectively prevent the increase of rotational torque.
