The bearings of roller skates are cleaned and oiled. Do roller skate bearings have to be lubricated

Generally, the cleaning of roller skate bearings is divided into the following steps:

1.Remove the wheels from the shoe. The way to remove the wheels depends on the different specifications of the shoes, and the wheels are generally removed using a hexagon wrench.

2.The bearings are removed from the wheels. There are two types of bearings on wheels, and sometimes it may be necessary to use special tools or small objects to eject the bushing.

3.Remove the cover of the bearing. Generally, the cover of the C ring is attached to the bearing, which can be easily removed, and if it is slightly more difficult, it can be disassembled with the help of other removal tools.

4.Cleaning the bearings. Place the removed bearing into a sealable container, such as a regular beverage bottle, but the opening should be large enough to fit into the bearing. Then pour in the derusting lubricating cleaner or kerosene, shake repeatedly, and then let stand for about 10 minutes.

5.Remove the cleaned bearing. Take the cleaned bearing out of the container, put it on a paper towel or cloth, let it dry, and then put a special lubricating oil on the steel ball, turn the wheel more than ten times, and then install the cover on the bearing.

6.Install the wheels. After attaching the bearings to the wheels, reattach the wheels to the shoes. A pair of clean and durable shoes has reappeared.

In fact, roller skates are troublesome and dirty, and the effect is not good, and one or two will produce dependence. I've been playing for more than four years, and I haven't oiled it from Seba-H to EVO, so it's good to clean it regularly, and it won't be too rusty when I play often, and I changed the bearings in about a year and a half. I was oiled when I wore T105 before, it was very dirty, and I was nauseous.

Oiling is required. The bearings may be rusty.

Find a needle and use the tip of the needle to pick open the oil seal. Then use gasoline or other cleaning agent to clean the bearings and then oil them.

Put a little oil on it and take a look.

Lubricants for wheel bearings include high-speed butter and spindle oil.

The lubricating oil used for roller skate bearings is butter, and the cavity is also called grease. Due to the high viscosity of butter, it is normal for the freshly oiled wheel to not turn easily. Don't use a running machine oil, and don't use a thinner sewing machine oil or transformer oil.

The oil film formed by the low viscosity oil hail on the friction surface of the bearing is thin and weak, which is easy to be destroyed, resulting in direct contact wear of the metal. On the other hand, there is a gap in the dust cover of any kind of bearing, and the dust will inevitably enter during operation, and the oil with high viscosity will block the dust at the nearest part of the gap, while the oil with low viscosity can not make the dust stir to the entire lubrication space, so that the oil will turn black and fail in advance.

Gasoline, kerosene, diesel, cleaning agent for repairing car engines, etc., can be used for cleaning, and the oil washed for the first time becomes dirty and black, and the second oil or the third oil for the shirt should be cleaned. In addition, if there is no oil, you can also soak the bearing with hot laundry detergent water, brush and remove the oil with a small brush, and then wash it with hot water to dry, and apply butter as soon as possible to avoid rust.

Whether the shaft of the roller skate has a shoulder, and if there is no shoulder, there should be a spacer to hold the distance between the two bearings. Imagine, if the shaft hole where the outer ring of the two bearings is not worn, and the screw is tightened, this force is acting on the inner ring of the bearing, if the inner ring is not fixed, the wheel will definitely not be able to rotate. It is not recommended to clean disassembled bearings; It is recommended to replace the new bearing, if it is a bearing of 608 or similar size, about 15 yuan can buy authentic imports, such as SKF, NSK, etc.; The domestic 5 yuan or so is about the same.

If the above situation cannot be solved, please find a professional repair agency.

Just wipe it with a tissue paper.,It's okay.。。。

It is not necessary, but the type of roller skate bearing is generally a ball bearing, and lubrication with butter can have the greatest adhesion and lubrication effect to protect the ball of the bearing.

Precautions for protecting bearings:

1. Do not slide in a place with water, if you accidentally splash into the water, you should remove the bearing and wipe it clean with a dry towel to prevent rust.

2. Do not slide on the road surface with sand and gravel, once there are fine sand particles into the bearing and inside, the ball will soon be destroyed, resulting in the bearing can not be used normally.

3. After sliding every day, remove the bearing and wipe it to keep the surface of the bearing clean and dry.

4. After one month of use, if there is any abnormal noise, please carry out professional maintenance. Go to a designated store and have it maintained by a professional. First of all, professionals should open the bearing cover, boil the bearing and bearing cover in boiling water, after the dirt is boiled, rinse the bearing and bearing cover with clean water, and then dry, and then add special oil for the bearing, and then close it after the oil is uniform between the bearing grains.

If the bearing is regularly maintained according to the above maintenance methods, the service life of the bearing can be greatly extended.

Butter (a popular name, such as a person's alias) is grease, and grease is a kind of petroleum lubricating oil, which is a paste similar to a solid mainly used for mechanical parts that are not easy to flow, such as bearings, gears, tracks, shafts, etc.

You can use calcium-based fats, lithium-based fats.

Yes, because the other slippery oils will fall.

Rolling bearings are precision matching parts, which should be scrubbed with gasoline and cloth, and it is strictly forbidden to scrub with cotton yarn. When cleaning on the shaft, in the case of double-row conical rollers, the town uses an injection gun to beat the hot oil, so that the old thousand oil is washed away by the hot oil. After the old oil is removed, you can spray gasoline once to completely remove the residual oil inside, if you use compressed air to blow it before injecting gasoline, blow off the remaining oil, you can save gasoline.

Ball bearings that are hardened or difficult to clean can be washed with oil at a temperature of 70 to 80<, then cleaned with kerosene, and finally washed with gasoline. After the bearing is washed, it should be replaced with new oil.

Sometimes due to the poor protection of the equipment, there is moisture inside, and there is a layer of rust on the processing surface, although the rolling bearing is alloy steel, there will still be rust. When cleaning, you can mix chalk ash with engine oil, apply it to flannel or flexible leather, and wipe the rusty areas; Or use a zero-abrasive cloth to remove the coarse sand on the surface, or dip it in dilute engine oil to wipe the rusty area. However, it should be noted that the processing surface should not be rubbed with lines, and rough tools should not be used to grind, so as not to affect the accuracy of the bearing.

If there are no other maintenance items on the bearings on the fan shaft or motor shaft, the bearings do not have to be removed. However, it is difficult to clean the bearings installed on the shaft, and it is not easy to clean the inside. The following describes a method and procedure for cleaning with hot oil:

1) Rinse the bearing with hot machine oil with an oil temperature of 90 loot to make the old dry oil on the shaft melt easily, and turn the bearing slowly.

2) Wash the melted dry oil in the bearing with kerosene, and the bearing will appear clean. When cleaning with kerosene, you can spray flush with a grease gun, and the bearings are easier to clean.

3) After washing with kerosene, clean again with gasoline. Because kerosene contains water, it is not easy to volatilize and will rust the bearing, so it must be cleaned with gasoline at the end.

1: Remove and wipe off the floating dust and open the dust cover.

2: Find a clean (no water) bottle of about 500ml, the diameter must be larger than the diameter of the bearing, and the diameter of a waste wire about 40 cm is 5mm

3: Tie a knot at one end of the wire, then put 8 processed bearings through the waste wire like a necklace and put them in the bottle.

4: Inject 100ml of sewing machine oil Regular engine oil is OK 5: Close the lid and shake the bottle gently.

6: Shake for 30 minutes to pour out the already dirty sewing machine oil to clean as clean as possible 7: Pour in clean sewing oil over the bearing and leave it for 48 hours 8:

Take out the bearing, cover it with a dust cover, put it into the skateboard, idle it at high speed for 5 minutes, wipe off the excess oil, and the care process of the skateboard bearing is completely introduced.
