The trouble and avoidance of Mini cylindrical roller

Accurate diagnosis of Mini cylindrical roller is of great significance to prevent repeated failures and increase costs.

Mini cylindrical rollers are now used in most mechanical applications. These Mini cylindrical rollers are very reliable even under the worst conditions. They have a long service life under normal working conditions.

The latest research shows that only one percent of the Mini cylindrical rollers can not reach the expected service life.

This shows that the premature failure of Mini cylindrical roller is mainly due to avoidable reasons.

Most Mini cylindrical roller failures, such as spalling, pitting, spalling, flexing, creep, corrosion, rust and abnormal wear, are caused by relatively few causes.

These reasons are usually interrelated and can be corrected at the same time.

The main reasons of Mini cylindrical roller failure include installation, working stress, environmental impact and bearing selection.

Proper lubrication is very important for prolonging the service life of Mini cylindrical rollers. It helps to cover rolling and sliding surfaces with a thin layer of oil, thus avoiding direct contact between metals.

This helps to reduce wear and friction and extend the service life of the Mini cylindrical rollers.

Grease is used to lubricate surfaces because it is easy to handle and helps simplify the sealing system.

Oil is a good lubricant for high temperature or high speed operation.

Lubricating oil failure may be caused by the following reasons: using the wrong lubricating oil, using too much grease or lubricating oil, using too little grease or lubricating oil, mixing grease and lubricating oil or using contaminated grease / lubricating oil.

Proper tools must be used during installation and installation.

In order to prolong the service life of the Mini cylindrical roller roller, the misalignment and deflection of the shaft should be minimized.

Working pressure is another cause of bearing failure.

In general, factors in large applications can change at any time. If the load is too high, it may cause overload and premature pressure.

Similarly, if the load is too low, it may slip. Abnormal noise and high temperature are the first signs of such problems. This is how the working stress in the application affects the Mini cylindrical roller life.

Overcome these problems, you will get the maximum service life of each Mini cylindrical roller!

Poor lubrication between the needles is due to a serious lack of lubricant. Therefore, according to the running time of the motor, the state of the load, the ambient temperature and the quality of the grease, the time of replenishing the bearing can be determined. The strong vibration is due to the vibration of the motor core, which leads to the violent vibration of the bearing. When this happens, we have to replace the needle roller bearing with the same model.

Material fatigue is caused by the fatigue of metal materials, debris falling from the needle raceway and grease falling into the ball surface, which increases the working noise. Therefore, normal fatigue of Mini cylindrical roller material should be considered, and new bearings of the same type should be replaced. Check the raceway and ball surface for red and brown spot corrosion.

If the needle surface is corroded, clean the bearing surface first. It is necessary to choose the appropriate method according to the properties and main conditions of the antirust surface. Generally, there are more solvent cleaning methods, chemical cleaning methods and mechanical cleaning methods. After cleaning, it can be dried with filtered dry compressed air, or in a dryer at 120-170 ℃, or with clean gauze.

The stamping outer ring Mini cylindrical roller is immersed in antirust grease, and a layer of antirust grease is attached on the surface. The thickness of oil film can be obtained by controlling the temperature or viscosity of antirust grease. When assembling the bearing, the production personnel should wear gloves, finger sleeves or use special tools to pick up the bearing, and do not touch the bearing surface with hands.
