When INA bearing in 0.1 C load conditions operation, because with the way the body roll rolling contact surface of the contact stress between increases, the bearings working temperature, the performance of the lubricant relatively worse, therefore, deep groove ball bearing limit rotational speed will be reduced.

For C / = 10 range, due to the lower limit speed is very small, we can not be considered, namely the f1 = 1 value.

For bear joint load function to the heart bearings, because its bear a heavy load of the growing number roller, increase friction resistance, heat increases, lubrication and cooling conditions worse, and the effect on the shelf to keep the force also increase, so, must according to bearing types and load Angle of size, will deep groove ball bearing limit rotational speed multiplied by a lower coefficient f2 to make adjustments.

If the INA bearing of extreme speed speed can not meet the application requirements, can be made some improvement measures to improve the technology, in order to achieve a satisfactory requirements. Such as improving bearing tolerance level; Suitable enlargement of clearance; Switch to special materials and improve keep shelf structure; Change the lubrication methods, such as the oil and gas, oil mist and injection lubrication; Improved cooling conditions and so on.

First, bearing the lubrication service detection methods
In the operation should keep lubricant road unobstructed, regularly check the sealing of seal in time to replace the damaged the seal. And operational status monitoring, can from the noise. Lubricant, three aspects such as the temperature monitoring. For normal operation should be smooth buzz and the abnormal when handled in a timely manner, normal lubricant is clear and clean, if lubricant has become dirty, there will be wear particles or the pollutant, the temperature rises, the running will appear unusual.

Second, bearing the lubrication service concrete steps

1, the importance of lubrication
High attention INA bearing lubrication technology. Lubrication can use oil film will relative movement in the surface rolling separated from each other, not because of rough contacts lead to excessive wear and failure, can guarantee to set in the working life can still keep stable during the performance and the rotating precision.

2, the classification of lubrication
Divided into grease lubrication oil lubrication and grease lubrication, the advantage of lubrication facilities simple, grease is not easy to leak, have certain waterproof, gas and other debris into the ability, so usually widely used grease lubrication. In the heavy, high speed, high temperature condition oil lubrication.

3, grease, usage
Filling quantity want right amount. Best to fill the bearing and deep groove ball bearing a third of the half shell space and shall prevail, if fatliquoring too much, because the mixing and hot, can make the fat metamorphic progression or of qin. High speed should only fill to a third or less. When speed is very low, to prevent external foreign body into the INA bearings inside can full shell space.

4, bearing the storage
The storage and preservation of the environment of stricter requirements, such as temperature, humidity and so on. To do before they leave the factory are coated with temporary, room temperature should be controlled in 0-25 ℃, relative humidity should be maintained at 45%-60%.
