The Purpose and Method of Single Row Self-Aligning Roller Bearings Lubrication

The purpose of lubricating single-row spherical roller bearings is to reduce internal friction and friction of the bearing, prevent burning sticking, and lubricate the lubrication effect.

⑴ Reduce friction and friction

 In the contact parts of the rings, rolling elements, and retainers that make up the bearing, metal contact is prevented from reducing friction and wearing.

⑵Extend fatigue life

The rolling fatigue life of the bearing is prolonged when the rolling contact surface is well lubricated during rotation. Conversely, if the oil viscosity is low and the lubricating oil film thickness is not right, it will be shortened.

⑶Discharge frictional heat and cooling

The circulating oil feeding method can use oil to remove the heat generated by friction, or the heat transferred from outside to cool. Prevent the overheating of bearings and prevent the aging of lubricating oil itself.

⑷Other

It also prevents foreign objects from intruding into the bearing or preventing rust and corrosion.

 

Bearing lubrication methods are divided into grease lubrication and oil lubrication. To make the bearing function well, first of all, it is necessary to choose a lubrication method suitable for the conditions of use and purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant. However, grease lubrication simplifies the structure around the bearing and compares the advantages and disadvantages of grease lubrication and oil lubrication.
