Stainless steel bearing
Overview of bearings: Bearings are components that fix and reduce the friction coefficient of the load during mechanical transmission. It can also be said that, when other mechanical parts move relatively to each other on a shaft, these components are used to reduce the friction coefficient in the power transmission process and keep the central position of the shaft fixed.
Overview of bearings:
Bearings are components that fix and reduce the friction coefficient of the load during mechanical transmission. It can also be said that when other mechanical parts move relatively to each other on a shaft, bearings are used to reduce the friction coefficient in the power transmission process and keep the shaft's central position fixed. Bearings are crucial components in modern mechanical equipment. Their main function is to support rotating mechanical bodies to reduce the friction coefficient of the mechanical load during transmission. According to the nature of the friction of the moving elements, bearings are divided into roller bearings and sliding bearings.
Purpose of lubrication for stainless steel bearings:
The purpose of lubrication for roller bearings is to reduce internal friction and wear of the bearing and prevent seizure due to heat. Its lubricating effects are as follows.
1. Reduce friction and wear
In the mutually contacting parts between the races, rolling elements, and the separator that make up the bearing, metallic contact is avoided to reduce friction and wear.
2. Prolong fatigue life
The rolling fatigue life of the bearing is extended if the lubrication of the rolling contact surface is good during rotation; conversely, if the oil viscosity is low and the lubricating film thickness is insufficient, it shortens.
3. Remove frictional heat and cool
Methods such as circulation lubrication can remove heat generated by friction or external heat through oil, thus cooling the bearing. This prevents bearing overheating and lubricant aging.
4. Others
It also has effects to prevent the entry of foreign bodies inside the bearing or to prevent oxidation and corrosion.
