The purpose of bearing lubrication is to reduce internal friction and wear of the bearing, to prevent burning, its lubrication effect. Today, Luoyang Boying Bearing Co. , Ltd. small editor to detail the purpose of cross-roller bearing lubrication.
Reduce friction and wear
In the ring, roller and the mutual contact part of the retainer that constitutes the cross-roller bearing, prevent metal contact and reduce friction and wear.
Extending the rolling fatigue life of fatigue life, in rotation, the rolling contact surface lubrication is good, then extended. On the contrary, the oil viscosity is low, the thickness of the lubricant film is not good, then shortened.
Drain the friction albest heat and cool
Circulation to oil method, etc. can be used to drain the heat caused by friction, or from the outside of the heat, cooling. Prevents overheating of cross roller bearings and the aging of the lubricant itself.
There is also a protection from foreign objects entering the inside of cross-roller bearings, or to prevent rust, corrosion effect.
The lubrication method of YRT turntable bearings is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, to choose suitable for the conditions of use, the purpose of use of lubrication methods. If lubrication is only considered, the lubricity of oil lubrication prevails. However, grease lubrication has the special ity that simplifies the structure around the bearing, comparing the pros and cons of grease lubrication with oil lubrication.
