Selection of rolling bearing oil

The lubricating oil of the main shaft bearing using rolling bearings is generally considered comprehensively according to the product of the bearing inner diameter d and the main shaft speed n, that is, the speed factor dn, the bearing operating temperature T, the load P borne by the bearing and other parameters. The following is the selection of recommended lubricating oil grades for rolling bearings. The types of lubricating oil can be selected from FC or FD bearing oil, HL hydraulic oil, TSA turbine oil, DAD compressor oil, gasoline engine oil or cylinder oil, etc., depending on the product type, working conditions and viscosity grade

Main factors affecting bearing vibration

1. The vibration system composed of stiffness, flexibility, mass, damping, etc. determined by the bearing structure design parameters will produce vibrations that are compatible with its mechanics under operating conditions 2. Vibration caused by deviations in manufacturing and processing. The smaller the deviation, the smaller the vibration. The roundness, waviness, and surface roughness of the steel ball surface are the factors that have the greatest impact on vibration among all bearing parts, followed by the shape error and surface roughness of the inner and outer ring grooves, and then the bearing cleanliness and lubricant quality. 3. Operating conditions such as installation conditions, speed, axial load direction, value, etc.
