Form of rolling bearing types and a wide range of sizes, to choose the most appropriate to achieve the designed bearing from the mechanical conditions of use, the performance requirements of the bearing, bearing the surrounding Specificatio ns until the market and economic and other aspects of the comprehensive Analysis.
Generally make sure the shaft diameter and then select bearing, the first bearing diameter based and consider the bearing space for installation and configuration and other conditions, initially identified the type of bearings; Second, the analysis of mechanical requirements bearing life with bearing load bearing life calculation "to determine the size of the bearing; Finally, a fundamental need to determine the accuracy level, internal clearance, keep the frame, lubricants bearing internal structure.
Select the general steps of:
1, the bearing type and configuration determine. (Reference factors: the installation space of the bearing; bearing the load size, direction and nature; speed; rotation accuracy; noise and friction torque; rigid; inner and outer rings relative inclination; installation and removal; bearing configuration; market and economy). roller bearing manufacturers
2, to determine the size of the bearing. (Mechanical requirements, bearing life; equivalent dynamic load; equivalent static load; speed; bearing size; basic dynamic load rating; basic static load rating; allowable axial load).
3, the determination of the accuracy class. (Rotation accuracy; noise and friction torque; speed; bearing accuracy).
4, with the internal clearance. (The size and nature of the load; temperature of operation, respectively; the material, size and precision of the shaft and the housing; complex; temperature difference between the inner and outer rings; speed; preload; bearing precision; bearing internal clearance).
5, the cage material and type. (Speed; noise).
6, the special environment corresponding measures. (Medium conditions, such as temperature, seawater, vacuum, pharmaceuticals, dust, gas, magnetic field, etc.; special materials; special heat treatment; special surface treatm ent; lubricant). abec 7 bearings
7, lubrication, lubricants and sealing device. (Using temperature; speed; lubrication; lubricant; sealing device; bearing speed limit; the grease life).
8, installation and removal and installation size.
9, the bearing and its surrounding specifications finalized. Ultimately the performance to meet the requirements of the bearing.
