32928 Tapered roller bearings

The small load Fmin required for tapered roller bearings can be estimated by the following formula:

Fmin = 0.02C

Shizhong

C – Basic rated dynamic load, KN

In the case of starting at low temperatures or high lubricant viscosity, a larger smaller load may be required. Under normal circumstances, the weight of the bearing support itself plus the load borne by the bearing has exceeded the smaller load required. If the smaller load is not reached, the bearing must be subjected to additional radial loads, such as axial preloading of the bearing, to meet the requirements of the smaller load.

Dimensions, tolerances, clearance

The dimensions of standard angular tapered roller bearings are in line with GB/T273.1 “General Dimensions of tapered Roller Bearings of Rolling Bearings”, GB/T297 “Dimensions of tapered roller bearings of rolling bearings”, GB/T299 “Dimensions of double-row tapered roller bearings of rolling bearings”, GB/T300 “four row tapered roller bearings of rolling bearings Dimensions, etc.

The tolerance of the standard tapered roller conforms to the provisions of GB/T307.1 “Rolling bearing bearing tolerance”.
