FV Large Size Thrust Angular Contact Ball Bearing Model List for Rotary Tables

Freya2年前 (2022-07-21)Blog447

Rotary tables are the traditional solution to provide rotational force to turn the drill string. When drilling is interrupted, the Rotary tables can also act as a support device, carrying the full weight of the drill string. The bearing positions are therefore subjected to high radial and axial loads. Due to the above requirements, the thrust angular contact ball bearing with high axial load capacity is the first choice for the main bearing of the Rotary tables.

The following are the model lists of large size thrust angular contact ball bearings:

Principal Dimensions					Basic Load Ratings		Limiting Speeds		Weight	Bearing Number
mm					KN		r/min		kg	new	old
