RSBW30 sprag type freewheel one way clutch bearing

In the one-way bearing is free to rotate in one direction, while in the other direction to lock a bearing. Also called a one-way clutch bearing, but depending on the industry, the role of different named. The metal in the one-way bearing, comprising a number of rollers, roller or ball, and the rolling seat (hole) shape rolling it in only one direction and in the other direction generates a large resistance (The so-called "one-way").

Entity using one-way bearing GCr15 bearing steel, heat-treated hardness HRC61-65, bearing small size and high load carrying capacity, there is enough storage space for grease, may have come a long lubrication intervals.

One-way bearing: HF, HFL, FC, FCB, RCB, RC, F, IWC, EWC, DC, CSK, CKB (B200), ASNU, CKA, FWD, NF

RSBW is a DC sprag type freewheel. It is self-contained,  centered by plain bearings for  low rotational speeds and sealed using shield protected Outer Rings.

 

Unit is delivered grease lubricated ready for installation in either a horizontal or vertical position. 

 

Primarily used as a backstop, this type provides a high torque capacity with a minimum space

 

requirement.
The design allows installation in difficult environments such as high humidity or water splash areas.

 

A bolt, secured to a fixed part of the machine and passing through the slot in the torque arm, 

 

provides the rotational stop. Radial clearance on this bolt should be equal to 1-3 % of the slot 

 

width. The torque arm and the bearings must not be prestressed.
