Retaining Ring WR (WR7)

A dedicated stop ring used when the track ring or retainer of a needle roller bearing is fixed in the axial direction, or guided.

[Features]
· Although the shape is the same as a C-shaped concentric retaining ring as specified in JIS B 2804, this product has been manufactured to a smaller cross-sectional height (b) to accommodate a needle shaped bearing and to an even smaller size range.
· Using a hard steel wire, a chemical treatment is applied to the surface.
