Products'details

 

Cylindrical Roller Bearings are bearins in which cylinders are used as the roller elements as opposed to balls in ball bearings.As such,the rollers have a greater(linear)contact area with the outer ring and are distribute loads across a broader surface.Subsequently,they have a relatively high radial capacity and are suitable for high speed.

Single row cylindrical roller bearings are also manufactured with snap ring grooves on the outer rings.This design simplifies the bearing joint as the bearings are located into the housing by the means of the snap rings.This snap rings groove and snap rings are in accordance with ISO 464.

There are different types designated NU,NJ,NUP,N,NF for single row bearings.
