Product Feature



Depending on the existence of ribs on their rings,Cylindrical

Roller Bearings are classified into following types.Type NU.N,

NNU,and NN are suitable as free-end bearings.Types NJ and

NF can sustain limited axial loads in one direction.Type NH

and NUP can be used as fixed-end bearings.NH-type cylindrical

roller bearings consist of the NJ-Type cylindrical roller bearings

and HJ-type L-shaped thrust collars.

Cylindrical Roller Bearings are bearing in which cylinders are

used as the rolling 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 load capacity

and are suitable for high speeds. Double-row cylindrical roller

bearings have high radial rigidity and are used primarily for

precision machine tools.
