About Cylindrical Roller Bearing

Cylindrical roller bearings feature high radial load capacity because the rollers and raceway are in linear contact.
These bearings are suitable for applications that involve heavy radial and impact loading.
They are also appropriate for high-speed applications in that they can be machined very accurately due to their structure.
Having a separable inner ring or outer ring, these bearings can be mounted and dismounted easily.
The geometry allows for accurate machining to precision grade quality and uses at high speeds.
The inner or outer rings can be separated, simplifying mounting and removal of the bearing.

Single-row Cylindrical Roller Bearings

The NU and N types exhibit their best performance when used as free side bearings since they adjust to the shaft's axial movement, to a certain extent, relative to the housing position.
The NJ and NF types carry axial load in one direction, while the NUP and NH types can carry a certain degree of axial load in both directions.
Type R cylindrical roller bearings feature enhanced load ratings compared with standard series, though both have equal dimensions.
This is because type R bearings have a different internal design.
They are identified by supplementary code "R".

Main Applications

Automotive: Internal combustion engines transmissions, and cargo transportation
