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
• Electrical: Large and medium sizes motors, traction motors, and generators
• Industrial: Gearboxes and machine tool spindles, steel mills
