Cylindrical Roller Bearing  Inner Diameter: 50-1600 mm

Double-row Cylindrical Roller Bearing  Inner Diameter: 90-800 mm

Four-row Cylindrical Roller Bearing  Inner Diameter: 50-1030 mm

With the roller and the tracking surface in a line contact, cylindrical roller bearing has a large capacity of radial load, which suits for heavy load and impact load.

Being easy to be processed with high precision in its structure, it is suitable for high speed spinning.

 

With its Inner ring and outer ring separable, it is easy for assembly and disassembly.

Single-row Cylindrical Roller Bearing

Type NU and Type N allow axis to make axial movements in a certain range in the housing, which are most used as free-end bearings.

Type NJ and Type NF can withstand one-way axial load in a certain degree, while Type NUP and Type NH can withstand two-way axial load in a certain degree.

With its main sizes up to the standard cylindrical roller bearing, it raises the rated load through changes in the internal specifications.

Double-row Cylindrical Roller Bearing

There are 2 kinds of double-row cylindrical roller bearings: one with cylindrical bore and one with tapered bore. Bearings with tapered bore can obtain the internal clearance by adjusting the push-up distance.

Bearings with oil holes and oil grooves in the outer ring have a post positive auxiliary code —“W”in the nominal type。

With strong rigidity of load resistance, they are mostly used in machine tool spindles etc.
