Cylindrical Roller Bearings SKF NJ2313 ECP/C3

The SKF NJ2313 ECP/C3 single-row cylindrical roller bearing (65x140x48 mm) accommodates high radial forces and unilateral axial loads with a slightly increased bearing clearance.

This open cylindrical roller bearing NJ2313 ECP/C3 from SKF is designed as a support bearing for high mechanical loads. Due to the line contact of the rollers, the bearing primarily transmits high radial forces. With a bore of 65 mm, an outer diameter of 140 mm and a width of 48 mm, the component complies with standardised mounting dimensions. The inner ring is removable from one side, allowing both bearing rings to be fitted separately.

What is the NJ2313 ECP/C3 cylindrical roller bearing suitable for in operation?

The NJ design is used in bearing arrangements where strong radial forces and one-sided axial guidance forces are the primary loads. As a support bearing, the outer ring has two solid flanges, whilst the inner ring is designed with a single solid flange. This allows the bearing to guide the shaft in one axial direction whilst permitting a defined amount of axial displacement in the opposite direction. The optimised internal design ensures even load distribution across the raceways.

What are the advantages of a polyamide cage and C3 clearance?

The integrated polyamide cage reduces the moving mass of the rolling element assembly and dampens vibrations during operation. The bearing is designed for a temperature range of –30 to +120 degrees. The slightly increased C3 radial clearance helps to prevent the rollers from seizing should the shaft and inner ring expand due to heat. As this design does not feature sealing washers, the lubricant supply must be provided via the housing design.
