Cylindrical Roller Bearings SKF NJ2310 ECP

The SKF NJ2310 ECP cylindrical roller bearing, measuring 50x110x40 mm, offers high radial load capacity and single-sided axial guidance when used as a support bearing.

The SKF NJ2310 ECP cylindrical roller bearing is a single-row roller bearing with an optimised internal design in the Explorer series. It has a bore of 50 mm, an outside diameter of 110 mm and a width of 40 mm. Thanks to the line contact between the rollers and the raceway, the design can withstand very high radial forces. The open bearing operates with standard radial clearance and functions reliably within a temperature range of -30 to +120 degrees Celsius.

What loads can the NJ2310 ECP cylindrical roller bearing withstand as a support bearing?

The bearing is designed as a support bearing for high radial forces and unilateral axial forces. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. This enables the bearing to support primary radial loads whilst simultaneously fixing the shaft in the axial direction. In the opposite direction, the design allows for axial displacement, which compensates for thermal length changes in the shaft.

What are the distinctive features of the polyamide cage in the ECP design?

The suffix ECP denotes an optimised internal design and a polyamide cage. This cage reduces the component’s weight and promotes smooth running with low friction. The inner ring is removable on one side, allowing the bearing rings to be fitted separately. With dimensional accuracy to tolerance class P0 (ABEC 1) and increased running accuracy to P6 (ABEC 3), the component meets defined industry requirements.
