Cylindrical Roller Bearings SKF NJ315 ECP

The SKF NJ315 ECP cylindrical roller bearing, with main dimensions of 75 × 160 × 37 mm, accommodates high radial forces and single-direction axial loads in mechanical engineering applications.

The NJ315 ECP cylindrical roller bearing is a single-row radial roller bearing from SKF with a 75 mm bore, an outer diameter of 160 mm and a width of 37 mm. Due to the line contact between the rollers and the raceway, this design can transmit high radial forces. The NJ design features two fixed flanges on the outer ring and one fixed flange on the inner ring. As a result, the design guides the shaft in the axial direction and acts as a support bearing.

When is the NJ315 ECP cylindrical roller bearing used as a support bearing?

This bearing is suitable for shaft mountings where high radial loads act on the bearing location. The support bearing design additionally accommodates axial guiding forces from one direction, whilst axial displacement of the shaft in the opposite direction remains possible. As the inner ring can be removed from one side, the component can be fitted separately. The open design requires a clean installation environment and a suitable supply of lubricant via the housing.

What are the distinctive features of the ECP design with a polyamide cage?

The ECP version combines an optimised internal design from the Explorer performance class with a lightweight polyamide cage. This cage reduces the weight of the rotating parts and promotes smooth running with normal radial clearance. The permissible operating temperature range is from –30 to +120 degrees Celsius. In terms of precision, the bearing combines dimensional tolerance class P0 (ABEC 1) with increased running accuracy to class P6 (ABEC 3) for precise concentricity on the shaft.
