Cylindrical Roller Bearings SKF NJ2211 ECP/C3

The SKF NJ2211 ECP/C3 cylindrical roller bearing (55x100x25 mm) acts as a support bearing, accommodating high radial forces and unilateral axial loads with increased bearing clearance.

The SKF NJ2211 ECP/C3 cylindrical roller bearing is a single-row rolling bearing designed for industrial drive and machinery applications. With key dimensions of a 55 mm bore, 100 mm outside diameter and 25 mm width, this design is particularly suitable for high radial loads. Thanks to its optimised internal design and lightweight polyamide cage, the bearing runs with low friction on shaft guides. Design and maintenance engineers use this open roller bearing when defined tolerances and standardised dimensions are required in mechanical engineering.

What functions does the NJ2211 ECP/C3 cylindrical roller bearing fulfil as a support bearing?

The NJ design acts as a support bearing under high radial loads and guides the rotating shaft in an axial direction. Two fixed flanges on the outer ring and one fixed flange on the inner ring absorb unilateral guiding forces, whilst allowing free axial movement in the opposite direction. The inner ring can be removed from one side for assembly, which significantly simplifies the separate fitting of the inner and outer rings in practice.

What are the key features of the ECP and C3 variants?

The designation ECP stands for an optimised internal design with a polyamide cage, designed for operating temperatures ranging from –30 to +120 degrees Celsius. The C3 specification refers to a slightly increased radial bearing clearance. This increased operating clearance prevents the rolling elements from seizing if temperature differences arise between the rings during operation or if tight fits reduce the bearing clearance after press-fitting.
