Cylindrical Roller Bearings SKF NU2206 ECP/C3

SKF NU2206 ECP/C3 single-row cylindrical roller bearing as a non-locating bearing with a 30 mm bore, 62 mm outer diameter and a polyamide cage for high radial loads.

The SKF NU2206 ECP/C3 cylindrical roller bearing is a single-row free-running bearing with an optimised internal design. Thanks to the line contact between the rollers and the raceway, this design can accommodate high radial forces. The open design makes the bearing suitable for oil- or grease-lubricated systems. The inner ring can be withdrawn from either side, which facilitates both installation and removal and allows axial length changes of the shaft within the housing to be compensated for without constraint.

In which installation situations does the NU2206 ECP/C3 cylindrical roller bearing act as a non-locating bearing?

This cylindrical roller bearing is primarily used in bearing arrangements subject to purely radial loads. As the outer ring has two fixed flanges and the inner ring is flangeless, the design functions as a pure non-locating bearing. If thermal expansion of the shaft occurs during operation, the inner ring moves axially with minimal resistance relative to the roller set. This helps to protect adjacent components from axial stress.

What does the ECP design with C3 clearance mean?

The suffix ECP denotes an optimised internal design in combination with a lightweight polyamide cage. This cage operates with low vibration and is designed for operating temperatures ranging from –30 to +120 degrees. The suffix C3 indicates a slightly increased radial clearance. This additional clearance counteracts any distortion of the rolling elements when tight shaft fits cause the inner ring to expand or when operational heating occurs. Furthermore, the bearing offers dimensional accuracy to P0 and increased running accuracy to P6.
