NSK NU211ETC3 Cylindrical Roller Bearing

Description

The NSK NU211ETC3 is a high-performance single-row cylindrical roller bearing designed for applications demanding high radial load capacity and high rotational speeds. This bearing features a separable inner ring, which simplifies the mounting and dismounting process. The polyamide cage ensures low friction and reliable operation, while the C3 internal clearance accommodates thermal expansion.

FAQ

The suffix denotes specific features of the bearing. 'E' indicates an optimized internal design for higher load capacity. 'T' specifies a polyamide cage. 'C3' refers to an internal clearance that is greater than the standard 'Normal' clearance, which is suitable for applications with temperature differentials or tight fits.

Yes, the 'NU' design means the inner ring has two integral flanges and the outer ring is flangeless. This allows the inner ring to be removed and mounted separately from the outer ring and roller assembly, which can simplify installation.

A polyamide cage (suffix 'T') is lightweight, has good sliding properties, and can operate with low noise levels. It is also resistant to many common industrial chemicals and offers excellent performance in high-speed applications, provided operating temperatures do not exceed its limits (typically around 120 deg C).
