Cylindrical Roller Bearings SKF NU2214 ECP

The SKF NU2214 ECP cylindrical roller bearing, measuring 70x125x31 mm, provides a free-running bearing solution for high radial loads in mechanical engineering.

The NU2214 ECP cylindrical roller bearing is a single-row radial roller bearing from SKF’s Explorer performance class. Thanks to its cylindrical rolling elements, the design can accommodate high radial loads. This model has a bore of 70 mm, an outside diameter of 125 mm and a width of 31 mm. The outer ring has two fixed flanges, whilst the flangeless inner ring can be removed from both sides.

In which applications does the NU2214 ECP cylindrical roller bearing prove its worth?

The single-row bearing is primarily used as a conventional non-locating bearing. As the shaft and housing may expand differently in response to temperature changes, the NU design compensates for axial length changes directly within the rolling element system without causing any binding. This design is suitable for bearing arrangements in which only radial loads are applied and the inner ring is required to remain axially movable.

What are the distinctive features of the version with a polyamide cage?

The design suffix ‘P’ denotes the polyamide cage, which guides the rollers and is lightweight. The open bearing is designed for a temperature range of -30 to +120 degrees Celsius. Thanks to the separately mountable inner ring, installation with tight fits is straightforward. The outer ring is designed without a lubrication groove, which is why the lubricant is supplied via the housing.
