Cylindrical Roller Bearings SKF NU319 ECP

The SKF NU319 ECP cylindrical roller bearing (95x200x45 mm) is a single-row non-locating bearing with a polyamide cage, designed for high radial loads in mechanical engineering.

The SKF NU319 ECP cylindrical roller bearing is an open, single-row rolling bearing designed for demanding industrial applications. With a bore of 95 mm, an outside diameter of 200 mm and a width of 45 mm, this design can withstand high radial loads. In the Explorer version, the bearing features an optimised internal design that reduces friction. The polyamide cage ensures quiet operation with normal radial clearance. You receive a disassemblable component for precise assembly procedures.

In which bearing arrangements is the NU319 ECP cylindrical roller bearing used?

This cylindrical roller bearing is particularly suitable for bearing arrangements subject to purely radial loads where thermal length changes in the shaft occur. As it is designed as a floating bearing, the inner ring can be removed from both sides, allowing axial displacement of the shaft relative to the housing to be compensated for freely within the bearing. Typical applications include shaft bearings in general mechanical engineering subject to high radial loads. As the bearing is of an open design, it is usually operated in sealed housings with an external lubricant supply.

What does the NU design with a polyamide cage mean for your design?

The NU design is characterised by two solid flanges on the outer ring and a flangeless inner ring. As a result, the bearing does not transmit any axial forces. Check in advance whether a fixed bearing provides axial guidance. The lightweight polyamide cage is designed for a temperature range of –30 to +120 degrees. With dimensional accuracy P0 (ABEC 1) and increased running accuracy to P6 (ABEC 3), the bearing offers reliable concentricity for industrial manufacturing standards.
