Cylindrical Roller Bearings SKF NU316 ECP/C3

The SKF NU316 ECP/C3 cylindrical roller bearing, measuring 80 × 170 × 39 mm, serves as a support bearing to accommodate high radial loads during thermal length changes.

The single-row cylindrical roller bearing NU316 ECP/C3 from SKF is designed for industrial applications involving purely radial force transmission. Thanks to the line contact between the rollers and raceways, this design can accommodate heavy loads. The optimised internal geometry and the polyamide cage ensure quiet operation. As an open roller bearing, the bearing assembly can be flexibly integrated into existing lubrication circuits via the housing.

What is the NU316 ECP/C3 cylindrical roller bearing suitable for?

This bearing is primarily used in bearing positions where high radial loads occur and axial length changes in the shaft need to be compensated for. The NU design features two fixed flanges on the outer ring, whilst the inner ring is flangeless. This allows the rings to move freely relative to one another inside the bearing during thermal expansion, without generating axial constraint forces. Typical applications include shaft mountings requiring thermal displacement.

What do the NU design and C3 clearance mean for your design?

The C3 classification indicates a slightly increased radial clearance compared to the standard. This clearance compensates for fit allowances after press-fitting, as well as temperature differences between the shaft and housing, ensuring that the bearing does not seize during operation. As the inner ring can be removed from both sides, you fit the bearing rings separately onto the shaft and housing. This simplifies workshop assembly and saves valuable maintenance time during scheduled overhauls.
