Cylindrical Roller Bearings SKF N312 ECP

SKF N312 ECP single-row cylindrical roller bearing with a 60 mm bore, 130 mm outer diameter and a polyamide cage for radial loads.

As a single-row cylindrical roller bearing, the SKF N312 ECP withstands high radial loads. Thanks to the line contact between the rollers and raceways, this rolling bearing can withstand high loads during operation. In the version with an optimised internal design and Explorer performance class, the component combines compact dimensions of 60x130x31 mm with smooth running and stable guidance at high speeds.

What is the N312 ECP cylindrical roller bearing suitable for as a floating bearing?

This design is used at bearing locations where thermal linear changes in the shaft need to be compensated for. The N design features fixed flanges on the inner ring, whilst the outer ring is flangeless and removable from both sides. As a result, the component compensates for axial displacements within the bearing itself without inducing stress. Typical applications include general mechanical engineering, gearboxes or shaft guides that are axially guided by a separate fixed bearing.

What is the function of the polyamide cage and the open design?

The polyamide cage guides the cylindrical rolling elements with low friction and dampens operating noise. The component operates within a temperature range of -30 to +120 degrees Celsius. As an open roller bearing without integrated sealing washers, it is designed for integration into existing lubrication circuits. To prevent the ingress of contaminants, the bearing housing therefore requires external sealing on the casing.
