Factory selling High Damping Rubber Bearing - PNA12/28 Alignment needle roller bearings, with an inner ring – CWL Detail:

Alignment needle roller bearings have an outer ring with a sphered outside surface. Two polymer seating rings with a sphered inside surface are encased in a drawn sheet steel sleeve and fitted over the outer ring.This design enables the bearing to accommodate static misalignment of the shaft relative to the housing.In applications where the shaft cannot be hardened and ground, bearings with an inner ring should be used. The permissible axial displacement of the shaft relative to the housing is limited for bearings with an inner ring. If the permissible axial displacement provided by a standard inner ring is insufficient, it is possible to use an extended inner ring.

Bearings without an inner ring are an excellent choice for compact bearing arrangements, if the shaft can be hardened and ground.

The Features of PNA12/28 Alignment needle roller bearings

Accommodate static misalignment:Alignment needle roller bearings are self-aligning up to 3° of static misalignment.

Low cross section:In applications where less space is available, alignment needle roller bearings offer a compact solution.

High carrying capacity:Owing to their large number of rollers, alignment needle roller bearings have a high load carrying capacity.
