238/670CAMAW20 Roller Bearing 670x820x112mm for wire cable equipment

The spherical roller bearing 238/670 CAMA W20 consist of inner ring and outer ring and cage with roller. The bearing belongs to thin series structure and need to carry heavy load.The arrangement of the guide ring as well as the cage execution are different for the various designs.
The bearing cage material can use steel or brass available.

The inner ring of spherical roller bearings have two raceways, outer raceway is a part of a sphere, whose curvature center is on the axis of bearings. This type of bearings possesses self-aligning performance, allowing the misalignment of shaft, and can also be used under certain permanent misalignment.
These bearings are able to carry higher radial loads, as well as certain axial loads, but can’t be used to carry pure axial loads. The osculation between rollers and raceways is high, and friction is higher than cylindrical roller bearings. Therefore, the limiting speed is lower.
