Four-point Contact Ball Bearings

Four-point Contact Ball Bearings

Four-point contact ball bearing is a type of single-row angular contact bearing, and it belongs to separable bearings. The steel balls contact the four points of ferrule, with a contact angle of 35กใ. The four-point contact ball bearing can be subject to radial load and axial load in any direction or radial and axial combination load. Double-sided axial displacement of shaft or housing is limited in axial windage range of bearing by this type of bearing. Compared with other ball bearings, when axial windages are the same, the axial windage of this type of bearing is smaller, the load capacity is larger, and the limit speed is higher.
