Product Description

Four Row Contact Ball Bearing:-

Four-point contact ball bearing is a type of single-row angular contact bearing , and it belongs to separable bearing . The steel balls contact the  four point of ferrule , with a contact angle of 35". 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 same , the axial windage of this type of bearing is smaller , the load capacity is larger , and the limit speed is higher.

This type of bearing is mainly used to be subject to axial load. It is uesd as thrust bearing with definite axial windage and mounted in bearing in bearing box in many occasions , Except normal four-point contact ball bearing ,there is also a type of four-point contact ball bearing whose suffix has N2 , Two locating slots are positioned on the outer race end of this type of  four -point contact ball bearing to facilitate locating and prevent the outer race rotating .
