Four Point Contact Ball Bearings

Short Description:

Four-point contact ball bearing is a kind of double direction single row angular contact ball bearing. Due to the exceptional design of raceway grooves of inner ring and outer ring, there are two contact points between each raceway groove and a ball. The contact angle is 35°. These bearings are able to carry axial loads in double directions. The speed limits of these bearings are very high and they are specially suitable foe high speed applications.

    Four-point contact ball bearing is a kind of double direction single row angular contact ball bearing. Due to the exceptional design of raceway grooves of inner ring and outer ring, there are two contact points between each raceway groove and a ball. The contact angle is 35°. These bearings are able to carry axial loads in double directions. The speed limits of these bearings are very high and they are specially suitable foe high speed applications.

    A four-point contact ball bearing is composed of one outer ring with “peach shape”section raceway groove, a pair of two-piece inner ring, and one assembly f ball set with a machined brass cage, forming four point contact. The four point contact ball bearings are mainly used in the applications of machine tools, power transmissions of large diesel engines as supports and carrying high thrust loads.
