Four-point contact ball bearings, also called “Duplex Bearings”, belong to the single row angular contact ball bearings family, with split inner ring . The contact geometry between rolling element and raceway is “four-point ” contact, due solely to raceway form design. These bearings are able to support thrust loads in either directions including limited radial loads. Where necessary there are locating grooves in the outer rings to prevent undesirables rotation.Four-point contact ball bearings of the “QJ” design feature a contact angle of 35° and have split inner rings to allow the bearing to accept the maximum number of balls. Due to the split inner rings, these bearings are separable and this facilitates mounting because the bearing outer ring thereto with cage and ball set and the inner ring halves may be mounted separately. Four-point contact ball bearings are frequently used to accommodate thrust loads only. To avoid unwanted radial loading to the bearing they used to be mounted to oversized housing seats. To prevent the outer ring form rotating in the housing, outers ring are often equipped with locating slots. For this reason, four point contact ball bearings are produced with two locating slots in their outer ring, and they are positioned at 180 ° C of each other identifies with the suffix N2. Special series of four point contact ball bearings are available on request by the series Q10 and four-point contact ball bearings with split outer ring ( series Q) .HTB1lDuXG29TBuNjy1zbq6xpepXaC
