  • Ball Screw Support bearing - BSN Series The BSN series of ball screw support bearing are double row, angular contact thrust ball bearing, with a 60° contact angle. They are equivalent to two single row bearing in a back-to-back arrangement, with a single outer ring. bearing are supplied ready to be mounted. They come greased with long life lithium soap grease, with synthetic hydrocarbon base oil. Under normal operating conditions, the bearing are greased for life. A relubrication groove on the outside surface of the outer ring allows the bearing to be relubricated during operation if necessary. The bearing are sealed on both sides. The low friction contact lip seal runs in a grove in the inner ring giving excellent sealing characteristics, while minimising torque and heat generation. Preload is set during manufacture so that the correct loading is achieved when the lock nut is tightened to the recommended torque. BSN-DT Series The matched DT pairs are essentially the same as the individual bearing. The two individual bearing have been matched together in the paired version. Both bearing have a V-shaped mark on the outer diameter to ensure that they are arranged correctly.
