NSK Ball screw support bearing types :

BSN series :

The BSN series of ball screw support bearings are double row,angular contact thrust ball bearings,with a 60° contact angle. They are equivalent to two single row bearings in a back-to-bac arrangement, with a single outer ring.Bearings are supplied ready to be mounted.They come greased with long life lithium soap greasewith synthetic hydrocarbon base oil.Under normal operating conditions,the bearings are greased for life.A relubrication groove located on the outside surface of the outer ring allows the bearins to be relubricated during operation if required.The bearings are sealed on both sides.The low friction contact lip seal runs in a groove in the inner ring.This gives excellent sealing characteristics,while minimising torque and heat generation.

BSF Series :

The BSF series of the bearings are with an extended outer ring ,with bolt holes for easy direct mounting .Relubrication holes in outside surface and face of the outer ring allow for relubrication during operation if required .The holes are closed off with set screws, An extraction groove on the outer surface of the outer ring aids removal of the bearing. Both the BSN series and BSF series are designed to meet the modern machine ‘s requirements that can position a work position quickly and efficiently.
