Sealey SJBEX.A01 Bearing Mounts for Viking Jacking Beams

Flat arm with spring loaded roller bearings for use with SJBEX3000S and SJBEX4000S Jacking Beams. When unloaded these arms support the weight of the beam, allowing for it to run smoothly along the pit edge. In position, and when the beam is under load, the bearings retract, to leave the flat of the arm, to stabilise the lift.
