Linear crossed roller bearings may need to be re-tensioned if the stage plates are disassembled or become loose for any reason. The procedure is the same for any stage. The instructions will refer to the parts on the LS-50 stage shown below. The principles apply to all crossed roller stages.
This completes the stage bearing preload procedure.
Maximum torque rating for the Screws used on the LS50 is 1.8 N-m or 17in/lbs. Excessive torque will lead to stripped the screws and irreversible damage to the unit. Suggest using a Torque wrench/screw driver like the one shown below.
