Modular electrical linear drives OSP-ELubricating the spindle of linear drive OSP-E..SBR and OSP-E..STR• Remove the motor / drive unit from the drive shaft (1).• Move the piston rod (29) by hand into the extended position.• Release the countersunk screws (4) and clamping piece (5). Lift the cover band (14).• Dispense a continuous string of grease on to the threaded spindle (13) and the inside of the tube (22)).• Move the piston rod (29) by hand several times through the complete stroke.• Reposition the cover band (14). Put the clamping piece (5) back into place and insert the counter-sunkscrews (4), tightening them to the appropriate torque.• After the lubrication the motor / drive unit is ready to be mounted again.Thread sizeM 3M 4Tightening torquescountersunk screws0,5 ± 0,1 Nm2,2 ± 0,1 Nm8.3.3 Check axle backlash of drive spindlesInspection of the axle backlash of the drive spindles• The axle backlash of the drive spindles is determined by axially moving the carrier (1)(OSP-E..SB / OSP-E..ST) and/or the piston rod (2) (OSP-E..SBR / OSP-E..STR) at machine standstill.The determined clearanceshould not exceed:• OSP-E..S 0.2 mm• OSP-E..ST 0.5 mm• OSP-E..SBR 0.2 mm• OSP-E..STR 0.5 mmAttentionIf the allowable backlash clearance isexceeded, the spindle nuts and/or thespindles must be replaced.8.3.4 Replacing the spindle nut / spindleOSP-E..SBLinear drive with ball screw drive and internal plain bearing guideInformationThe exchange of the ball screw spindle requires perfect coordination. The ball screw nut must be adjustedprecisely in order to avoid premature wear due to faulty installation.The spindle must only be repaired by Parker-Origa GmbH or separately instructed personnel.30
