  • Page 30: Relubrication Intervals

    For a servo actuator use under nominal performances and standard environment conditions, the lubricating time interval is set to 10 ball screw rotations. In case of heavier or particular working conditions, please contact Servomech S.p.a. to evaluate different lubrication interval. Following table gives all lubricating information for all sizes and versions available.

  • Page 31: Removal And Replacement

    8 Removal and replacement Servo actuator components may only be dismantled and replaced by Servomech. The only exception to this rule is the disassembling of the motor. The disassembling procedures are described in following sections. 8.1 SA IL – Disassembly of the motor Power transmission between motor and ball screw is made by a coupling.

  • Page 32: Sa Pd - Disassembly Of The Motor

    Power transmission between motor and ball screw is made with a timing belt. To disassemble the motor see the following work steps. Figure 8.3 – SA PD disassembly of the motor  Remove the plugs (10), the screws (9) and washers (8).
  • Page 33 To remove the motor pulley please see the following work steps. Figure 8.4 – SA PD disassembling of the motor pulley  Loosen the locking screw (16) of the pulley (15). React the torque using a wrench on the motor shaft in the area behind the pulley (14).
