They must be subjected to the loading and speed conditions specified in the catalog. Modification of parts of the actuator or replacement of components with different and non-original parts is not permitted. The replacement of components with original spare parts is carried out only by Servomech S.p.A.
4.1.2 Standard operating conditions The actuator must be used in an environment whose conditions comply with the provisions of Servomech S.p.A. The works necessary for obtaining and maintaining that conditions are in charge of the owner and, where applicable, are in charge of the end user.
MAKE SURE THE SAFETY PROTECTION OF THE MACHINE (MECHANICAL AND ELECTRICAL) ARE ACTIVE. DURING OPERATION, TEMPERATURE OF THE EXTERNAL SURFACE OF MOTORS CAN REACH HIGH TEMPERATURES. HOT SURFACES ON ACTUATOR CAN CAUSE BURNS AND SHOULD NOT BE TOUCHED. Servomech S.p.A. 16.30-40-50.E - Rev. 01 DD (M/Y) 05/19...
It is therefore necessary to verify the difference between the two positions, by direct check or asking SERVOMECH, to evaluate the compatibility with the application requirements. The switch FC 3 is supplied with normally CLOSED contact (NO contact on request) already wired with a multicore cable 2 ×...

STROKE END LIMIT SWITCHES MUST BE CONTROLLED TO BE SURE THAT THE ACTUATOR STOPS BEFORE THE MECHANICAL STROKE END LIMITS. IN CASE THIS HAPPENS, THE ACTUATOR CAN BE LOCKED AND THE INTERNAL COMPONENTS CAN BE DAMAGED. Servomech S.p.A. 16.30-40-50.E - Rev. 01 DD (M/Y) 05/19...
IF THIS HAPPENS, THE RELATION BETWEEN AXIAL POSITION OF PUSH ROD AND SWITCHES SETTING WILL BE LOST. IF A WRONG ACTION OCCURS, OR IN CASE OF DOUBT, PLEASE REPEAT THE SET UP OF THE LIMIT SWITCHES FOLLOWING THE SET-UP INSTRUCTIONS BELOW. Servomech S.p.A. 16.30-40-50.E - Rev. 01 DD (M/Y) 05/19...

Fix the threaded element with Loctite 270. To unmount the element, heat the threaded area to unlock it. Unscrew the fitting element counterholding the torque with a wrench flat on the rod end. Servomech S.p.A. 16.30-40-50.E - Rev. 01 DD (M/Y) 05/19...
7 COMMISSIONING AND USE SERVOMECH linear actuators are supplied lubricated and ready to be used. Before to start commissioning and activation, the following checks must be carried out: Shifting direction check Check if the push rod shifting direction is compatible to the indications on the control unit, by powering the electric motor on VERY BRIEFLY.
8 LUBRICATION SERVOMECH linear actuators CLA/CLB series are supplied lubricated, with lubricants indicated in the table below. ACTUATOR GEARBOX LINEAR DRIVE PUSH ROD GUIDE CLA 30 Grease (NLGI 0 DIN 51818): Grasso (NLGI 2 DIN 51818): ENI Grease MU EP 0...
Every 2 months time interval: visual inspections of actuator conditions, cleaning of dirty parts of the actuator. In case of lubricant leakage, contact SERVOMECH. ACTUATOR Lead pitch Lubrication Linear drive – Q.ty of lubricant Push rod guide...
Apply the grease quantity indicated in Tab 9.1. Extend and retract the push rod over its entire stroke for 3 full cycles. If necessary, remove excess of lubricant from push rod. Servomech S.p.A. 16.30-40-50.E - Rev. 01 DD (M/Y) 05/19...
