Special features
4.3
Mechanical overload protection
The actuator contains a mechanical overload protection unit (clutch).
This overload protection unit will activate if the linear unit of the
actuator overloads. This activation will protect the motor and gear
unit from being damaged.

description
Motor
The motor is a 12 or 24 V DC. The motor’s shaft powers a spur gear.
The lift speed depends on the load. The motor unit is surrounded by
metal housing. The metal housing cannot be opened.
Gear unit
The spur gear is directly powered by the motor shaft which moves a
trapezoidal sliding spindle.
Linear unit
The actuator extends and retracts the push tube. The linear unit is
surrounded and protected by the guiding tube. The push tube of the
actuator is connected to the spindle with a ball screw nut.
The linear unit is connected to the motor with several screws.
These screws should not be loosened or removed.
Continued operation of the clutch can result in overheating and
damage to the linear actuator. If clutch activates, switch off
power immediately.
C A U T I O N
Clutch activation can cause the limit switch to stop functioning.
If this happens, have an SKF engineer adjust it so that it again
operates properly.
C A U T I O N
Incorrect activation of clutch could cause actuator damage.
Limit stroke of linear actuator using internal/external limit switch
or other electrical component.
