291-ESK
BERG ESK Tool Clamping Cylinders
The electro-mechanical actuator is specifically designed for actuating the SSK gripper. This device generates both the clamping force, adjustable throughout a wide range, as well as the higher release force required for tool ejection. Up to a spindle rotational speed of 4000 rpm, the ESK clamping actuators are advantageous whenever the disadvantages of spring clamping are to be avoided and high clamping forces at relatively low rotational speed, as well as rigid spindle constructions are required. For their function they only require electrical energy which is available virtually everywhere.

For their function they only require electrical energy which is available virtually everywhere.
Design FeaturesThe electro-mechanical actuator ESK comprises the proven assembly groups: three-phase brake motor, collector ring power supply, planetary gearing, detent clutch with helical gearing which clamps the tool shanks with the workspindle in a self-locking manner. Electrical energy is only required for clamping and release. Proximity switches allow automatic control of the device. The spindle drive is not released until the clamping force and clamping position have been attained.
