SPM⁺ / TPM⁺ endurance

Name: SPM+ / TPM+ endurance
Brand: WITTENSTEIN group

Servo actuator

The SPM⁺/TPM⁺ endurance servo actuators are customized actuators with liquid cooling for maximum efficiency, high power density and the shortest cycle times. Thanks to a flexible modular system, various gearboxes can be integrated to match the motors. The highly compact design opens up enormous degrees of freedom in the design and enables you to downsize your machines thanks to maximum power density.
