Linear Actuator

Linear Actuator

The leadscrew-driven Kerk provides an electromechanical alternative to pneumatic actuators. The actuator can be precisely moved to any position and speeds can be varied within the stroke. The maintenance-free actuator requires no lubrication. The unit uses Kerkote TFE coating and Kerkite high-performance composite polymers in combination with precision leadscrews. The actuator accepts NEMA Size 17, 23, and 34 motors.
