Continuous Duty Cycle Mechanical Screw Jack Actuator

Continuous Duty Cycle Actuators are specifically designed for continuous operation.

The gear set operates in an oil filled bath for thermal efficiency and long life.

The shell is made of a finned aluminium for better cooling properties.

Additionally the ball screw system increases the efficiency of these models.

Continuous operation (at rated capacities only).
Increased predictable life.
High mechanical and thermal efficiency.
Oil Lubricated.
