B3S Ball Screw Linear Actuators

B3S ball screw linear actuators have an enclosed ball bearing design that accomodates heavy loads, high bending moments and delivers long service life.

The B3S ball screw linear actuator is capable of accommodating heavy loads and handling high bending moments with consistent, smooth operation. B3S ball screw actuators incorporate an enclosed recirculating ball bearing system that eliminates the need for external load guidance. The B3S ball screw linear actuator delivers repeatability and 100% duty cycle with long service life.
