B3W Actuators

B3W linear belt drive actuators have an enclosed ball bearing design for heavy loads, high bending moments, and long service life.

New Capabilities: Stroke Lengths 400 inches +

The B3W linear belt drive actuator is capable of accommodating heavy loads and handling high bending moments with consistent, smooth operation. B3W linear belt drive actuators incorporate an enclosed recirculating bearing system eliminating the need for external load guidance. The B3W linear belt drive actuator delivers repeatability and 100% duty cycle with long service life.
