Belt Driven Modular Linear Actuators

Designed for high speeds with long distances. Perfect for fast positioning and handling tasks with low maintenance requirements.

Belt Driven Modular Actuators have a distinct advantage due to their ability to be manufactured in virtually any length. Belt drive actuators models include either an external, trapped, or internal belt arraignments. The Belts are made of a high tension steel material that only requires a single adjustment after initial use. No further tension is required. The pulleys have maintenance free ball bearings.

The belts can be supplied for clean room and explosion proof environments.
