Belt Driven Modular Linear Actuators

Belt Driven Actuators in Almost Any Length

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 tensioning is required. The pulleys have maintenance free ball bearings. Belt tension can be readjusted by a simple screw adjustment device in the carriage. Belt driven modular actuators can also be used for symmetrical motion of two or more linear units running parallel.

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

External Belt Driven

The carriage, using an external linear belt, is driven along an external linear guide rods and ball bearings that can be adjusted to remove lash. This provides a low friction smooth linear movement.

Internal Belt Driven

The carriage is driven by an internal linear belt that can be adjusted to reduce lash is driven along the external roller bearings These units are ideal for applications in clean rooms with a clean-room classifications of 1.000 (corresponding to US Fed. Standard 209 E). This arrangement allow for easy adjustment and belt tensioning, which can be readjusted by a single screw adjustment device in the carriage. The pulleys have maintenance-free ball bearings.

V Groove Guided

The carriage, using an external belt, is driven along the V-guides for smooth linear movement. The V-guides provide an excellent maintenance free linear guide when dirt and debris is a concern.

Internal Roller Bearing Guided

The carriage is driven along an internal linear guide rods and ball bearings that can be adjusted to remove lash. The linear belt drive is either trapped, exposed, or internally driven. The QLZ and QLZE are ideal for applications in clean rooms with a clean-room classifications of 1.000 (corresponding to US Fed. Standard 209 E). The openings of the DLZ and DLVZ guide body are sealed with 3 stainless steel cover bands to protect the guide from splash water and dust. Alternatively, the opening can also be covered with a bellow or can be delivered without cover bands.

Internal Profile Rail Guided

The carriage moves along linearly guided by an internal profile rail for high rigidly. The linear belt drive is either trapped, exposed, or internally driven. The openings of the DSZ and DSSZ guide body are sealed with stainless steel cover bands to protect the guide from splash water and dust. Alternatively, the opening can also be covered with a bellow or can be delivered without cover bands.
