The carriage is driven by an internal linear belt with a vertical drive mount that can be adjusted to reduce lash and is driven along the external roller bearings. The pulleys have maintenance-free ball bearings. Belt tension can be readjusted by a simple screw adjustment device in the carriage.

Since the ELVZ has an internal belt the unit is suitable for applications in clean rooms for clean-room classifications 1.000 (US Standard 209E).

ELVZ Actuators are available in multiple configurations;

• Single Carriage
• Single Wrap Around Carriage (WAC)
• Dual Carriages
• Dual Wrap Around Carriages (WAC)
