Similar to the QSZ, the QSZE is driven by an trapped linear belt that can be adjusted to reduce lash and is driven along a single internal profile rail. This unit consists of a square aluminium profile with an integrated roller guide and is covered by a stainless steel sheet (thickness 0.37mm, material 1.4301). The pulleys have maintenance-free ball bearings. Belt tension can be readjusted by a simple screw adjustment device in the carriage.
The QSZE is ideal for applications in clean rooms with a clean-room classifications of 1.000 (corresponding to US Fed. Standard 209 E).
