Belt drive

Function:
This unit consists of a square aluminium profile with an integrated roller guide. The carriage is driven by a timing belt. Each standard pulley
includes one coupling claw on one side. Belt tension can be readjusted by a simple screw adjustment device in the carriage. This device can
also be used for symmetrical adjustment of two or more linear units running parallel.
This linear unit is suitable for application in clean rooms of clean-room classification 1.000 (corresponding to US Fed. Standard 209 E).

As required. Max. length 6.000 mm without joints.
By T-slots.
By T-slots and mounting sets. The linear axis can be combined with any T-slot profile.
HTD with steel reinforcement, no backlash when changing direction, repeatability ± 0,1 mm.
In the standard version, the carriage runs on 4 rollers which can be adjusted and serviced at a central servicing position.
For longer carriages the number of rollers can be increased.
