Timing-Belt Reverse Unit 8 80 R25 mounted at a profile height of 40 mm in the groove of Profile 8 using Universal Fastener 8 and special T-Slot Nut or at a profile height of 80 mm by splitting the special T-Slot Nut at the specified break point.
The variation in the emergence dimensions from 80 mm to 40 mm is achieved by rerouting the Timing Belt internally. The Timing Belt is routed with its smooth reverse side over the reversing pulleys. The allowable driving torque of Timing-Belt Reverse Units 8 80 R25 is limited to M D = 40 Nm when the loaded belt runs through the reversing pulleys. In this case, a Timing-Belt Reverse Unit 8 40 R25 can be used as a second reverse unit.
To protect the Timing Belt against damage, the profiles must be rounded at the joint to the Timing-Belt Reverse Unit.
