Practical guide
How to choose the correct version
A suitable replacement cannot be identified by appearance alone. Compare the designation, dimensions, design and operating conditions.
What to compare before ordering
- technical designation and manufacturer
- dimensions, tolerances and mounting method
- material, version and critical parameters
- operating environment and assembly compatibility
Send a photo of the tread profile and mounting so we can distinguish between track, guide and tension rollers.
