Clamps for Open-Ended Timing Belts

clamp image thumbnailClamps are used to attach the ends of an open-ended timing belt. For best clamp performance we recommend at least 5 teeth in mesh.

Note: Pretension cannot be applied with clamps. If you require the ability to apply pretension, then please refer to our section on Tensioning Clamps. We offer additional options for connecting open-ended timing belts that may also suit your needs.

Contact an applications engineer or see our information on Connecting Kits.

BRECOflex clamps are made to mesh perfectly with our timing belts.  We are a single source supplier for all of your belting and drive component needs.

Please select your belt pitch from list below to see the specs and part numbers for our stock clamps.
