Ondrives GT Pulleys & Belts

Synchronous timing pulleys and belts in extra small sizes are one of the latest addition to the recently extended power transmission product range introduced by gearbox experts, Ondrives Ltd.

These pulleys and belts are special in that they are much smaller than the usual sizes and pitches available as standard for those applications where a small envelope space is required. Sizes start at just 1.5mm pitch to suit a 3mm belt width going up to 2.5mm pitch to suit a 6mm belt as standard.

These synchronous pulleys are backlashless, backlash per tooth is 0. They are ideally suited to small precision instruments and the specially coated belt is ideally suited for low particle generation as the rubber powder is not spread. A socket head cap screw comes with all these pulleys as standard and recommended dimensional deviations for pitch diameter are h6 and h7. Bore and keyway modifications are available on request. Complete specials are also available where required, but may be subject to a minimum order quantity.

Ondrives offer these miniature versions of pulleys and belts alongside the more standard pitch and belt width sizes seen in everyday usage, so every application is catered for.
