Ondrives' 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 1.5 mm pitch to suit a 3 mm belt width going up
to 2.5 mm pitch to suit a 6 mm 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.
