Before ordering, please read the following carefully
The ideal installation for any machine tool - especially high-speed drives - is a Swiss-manufactured Betalon-Multiply belt - made either endless or supplied as a DIY kit length with the ends scarfed and glue and instructions supplied. The glue is a very special type and supplied with each order where you need to assemble the belt on the machine. The resulting joint is smooth and tremendously strong.
These belts are light in weight but immensely strong and stretch resistant. They absorb shock loads well, have a high coefficient of friction, enjoy a proven record of reliable industrial service and can be made in almost any combination of length and width. Of course, if the belt is made for you as a loop, as with an ordinary V-belt, you may have to dismantle pulleys, etc., to fit it, but the trouble taken will be well worthwhile as the drive to your machine will be quieter, smoother and much more reliable.

When you order a DIY kit, you must measure the "finished length" needed very carefully.
Don't add anything for the overlap - we take care of that.
What do we mean by "finished length"?
It means the length of the belt cut, laid flat on a table and measured from one end to the other, but don't just measure the old belt - it will probably have stretched.
- To measure a flat belt, run a dress-maker's tape or a long strip of paper around the pulleys. If two people measure independently, mistakes are less likely).
Most - but not all - belt-drives have a tensioning mechanism. As all types of belt stretch slightly in service, before measuring set any adjustment so that the pulleys are nearly, but not quite, as close together as possible. Click here for additional detailed advice on finding the right length.
Width: In general belts can be to the full width of the pulley less 2 mm - but if the pulley has flanges reduce the belt width by 4 mm to allow a small gap at each side (if the edge of the belt touches the flange, it will try to ride up it). If in doubt about any aspect of this (we also supply belts in other materials) just phone 01298-871633 (09:00 to 23:00) for advice. On overseas sales there is no 20% sales tax to pay.
