COVID-19 (Coronavirus) update: Whilst we are continuing to ship customer orders, same day dispatch is not guaranteed. Lead times for out of stock / back order and non-stocked items are increasing due to our suppliers operating with reduced staffing levels. International deliveries - please allow extra time for your order to arrive with delays in the transport network worldwide. Some countries have suspended their internal postal system so please check with your local postal service before ordering. Royal Mail is unable to guarantee its UK Next Day Special Delivery service.
A 2.5mm diameter 'O' ring with an internal diameter of 30mm. Made from Nitrile (NBR N70) rubber which is ideal for use as a drive belt on our wooden, plastic and aluminium 'V' pulleys. Suitable for use up to 70 Deg C.
Common practice is to slice the belt to length with a sharp knife ensuring the cuts are at 90 degrees and then glue using a cyanoacrylate adhesive (superglue). There is some stretch in the belts depending on the length but not too much.
