Especially in older sewing machines, the drive belt is a component that suffers very heavy wear and must be replaced regularly. Therefore Prym supplies as an important spare part a 5 mm thick round V belt with a 300 mm circumference and a diameter of 100 mm. So, most older sewing machine models are helped to come back to a useful life without great effort. The Prym V belt is made from sturdy black rubber, has a very high elasticity and durability and brings swing back in the good old sewing machine.
