Metric Pitch Pilot Bore Timing Pulley: These premium quality pulleys are manufactured from aluminium 6082 to exacting standards.

The efficiency of drives can be affected by the use of worn pulleys and belts. Periodic inspections for debris and belt damage are recommended, replacing where needed, in turn, optimal drive efficiency as well as increased uptime and reduced running costs for your equipment can be achieved.
