What the PULLEY WHEEL does
Rollers, pulleys and wheels carry and route movement in the feed system — supporting the drifter along the beam and guiding the feed chain, rope or hose. They run in dust, water and cuttings for their whole life.
Signs it needs replacing
- Flat spots, grooving or chipping on the rolling surface
- Seized rollers that slide instead of turning
- Bearing noise or play
- Chain, rope or hose wearing unevenly against the roller
Before you fit it
A seized roller wears whatever runs over it very quickly, so replace it as soon as it stops turning freely. Check its bearing and seal rather than only the outer surface.
General guidance for this class of component. Always work to the torque figures, clearances and service intervals in your machine's own manual.
