FAQ

How can you recognise a worn pulley groove?

If the bottom of the groove is shiny, the belt has bottomed out and no longer wedges against the flanks - the pulley needs replacing. Profile gauges are used for checking.

How does excessive belt tension affect the bearings?

Excessive radial force puts high loads on the bearings, leading to overheating and premature failure. The correct tension is specified by the belt manufacturer.

Do you ship pulleys from stock?

The stock level is shown above the price and may vary depending on the warehouse.

What materials do you use for pulleys?

Cast iron dampens vibrations excellently, is resistant to abrasion and dissipates the heat generated by belt friction very well - ideal where quiet and stable drive operation matters.
