POM flat-belt bearing pulley with an 8mm bore, 32mm outer diameter and 12mm thickness. Designed for minimal noise, low vibration and straightforward replacement use.


Quiet operation – thanks to POM construction

POM is a low-friction engineering plastic with a smooth surface that reduces contact noise and helps dampen vibration during rotation. The material's properties limit squeal from belts and shafts under light to moderate loads.

Run lines, skates and hobby mechanisms with noticeably less noise, useful where quieter operation matters.

Consistent rotation – with metal bearing and precise dimensions

A metal inner bearing combined with an accurately machined 8mm bore and 32mm outer diameter keeps concentric rotation and reduces wobble. Tight tolerances help maintain tracking under continuous rotation.

Stable tracking reduces misalignment and helps extend belt and axle life during regular use.

Easy maintenance – thanks to pack of four and standard sizing

Sold as a set of four, each pulley matches common 8mm shafts and 32mm housings for quick swap-outs without special components. Standard sizing avoids bespoke parts and speeds up routine servicing.

Keep spares on hand for fast on-site replacements and reduce downtime during repairs or maintenance.
