Garage Door Rollers & Wheels Perth

Nylon rollers run quieter than steel and do not rust, which matters near the coast. They come in standard and long-shaft versions — the long shaft is used on the top section of a sectional door and on low-headroom installations, so check which one you are replacing before ordering.

The symptoms of worn rollers are hard to miss: grinding or rumbling as the door moves, a door that judders instead of gliding, and flat spots you can feel by turning a roller in your fingers. In a bad case the roller stops rotating altogether and drags along the track, which wears the track itself.

Transfer pulleys carry the lifting cable on tilt doors and come in plastic and steel. A seized pulley frays the cable that runs over it, so a pulley that no longer spins freely is worth replacing before it costs you a cable as well.

Rollers are usually replaced as a full set. Mixing new and heavily worn rollers leaves the door running unevenly, and the labour is the same whether you change two or ten.
