Roller Profile

These are concave rollers — the tread is grooved so the wheel sits down over a rounded or raised track rail and holds the door centred as it runs. Match the profile to the track you already have: a concave wheel will not track correctly on a rail shaped for a flat or V roller. The roller reference guide in the gallery shows all six profiles side by side so you can identify yours before ordering.

Installation Tips

• Check the track before you fit. File any burrs or flat spots smooth — a damaged track will chew out a new roller within weeks.
• Clean all grit and old grease out of the track. Grit is what kills a roller, not load.
• Replace carriages in pairs. A new roller running against a worn one carries uneven load and both wear out early.
• Match the new roller to the old one for wheel diameter and profile — concave, convex, V-groove or flat.
• Check the axle or hub matches too — same diameter, same length and the same fixing type as the roller you removed.
• Slide the door through its full travel before refitting stops or screens.

Care & Maintenance

• Use a dry lubricant only — silicone or dry PTFE. Oil and grease hold dust and grind the roller.
• Sweep the track out every few months, more often in coastal or dusty areas.
