Sliding Door Wheels, Rollers & Tracks

If your slider grinds, jumps or takes two hands to open, the problem is usually worn sliding door wheels or a damaged track rather than the door itself. AluminiumDoor.co.za is a free quote-request service. Describe your door and we pass your request to an independent supplier or fabricator in your area who stocks a matching roller for sliding door panels, plus rails and tracks. They quote you directly, with no obligation. DIYers can collect the parts, contractors can order in bulk, and fitting can be arranged if you would rather not lift the panel out yourself.

Signs your rollers or track need replacing

The door drags, grinds or squeals when it moves
The panel has dropped and the lock no longer lines up
Wheels are flat, cracked or no longer turn freely
The bottom track is dented, worn through or filled with grit
Daylight or draughts show under the panel

Dust, Highveld grit and sea sand all speed up wear, so cleaning the track regularly helps new rollers last.

Rollers, wheels, rails and tracks

Most aluminium sliders run on a pair of rollers in each panel. These come with nylon or steel wheels, single or tandem, and with sealed ball bearings in better grades. Heavy glass panels and large stacking doors need tandem or heavy-duty rollers. The rail for sliding door panels, often called the sliding door track, can be a clip-on cap over a worn sill or a full replacement section in aluminium or stainless steel.

Matching the right aluminium door wheels

Aluminium door wheels are not universal. The housing size, wheel diameter, track profile and adjustment screw position differ between system ranges. Take the old roller out if you can and measure it, or send photos of the panel end and track. A supplier can match it from stock or suggest an adaptable roller.

Adjusting and fitting

Most rollers have an adjustment screw that raises or lowers the panel so it runs level and locks properly. Replacing them means lifting the panel out, which is heavy with safety glass, so many people ask for fitting to be arranged. Cost depends on roller grade, number of panels, track replacement and call-out.

Comparing sliding door rollers and tracks prices

Prices for aluminium door parts change with profile, brand, finish and quantity. When quotes arrive, check:

Fit: that the part matches your door's system and profile; a photo or a sample of the old part helps.
Finish and material: colour match, and stainless or marine-grade components for coastal sites.
Fitting and delivery: whether fitting, adjustment or delivery is included in the price.
Trade terms: bulk pricing for builders and fabricators, and account options.

What to include in your request

Photos of the panel end, old roller and bottom track
Roller length, width and wheel diameter if you can measure
Panel size, glass type and how many panels slide
Whether you want the parts only or fitting as well

Frequently asked questions

Can I replace sliding door rollers myself?

Yes, if you can safely lift the panel out of its track with a helper. Glass panels are heavy, so if you are unsure, ask for fitting in your request and it can be arranged.

How do I know which roller fits my door?

Remove an old roller if possible and note its length, width, wheel diameter and the position of the adjustment screw. Photos of the panel end and track help a supplier match it.

Can a worn track be repaired instead of replaced?

Often. A clip-on stainless or aluminium track cap can be fitted over a worn sill, giving the new rollers a smooth surface without removing the whole frame.

Why does my sliding door still drag after cleaning?

The rollers may be worn or the panel may have dropped out of adjustment. Turning the adjustment screws may help; if the wheels are flat or seized, they need replacing.
