Nylon Sliding Gate Wheel 80mm (78mm Actual), 20mm Round Groove, Stainless Top-Fix Bracket

A white nylon sliding gate wheel, sold as 80mm and measuring 78mm, with a round groove and a stainless steel exterior bracket. The bracket is a formed channel with a flat top that fixes up under a box section bottom rail, so the wheel hangs below the rail on the track. It runs on a 20mm diameter ground track, such as our 20mm galvanised sliding gate track. The bracket is 100mm long and 33mm wide with 12 x 9mm slots on 70mm centres, and it stands 85mm from the top plate to the bottom of the wheel. No load rating is published for this wheel, so treat it as having no stated rating. The price is for one wheel, with a minimum order of 6, and most sliding gates run on two.

Why this wheel works

Quick to hang. The bracket comes assembled with the wheel, so there is no fork to make. Drill two holes in the underside of the rail and bolt it up.

Stainless where it matters. Ground level is where gate hardware fails first. A stainless steel bracket copes with standing water better than plated steel.

The round groove follows a 20mm section. The curved groove matches a 20mm diameter ground track, so the wheel stays centred. Measure your track before ordering, because the wheel will not seat on a smaller or larger section.

Quiet, and it will not rust. Nylon runs quietly on a steel track where a steel wheel can rattle, and it needs no painting. It is softer than steel, so grit and shock loads wear it faster, and it is not the choice for a heavy gate.

Where it is used

Lighter sliding gates on box section rails: side passage gates, small yard and compound gates, and hand-pushed gates at the edge of a commercial site, where a neat bolted-on wheel suits better than a welded fork. Check the hole centres if you are replacing a wheel.

Specifications

Choosing the right wheel

Start with the track, because the groove decides everything else. This wheel has a 20mm round groove with a 22mm opening at the rim, so it needs a 20mm diameter ground track and will not run on an inverted-V ground track or flat bar. For an inverted-V ground track, choose the V groove version, which has a 18mm opening.

Against the larger size. The 100mm wheel measures 98mm rather than 78mm. Its bracket is 130mm long and 36mm wide against 100mm and 33mm here, it stands 104mm from the top plate to the bottom of the wheel rather than 85mm, and its fixings are 9mm round holes on 105mm centres rather than 12 x 9mm slots on 70mm centres. A bigger wheel rolls over stones and uneven track more easily, but it raises the gate.

Against the other fixings. In this size and groove, the internal housing hides inside a box section rail and shows only 27mm of wheel below the tabs, while the bare wheel on an M10 bolt goes in a fork you make yourself.

Fitting and care

Fix the track first, straight and level. Stand the gate on blocks with the wheels on the track, mark the bracket positions, and fix each bracket through its two slots, which give a little movement along the rail with bolts sized to suit. Do not weld the bracket with the wheel fitted, because heat distorts nylon. Roll the gate through its full travel before final tightening.

Keep the track swept, because grit is what wears a nylon wheel. Check for flats and groove wear at each service and renew the wheels in pairs.
