Nylon Sliding Gate Wheel 100mm (98mm Actual), 20mm Round Groove, M12 Bolt-Through Axle

A plain white nylon sliding gate wheel, sold as 100mm and measuring 98mm, on an M12 threaded bolt. There is no bracket: the bolt passes through the side of a fork or channel that you weld or fabricate under the gate's bottom rail, and the wheel runs between the two sides. It runs on a 20mm diameter ground track, such as our 20mm galvanised sliding gate track. The wheel is 26mm wide with a 21mm groove opening and the bolt is 68mm long overall. No load rating is published for this 100mm round-groove 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

Your fork, your height. You make the fork yourself, so you set the ride height, and the wheel can be changed later by undoing one bolt.

Simple to replace. Where a fork already exists, a new wheel is a bolt-out, bolt-in job with no drilling into the rail.

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

Fabricated sliding gates where the wheels sit in a welded fork or a section of channel under the rail, at workshops, compounds and small yards. It also replaces a worn wheel of the same size in an existing fork, provided the fork clears the wheel width and the hole matches the bolt.

Specifications

Choosing the right wheel

Start with the track, because the groove decides everything else. This wheel has a 20mm round groove with a 21mm 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 19mm opening.

Against the smaller size. The 80mm wheel measures 78mm rather than 98mm and comes on an M10 bolt, 62mm long overall, where this one has an M12 bolt, 68mm long. Your fork has to be drilled for the bolt you buy. The smaller wheel keeps the rail lower.

Against the other fixings. In this size and groove, the stainless bracket bolts up under the rail and stands 104mm from plate to wheel base, while the internal housing hides inside a box section rail and shows only 27mm of wheel below the tabs.

Fitting and care

Finish all welding before the wheel goes near the fork, because heat distorts nylon. Drill the fork for an M12 bolt, fit the bolt through the fork and the wheel, make sure the fork clears the 26mm wheel and its hub spacers, and tighten the nut so the wheel turns freely. Roll the gate through its full travel before you finish.

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.
