Internal Box Section Sliding Gate Wheel 100mm, V Groove

A 100mm V groove wheel that sits inside a box section rail, for sliding gates on V ground track. Choose this wheel when you want a clean rail with no bracket showing. The wheel goes up inside the bottom rail through a slot, with two foot flanges bolting to the underside. Only the base of the wheel shows, 27mm below the mounting face on the data sheet. It is listed at 100mm and given as 98mm, with a 17mm V groove for V section ground track, and the foot is 152mm long with two 8mm holes at 126mm centres. The price shown is for one wheel with its bracket, with a minimum order of 5.

Important: This wheel runs on V section ground track only. It will not run correctly on round bar or in a cantilever track. Data sheet sizes are a guide; components can vary slightly.

Why this wheel works

A V groove keeps the gate on line. The V sits astride the ridge of V section ground track, so the wheel centres itself as the gate travels and the sloping faces stop it wandering off the crown. That is why a V wheel needs V track and nothing else.

A simple running gear. This line is not listed as double bearing, which keeps the price down for a gate opened by hand a few times a day. Choose a double bearing wheel if the gate is motor driven or in constant use.

Mostly hidden, and low to the ground. With only 27mm of the 98mm wheel below the mounting face, the rail sits much closer to the track than it does on a bracket wheel, which needs 104mm. About 71mm of the wheel rises up inside the rail, so check the height inside your box section first.

Where it is used

New sliding gates in box section rail on V ground track, where a tidy line along the bottom of the gate matters. The rail needs a slot cut in its underside and enough internal room for the wheel and its 33mm wide bracket. It is not for cantilever gates.

Specifications

Choosing the right wheel

If your rail cannot take a slot, or you are retrofitting a finished gate, use the external 100mm V wheel, which bolts under the rail with no cutting. The 140mm and 80mm internal wheels in this range run on 20mm round bar, not V track, so they will not suit this track. Check your rail for internal height before ordering: it must clear at least 71mm plus the bracket.

Fitting and care

Cut a slot in the underside of the rail, long enough to clear the 152mm foot and wide enough for the 33mm bracket. Check that the section is deep enough to clear about 71mm of wheel above the mounting face. Offer the wheel up from underneath and bolt the two foot flanges to the rail through the holes at 126mm centres. Fixings are not listed as included, so allow your own. Leave no sharp edges on the slot, and paint any bare steel.

Keep the track clear of stones and packed dirt, and check the wheels and fixings at each service. Plating gives light protection only, so touch up scratches and welds with zinc-rich paint. Replace a wheel that has worn or stiffened, and check its partner at the same time.
