Double Bearing Sliding Gate Wheel 120mm, V Groove, M16 Bolt-Through Axle

A 120mm double bearing wheel for a sliding gate running on V section ground track. The wheel is 118mm measured, with a V shaped groove 20mm across and a rim 30mm wide. An M16 threaded axle bolt, with its nuts, comes with the wheel, so you fix it by bolting through the side of a channel or bracket under your gate's bottom rail. It has a double bearing, so the load on the axle is shared. No load rating is published for it, so match it to a gate of known weight or call us before you order. The price shown is for one wheel, with a minimum order of 6.

Why this wheel works

The largest V wheel with a double bearing. At 118mm measured with a 30mm rim and an M16 axle, it has more rim and more axle than the 100mm V wheel, for a larger gate on V track.

The groove holds the line. The V shaped groove seats on the track and keeps the wheel from wandering, so the gate runs straight along the V.

Two bearings on the axle. The double bearing shares the load between two bearings rather than one.

Bolts straight on. The M16 axle bolt goes through the side of a channel or bracket and is held with its nut, so you can fit and replace it without welding.

Plated against rust. The wheel and bolt are yellow zinc plated, not hot-dip galvanised.

Where it is used

Larger sliding gates on V section ground track, at bus and vehicle depots, industrial estates and busy commercial yards. It suits a new heavy gate built to run on V track, and it replaces a worn 120mm V wheel on the same track.

Specifications

Choosing the right option

Choose the groove first, because it must match your track. Then the fixing, then the diameter: a larger wheel rolls over grit more easily but needs more room under the rail.

Stepping down, the 100mm double bearing V wheel has an M14 axle and a 25mm rim, so that is the one for a mid-sized gate. This 120mm wheel is the step up, with the M16 axle and 30mm rim. Our other 120mm V wheel has the same diameter and groove, without the double bearing. If your track is round bar, you need a round groove wheel instead: this V groove will not seat on it.

Fitting and care

Lay the track first, straight and level. Most sliding gates run on two wheels, set about a fifth of the gate length in from each end. Fix a channel or a bracket under your bottom rail and bolt the wheel through it, so the M16 axle bolt is supported on both sides of the wheel where you can. The axle is M16 and the wheel and bolt measure 84mm long over the bolt, so check the channel or bracket can take a 16mm bolt and allow for the 30mm rim. Check the gate runs its full travel without binding before you tighten up fully.

Keep grit and leaves off the track, because that is what wears a wheel. Check the axle nuts and that the wheel runs freely at each service.
