Double Bearing Gate Wheel with Weld-On Plates 80mm, 20mm Round Groove

An 80mm wheel with weld-on side plates, for a sliding gate running on a 20mm round bar ground track. The wheel is 78mm measured and runs on a double bearing, with a half-round groove 20mm across and a rim 25mm wide. Two pressed steel plates hold it, and each plate turns out into a foot flange at its base, so you weld the flanges to your gate's bottom rail and do not need an axle bolt. The flanges have no bolt holes, so this is a weld-on fitting. On the data sheet the running edge stands 17mm below the flanges, which is what sets the gap under your gate. No load rating is published for this wheel. The price shown is for one wheel, with a minimum order of 6.

Why this wheel works

The small weld-on size. At 78mm measured with plates 50mm high and a base of 46mm across, this is the compact option for a gate frame with a shallow channel. The wheel stands 17mm below the flanges.

Weld once and leave it. With the plates welded to the rail, there is no axle bolt to come loose, and the wheel holds its position in the frame.

The groove holds the line. The half-round groove keeps the wheel on the track, so the gate runs straight and does not wander off the round bar.

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

Plated against rust. The wheel and plates are yellow zinc plated, not hot-dip galvanised, so paint the welds after fitting.

Where it is used

Light sliding gates on 20mm round bar track where the wheel is welded into the bottom rail, in fabrication shops and for replacement on gates with a shallow channel.

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.

This is the smallest wheel with plates. The 100mm wheel with plates moves to a 98mm wheel, 65mm high plates and a 52mm base, for a deeper rail. If you would rather bolt the wheel through a bracket, the 80mm double bearing wheel with an M10 axle has the same diameter and groove. Make sure the 46mm flange width and 50mm plate height suit your rail before you weld.

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. Weld the flanges to the underside of your bottom rail, with the plates and the top of the wheel up inside an open-bottomed channel or a slot cut in the rail. On the data sheet the running edge stands 17mm below the flanges, so measure your gap from there. Tack first, check the gate runs true along the full length, then weld in short runs to keep heat away from the bearings.

Keep grit and leaves off the track, because that is what wears a wheel. Paint the welds, and check the wheels run freely at each service.
