Double Bearing Gate Wheel with Weld-On Plates 100mm, 20mm Round Groove

A 100mm wheel with weld-on side plates, for a sliding gate running on a 20mm round bar ground track. The wheel is 98mm 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 18mm 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 mid size of weld-on wheel. A 98mm wheel with 65mm high plates and a 52mm base, for a rail with enough depth to take it. The wheel stands 18mm below the flanges on the data sheet.

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

Sliding gates on 20mm round bar track where you are welding the wheel into the bottom rail, on new gates and on replacements of the same size. A good fit where the rail is deep enough to hide most of the wheel.

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.

Down a size, the 80mm wheel with plates has a 46mm base and 50mm high plates. Up a size, the 120mm wheel with plates has a 54mm base and 76mm high plates and a wider rim. The V groove version of this size has the same plates and wheel diameter but needs a V section track. If you would rather bolt a wheel through a bracket, the 100mm double bearing wheel with an M14 axle is the same size and groove.

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 18mm 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.
