Sliding Gate Double Wheel 100mm, 20mm Round Track, Top Plate Carriage, 700kg Limit

Two 100mm wheels in one carriage, ready to fix under the bottom rail of a sliding gate. A single wheel puts the whole of its share of the gate on one small contact point. This carriage shares that load between two grooved wheels running one behind the other, inside a pressed steel housing with a flat top plate. The plate is 230mm long with fixing holes at 205mm centres, so it fixes straight to the underside of a box section rail. It is made for 20mm round track. The published maximum weight limit is 700kg, and the price shown is for one carriage.

Why two wheels in one carriage work

The load is shared along the track. With two wheels in line, the gate's weight is spread over two points on the rail instead of one, which is kinder to both the wheel and the track.

The housing is the mounting. The pressed cheeks hold both axles at a fixed spacing, so you are not setting up two separate wheels and trying to keep them in line by eye.

A flat plate is quick to fix. The 230mm plate sits flat against the rail and the holes are clear of the wheels, so the fixings can be reached with a normal socket.

Where it is used

Sliding vehicle and pedestrian gates at warehouses, yards, depots and trade premises, usually with one carriage near each end of the gate. The larger 100mm wheels and the 20mm round groove suit gates already running on, or being built for, 20mm round track. Gate length is not published for this line, so work from the weight limit and the track you have.

Specifications

Choosing the right wheel

Start with the gate's weight and the track. This is the larger of the two pressed carriages, with 100mm wheels and a 205mm hole spacing, and the groove is made for 20mm round track. Pressed cheeks keep the carriage narrow. If your gate needs a stronger unit, the heavy duty version uses a thick plate and two separately mounted wheels. A single wheel makes sense on lighter gates or where the rail is too short for a double carriage.

Fitting and care

Set the track first and check it is straight and level along the whole run, because any wheel will wear quickly on a track that rises and falls. Offer the carriage up beneath the bottom rail and mark the two holes at 205mm centres. Fixings are not included unless shown, so allow for bolts that suit your rail. Fit one carriage towards each end of the gate so the weight is shared, then roll the gate by hand along the whole track before connecting any motor.

Keep the track clear of grit, leaves and stones, since debris in the groove is what causes most rough running. Check the fixings at each service. Bright plated finishes will dull on an exposed site, and welding the plate burns the coating away, so touch up any bare steel with zinc-rich paint.
