Double Bearing Sliding Gate Wheel 120mm, 20mm Round Track, Bracket Mount

A 120mm double bearing wheel in a wide bracket, for sliding gates on 20mm round track. Listed at 120mm and given as 118mm on the data sheet, this wheel sits between the 100mm and 140mm sizes and is fitted in a pressed steel bracket 158mm long and 42mm wide. Its 30mm wide wheel and two bearings suit a gate that sees regular use, and the bracket bolts to the rail through two 10mm wide slots at 128mm centres. Check your rail will take a 42mm bracket before you order. The price shown is for one wheel with its bracket, with a minimum order of 5.

Important: This wheel runs on 20mm diameter round bar track only. It will not run on V section track or in a cantilever track. Data sheet sizes are a guide; components can vary slightly.

Why this wheel works

A half round groove on a round bar. The groove cups the top of a 20mm round bar and spreads the load along the contact, which keeps the gate centred as it travels and gives a quieter roll than a flat wheel.

Two bearings in the hub. The axle runs on two bearings, which share the load and help the wheel run true when the gate is pushed from one side. Choose it for gates that are used all day or driven by a motor.

The step between 100mm and 140mm. At 127mm overall it costs you less height than the 140mm wheel at 150mm, but it gives more roll and a wider tyre than the 100mm size. The 30mm wheel width gives the groove more steel around the round bar than the 25mm width of the smaller wheels.

Where it is used

Medium to large steel sliding gates on 20mm round bar at commercial sites, yards and depots, on a rail with at least 42mm of flat underside. It is a sensible upgrade where a 100mm wheel seems marginal on a long gate. It is not for cantilever gates or V section track.

Specifications

Choosing the right wheel

Stepping down to the 100mm double bearing wheel gives you a smaller 130mm bracket, a 35mm rail width and a published 600kg advised figure. Stepping up to the 140mm double bearing wheel adds height and a larger wheel. This 120mm wheel has no published load figure, so if a figure is essential for your job, take the 100mm size or call us. If you need a wheel hidden in the rail, we also list a 120mm box section housing wheel.

Fitting and care

Mark the wheel positions on the bottom rail so the two wheels sit close to the ends of the gate and in line with the track. The bracket needs a flat underside 42mm wide. Bolt through the two holes at 128mm centres, or weld the bracket after grinding the plating off the weld area and working with fume extraction. Fixings are not listed as included, so allow your own. Set the gate so that the wheels sit fully on the track along its whole travel.

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.
