Sliding Gate Guide Roller 40mm x 250mm, Extra Long Nylon on Threaded Spindle

A long roller for guiding a sliding gate past its post. A guide roller stops a sliding gate from leaning as it travels, and a short roller only touches the gate over a small height. This one is 250mm long, so it covers a much deeper part of the gate frame and keeps contact even when the gate rides slightly high or low. The roller is black nylon, 40mm across, on a steel spindle with a 17mm threaded end, washers and two nuts. The overall length is 296mm. A load rating is not published for this line. The price shown is for one roller with its spindle and fixings. The minimum order is 6.

Why a long roller works

It keeps contact over a greater height. A gate that lifts or drops slightly along its track, or that has a tall upright frame, stays against the roller where a short one would run off the edge of the rail.

Nylon on steel. The nylon surface rolls quietly against a painted or galvanised frame and is much kinder to the coating than a bare steel roller would be.

Simple, adjustable fixing. The threaded end takes a bracket or a drilled plate, with the two nuts locking it at the height you need.

Where it is used

Guide posts on sliding gates at commercial yards and logistics sites, usually fitted as a pair with one either side of the gate. It suits gates with a deep top rail or a tall frame, and gates that move slightly up and down along their track. It guides the gate only: it does not carry the gate's weight.

Specifications

Choosing the right roller

The length is what sets this roller apart. Our standard guide rollers are short and suit a rail that sits at a known height, whereas this one is for gates where contact over a greater height matters. A roller with rubber rings runs more softly, and a guide bracket with several rollers is a complete top guide rather than a single part.

Fitting and care

Fix the spindle into a drilled bracket or plate on the guide post, set the roller beside the gate with a small running clearance, and lock it with the two nuts. Fit a roller on each side of the gate so that it cannot lean either way. Move the gate by hand over its whole travel to check the rollers do not bind, then tighten the nuts fully.

Wipe the roller clean at each service and check for flats or splits. Replace it if the nylon has worn or if the spindle has bent.
