Nylon Bulb Roller 30mm, 10mm Threaded Stud, for Sliding Gate Guides

A small bulb shaped nylon roller on a 10mm threaded stud. The tapered black body and the rounded band give it a low-friction contact point against a gate frame, and the stud with its two nuts and washers fits it to a bracket or a drilled plate. It is sold as a 30mm roller and drawn at 31mm across the widest point, with a head 27mm high and 60mm overall including the stud. A load rating is not published for this line, and it is a guide part, not a wheel for carrying a gate. The price shown is for one roller, with a minimum order of 15.

Why a bulb roller works

The rounded band rolls rather than rubs. A gate frame that touches a fixed block wears both surfaces, whereas a small roller turns with the movement and is kinder to the paint.

The stud is adjustable. Two nuts on the 10mm stud let you set the head at exactly the right distance from the gate, then lock it.

Cheap to replace. These are wearing parts. It is much better to change a small roller than to repaint a gate frame scored by a worn guide.

Where it is used

Guide brackets and post plates on sliding gates, and gate frames that need steadying as they travel, usually fitted in pairs on opposite sides of the gate. The 30mm roller and 10mm stud suit compact guide plates and lighter sliding frames.

Specifications

Choosing the right roller

This is the smaller of the two bulb rollers, with a 10mm stud and a compact 27mm head, so it fits where the guide plate or the frame leaves little room. Check the hole in your bracket before ordering, as the stud size has to suit it. If you need a longer contact on a tall rail, a long roller does that job, and a ready-made bracket with rollers fixed in place saves you drilling.

Fitting and care

Fit the stud through your bracket, with one nut each side of the bracket and a washer against the roller's shoulder, and set the head so the gate runs close beside it without forcing against it. Lock the two nuts together. A roller should turn when the gate touches it, so run the gate by hand and check it does not bind before tightening fully.

Check the rollers at each service, especially on a gate that opens many times a day, and change any roller that has flats or has stopped turning.
