Double Bearing 180 Degree Gate Hinge, 125mm, Black, Bolt-On, Gates to 150kg

A bolt-on gate hinge that swings a full 180 degrees on two stainless steel bearings. The housing is black powder coated aluminium, and it fixes from the front through 15mm holes at 40mm centres in the post and the gate, with no welding. The fixing bolts expand inside the hollow section and cover plates clip over them, so the fixings cannot be reached from outside once the gate is hung. It is reversible, so the same hinge goes on a left or right hand gate. Rated for gates up to 150kg and 1.5m wide. Hinges of this type are normally fitted as a pair, and the price shown is for one hinge.

Why this hinge works

Two bearings do the work. A pin turning in plain steel wears a groove and starts to bind. Here the gate turns on two stainless steel bearings inside the barrel, so a tall or heavy leaf keeps moving easily and quietly.

You do not need a welder or a paint repair. Drill the holes, push the bolts through and tighten them from the front. That matters on a powder coated or galvanised gate, where welding would burn off the finish you have paid for.

It stays fixed. The bolts are not exposed once the covers are on, which suits schools, parks, communal gardens and anywhere else that a gate might be interfered with.

The hinge opens a full 180 degrees, so the leaf can fold back along the fence and stay out of the way.

Where it is used

Aluminium and steel pedestrian gates on commercial sites, schools and playing fields, communal bin stores and courtyards, and residential estates with a matching gate line. It can also be paired with a hydraulic closer hinge where the gate has to close itself.

Specifications

Choosing the right hinge

This is the current version of our 180 degree double bearing hinge, and its published sizes differ from the earlier one we still list. It measures 125mm across the leaves, 96mm high and 64mm deep. The earlier hinge is listed as 115mm high, 109mm over the fixings and 60.5mm deep. Both use 15mm holes at 40mm centres, but do not assume the bodies match, so if you are replacing a single hinge on an existing gate measure the old one first, or replace both as a pair. Use the table below to compare the other bolt-on options, and check your gate is inside the 150kg and 1.5m limit before ordering.

Fitting and care

Fit one hinge near the top of the gate and one near the bottom. Mark the positions on the post and the gate so they line up, and drill 15mm holes at 40mm centres through the front wall of each section. Push in the expanding bolts, tighten them from the front and clip on the covers. Hang the gate on packers, check the swing and the gap at the post, then finish tightening. Hollow sections need enough wall thickness to take the fixings, so ask us if your frame is unusually thin.

Wipe the housing clean when you wash the gate. Check that the bolts are still tight at routine inspections.
