Description
A heavy rotating bottom hinge on an L-shaped bracket that you can weld on or bolt on, for swing gates that turn on a bearing. The zinc-plated bracket fixes to the post through three 11mm holes or by welding, and its arm carries a 60mm round two-part housing with a taper roller bearing inside and a grease nipple on the cap. The lower part bolts through a slot in the arm so it can be moved into line, and the upper cap welds to the underside of the gate. A gate uses one bottom hinge and one top hinge, and the matching 60mm top rotating gate hinge, weld or bolt on is the partner for this part. The price shown is for one bottom hinge, with a minimum order of 3.
What you get
| Bracket | One L-shaped bracket, 10mm thick, with a 30 x 15mm slot and three 11mm fixing holes |
|---|---|
| Housing | Two-part 60mm housing: 15mm base and 20mm cap with grease nipple |
| Bearing | Taper roller bearing, fitted inside the housing |
| Fixing kit | Bolt, serrated washer and washer under the arm, plus a grub screw in the end of the arm |
| Not included | Post fixings, the top hinge, and weld |
Why choose this hinge
Weld it or bolt it. Weld the bracket to a steel post, or bolt it through the three 11mm holes with M10 fixings to steel or masonry. Bolting on means no welding at the post, which helps on a finished or galvanised post.
Carries the weight on a bearing. A taper roller bearing takes the weight of the gate and the side load, so a heavy leaf turns with a light push instead of dragging on a hinge pin.
Line it up before you fix it. The 30mm slot in the arm lets the housing move along the arm, so you can bring the pivot directly under the top hinge before tightening the bolt.
Greaseable. The nipple on the cap lets you grease the bearing in place, without taking the gate down.
How much will it carry?
| Gate width | Maximum gate weight |
|---|---|
| 1m | 700kg |
| 2m | 350kg |
| 3m | 175kg |
Wider gates put more leverage on the hinge, so the safe weight falls as the gate gets wider. Always check the weight of the finished gate, including any cladding or infill, and use the figure for your gate width.
Where it is used
Heavy steel driveway and estate gates, solid-panel and clad gates, commercial and yard gates, and any gate where you want a bearing at the bottom without setting a base plate into the ground. Because the bracket fixes to the post, the pivot sits clear of the paving and standing water.

Fitting
Fix the bracket to the post at the bottom hanging corner, with the arm level and the upright flat against the post. Bolt through the three holes or weld the upright to the post. Stand the gate on the cap, with the housing loose on the arm, and prop the gate upright. Fit the top hinge above, then slide the housing along the slot until the pivot and the top hinge are in one true vertical line. Tighten the bolt under the arm and nip up the grub screw in the end of the arm. Check the swing, then weld the cap to the underside of the gate stile in short runs so the bearing is not overheated. Paint the welds with zinc-rich primer, and grease through the nipple once everything has cooled.
Care
Grease through the nipple every six months, check that the bolt under the arm is tight each spring, and keep grit and leaves cleared from around the housing.
Frequently asked questions
Do I need a top hinge as well?
Yes. A gate uses one bottom hinge and one top hinge: this part carries the weight and the top hinge holds the gate upright. The matching 60mm top rotating gate hinge, weld or bolt on uses the same bracket and has the same rating.
Is the price for one?
Yes, the price is for one bottom hinge, with a minimum order of 3. Each gate leaf takes one of these and one top hinge.
What fixings do I need to bolt it on?
Three M10 bolts or resin anchors suited to your post. They are not included.
Is it left or right handed?
Neither. It works under either hand of gate.
Do I have to weld anything?
The cap welds to the underside of the gate, so yes, some welding is needed on the gate. The bracket can be bolted on if you prefer not to weld at the post.
