Hinge Installation and Selection

There are a few type of hinges. The fall into two brackets, adjustable and not adjustable, lubricated and not lubricated.

Close up of 1" flange Bearing. The bracket shown here has slots for the bolts and is adjustable.

1" sealed flange bearing. This is becoming one of the most common means of hinging a gate. These can hold up to 1000 Lb. gates and can be up sized as well. If bolt holes are slotted these become adjustable. I feel this is the best all around hinge.

  Square body hinge. Has stainless steel pin and grease fitting. The hinge has one bearing as can be seen below. These are strong hinges but are hard to replace when they fail. The pin has a lot of lateral force and eventually the pin hole elongates. It is also hard to adjust these hinges if there is any sag in the gate or for critical alignment when installing bi-parting gates.
This is a flange bearing installed on a skeleton. This is a good method for hanging gates on columns.

This is a pin hinge using a thrust bearing. This is a cut above a simple pin hinge. Eventually the hole will elongate on the female half.
Rudimentary pin hinge. This is a simple hinge used on light ranch gates. This is not a good hinge for use on heavy driveway gates.
This is a hybrid hinge. It uses the adjustable threaded rod and connects to a lubricated block hinge. It seems like a good idea for medium weight gates.

Rudimentary pin hinge. This is a simple hinge used on light garden gates. This is not a good hinge for use on heavy garden gates.
Teflon block hinge. These are used on aluminum gates and are not meant to take heavy loads. This is an easily adjustable hinge and would work well on bi-parting gates. Not available for retail sale.
