All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.
Wheel = wheel diameter · capacity is per wheel.

The spring lets the wheel follow small dips and bumps while it holds up the free end of the gate, so the hinges and post carry less of the weight. Size the caster by the weight at the wheel end, not the whole gate.

|---|---|---|

| Ductile iron V-groove wheels | 4 to 8 in | 1,500 to 6,000 lb |
| CasterHQ cast iron V-groove rigid casters | 4 to 8 x 2 in, 4-1/2 x 6-1/4 in plate | 700 to 1,400 lb |

A V-groove wheel needs a matching inverted angle track. Match the groove angle and width to the track before ordering. Wheels without a rig bolt into your own bracket. For more track wheels see V-track sliding gate wheels.
It bolts under the free end of the gate. The wheel holds up that end and the spring lets it follow uneven ground, so the hinges and post carry less weight.
Spring-loaded gate casters here are rated 110 to 1,000 lb each. V-groove wheels for sliding gates run from 350 lb up to Hamilton forged steel casters rated in the thousands of pounds.
A wheel with a V-shaped groove that rides on an inverted angle-iron track, used on sliding gates.
