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.
Capacity shown is per caster (per wheel for wheels).
























Keyed drive wheels for AGVs, tuggers and powered carts: polyurethane treads on steel hubs with a keyway, 4 to 10 in, bores 1/2 to 1-1/2 in, rated 450 to 2,250 lb each.








A drive wheel has to put torque into the floor as well as carry weight. Polyurethane gives grip and holds its shape under load; the steel hub carries the keyway without cracking. Rubber grips better on wet floors but deflects more and wears faster under torque.
| Size | Listed ratings |
|---|---|
| 4 x 1-1/2, 4 x 2 in | 450 to 600 lb |
| 5 x 1-1/2, 5 x 2 in | 600 to 900 lb |
| 6 x 1-1/2, 6 x 2, 6 x 3 in | 600 to 1,500 lb |
| 8 x 2, 8 x 3 in | 1,000 to 1,850 lb |
| 10 x 3 in | 2,200 to 2,250 lb |
From product titles and fields [S1].
The listings note that keyways can be machined in most wheel sizes, as long as the hub is large enough [S1].

A wheel with a keyway in its hub that locks to a keyed shaft, so it turns with the motor without slipping.
Listed bores include 1/2, 5/8, 3/4, 1, 1-1/4 and 1-1/2 in.
From 450 lb (4 in) to 2,250 lb (10 x 3 in) each.
