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.
Keyed drive wheels — precision wheels with keyed bores for AGV, AMR, motorized vehicles, and powered industrial equipment. The key locks the wheel to the motor shaft so torque is transmitted without slipping. Polyurethane, hard rubber, or steel tread options. Stocked at our Mansfield, TX facility.
























Drive wheels on AGVs and motorized equipment use a keyed bore (a notch cut into the wheel's hub) that locks onto a corresponding key on the motor drive shaft. Prevents the wheel from slipping under torque.
Match wheel bore to motor shaft diameter exactly. 1 inch, 1-1/4 inch, 1-1/2 inch most common.
Keyway dimensions must match motor shaft's key. Common: 1/4 x 1/8, 5/16 x 5/32.
Polyurethane for indoor smooth floors (most common AGV use). Rubber for noise control. Steel for heavy/abrasive environments.
For non-standard bore or keyway sizes, contact us — keyed drive wheels are commonly made to spec.
