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.
























Track wheels that ride on angle iron or flat rail: V-groove wheels in cast iron, ductile iron and NyloForce polymer, and Hamilton single and double flanged wheels.








| Type | Sizes (typical) | Per wheel | Notes |
|---|---|---|---|
| Cast iron V-groove | 3 to 8 in | About 350 to 1,200 lb | Budget rail work |
| Ductile iron V-groove | 4 to 10 in | About 1,500 to 7,000 lb | Higher shock and load |
| NyloForce V-groove | 4 to 8 x 2 in | About 2,200 lb where listed | Lighter, quieter polymer |
| Hamilton flanged (WFT) | About 8 to 9-1/4 in | About 2,000 to 4,750 lb | Single/double flange; Pronto vs long lead |

V-groove rides inverted angle iron. Flanged wheels ride a flat rail with a side flange to stay on track. Match the rail you already have.
Yes. Complete sliding-gate and V-track casters live on the sliding gate wheels hub. Swing-gate spring wheels live on gate casters.
