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.






Silent casters with soft, non-marking thermo rubber wheels on polished 304 stainless kingpinless rigs. 6 and 8 x 2 in, swivel or rigid, with a top lock brake option, rated 600 to 675 lb each on a 4 x 4-1/2 in plate.
Noise from a caster comes from a hard wheel hitting seams and debris, and from a loose swivel chattering. These casters attack both. The thermo rubber tread is soft, so it flexes over joints instead of banging across them, and the kingpinless swivel has no center bolt to wear loose [S1].
| Size | Options | Rating | Height |
|---|---|---|---|
| 6 x 2 in | Swivel, rigid | 600 lb | 7-1/2 in |
| 8 x 2 in | Swivel, rigid, swivel with top lock brake | 675 lb | 9-1/2 in |
From product fields [S1]. All use a 4 x 4-1/2 in plate.
Soft rubber takes more effort to start rolling than a hard wheel under the same load, and it can take a flat spot if a heavy load sits for weeks. If noise is not a concern and loads are high, polyurethane is the better tread.

A soft tread that flexes over seams and a swivel that does not rattle. These use thermo rubber wheels on kingpinless stainless rigs.
The 6 in models are rated 600 lb each and the 8 in models 675 lb each.
No. The thermo rubber tread is non-marking.
Yes. The frames are polished 304 stainless steel and the axle has a grease fitting for re-lubrication after washing.
