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.

8 inch spring loaded casters by tread

Tread Core Wheel sizes Rated per caster Listed temperature Where it fits
Polyurethane 8 in 2,000 lb Up to 180°F quiet, floor-friendly and long wearing

Ratings are for single casters of 8 inch spring loaded casters, from product fields [S1].

Choosing 8 inch spring loaded casters

  1. Load: divide the loaded weight by three for a four-caster cart [S2]; at 2,000 lb each, 8 inch spring loaded casters suit a loaded cart of about 6,000 lb.
  2. Mount: most 8 inch spring loaded casters use a 4 x 4-1/2 in top plate; check the bolt spacing on your frame against the plate size.
  3. Floor: on 8 inch spring loaded casters, polyurethane protects finished floors and runs quietly; check the rating if the cart also crosses rough concrete.
  4. Rig: swivel and rigid 8 inch spring loaded casters are listed.
