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.

6 x 2 in rubber casters by tread

Tread Core Wheel sizes Rated per caster Listed temperature Where it fits
Rubber Polyolefin 6 in 500 to 600 lb -40°F to 180°F cushioned and quiet on finished floors

Ratings are for single casters of 6 x 2 in rubber casters, from product fields [S1].

Choosing 6 x 2 in rubber casters

  1. Load: divide the loaded weight by three for a four-caster cart [S2]; at 600 lb each, 6 x 2 in rubber casters suit a loaded cart of about 1,800 lb.
  2. Mount: most 6 x 2 in rubber casters use a 4 x 4-1/2 in top plate; match the bolt holes on your frame to the plate before ordering.
  3. Floor: on 6 x 2 in rubber casters, rubber protects finished floors and runs quietly; check the rating if the cart also crosses rough concrete.
  4. Rig: swivel and rigid 6 x 2 in rubber casters are listed, with side lock brake options.
