Back to Casters

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.

14 mm bore keyed wheels by tread

Tread Core Wheel sizes Rated per wheel Listed temperature Where it fits
Polyurethane Steel 4, 5, 6 and 8 in 450 to 1,000 lb quiet, floor-friendly and long wearing

Ratings are for single wheels of 14 mm bore keyed wheels, from product fields [S1].

Wheel sizes

Wheel Treads Rated
4 x 1-1/2 in polyurethane 450 lb
4 x 2 in polyurethane 600 lb
5 x 1-1/2 in polyurethane 600 lb
5 x 2 in polyurethane 800 lb

8 x 2 in polyurethane 1,000 lb

Choosing 14 mm bore keyed wheels

  1. Load: divide the loaded weight by three for a four-wheel cart [S2]. A 800 lb wheel from this page then suits about 2,400 lb, and the strongest at 1,000 lb about 3,000 lb.
  2. Floor: on 14 mm bore keyed wheels, polyurethane protects finished floors and runs quietly; check the rating if the cart also crosses rough concrete.
