OEM Specific Casters · 3" to 10"

These OEM fit casters and wheels fit light carts, racks, and stands. Casters in this collection range from 300 to 550 lb per caster. Wheels are 3 to 10 in polyolefin, hard rubber, polyurethane, and flat free in swivel and brake models. Sets of 4 show the combined set rating on the title, so divide by 4 for the per caster load. Six packs divide the set rating by 6. Wheel options include polyurethane, nylon, phenolic, and forged steel, so match the tread to the floor and the load. Softer polyurethane or soft rubber or TPR tread is the better pick when the floor has chips or grit. Threaded stem, grip-ring, and expanding rubber stems for round and square tubing all appear on light-duty builds. Match plate size, bolt pattern, and overall height before you order. Read the listing for the exact wheel size, overall height, and mount shown. Heavy duty hub: heavy duty casters. Light duty hub: light duty casters.

Choosing OEM replacement casters

  1. Load: divide the loaded weight by three for a four-caster cart [S2]. A 300 lb caster from this page then suits about 900 lb, and the strongest at 300 lb about 900 lb.
  2. Mount: most OEM replacement casters use a 2-1/2 x 3-5/8 in top plate; check the bolt spacing on your frame against the plate size.
  3. Floor: on OEM replacement casters, polyurethane and rubber are kinder to tile and finished floors; polyolefin rolls easier under heavy loads on smooth concrete.
  4. Rig: swivel OEM replacement casters are listed.
