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.
