Rebuild parts

If the rig is sound and only the wheel is worn, replace the wheel. We stock 4 x 1-1/2 in epoxy oven-rack wheels with 5/16, 3/8 and 1/2 in bores, and swivel yokes for a 4 in wheel on a 3-1/8 x 4-1/8 in plate with a 5/16 in bore, listed to 550°F [S1]. A 3 x 1-3/4 in pan dolly caster is also listed here.

What to check before you order

  1. Oven temperature. Compare the hottest setting your rack sees with the listed range. Epoxy and the 5 in glass-filled nylon list 550°F for short exposure; the 4 in glass-filled nylon lists 450°F.
  2. Load per caster. Most casters here are rated 300 lb, so a four-caster rack carries about 1,200 lb. The glass-filled nylon casters are rated 350 lb.
  3. Mount. Measure the plate and bolt holes. Most casters here use the 3-1/8 x 4-1/8 in plate; the 5 in nylon caster uses a 3/4 x 2 in stem.
  4. Wheel bore. For a wheel-only replacement, match the bore to your axle: 5/16, 3/8 or 1/2 in.
