3-1/8 x 4-1/8 Plate Casters | 3-5 in Wheels

These plate casters use the popular 3-1/8 x 4-1/8 in top plate found on carts, dollies, and equipment stands. Casters in this collection range from 180 to 800 lb per caster. Most light duty models run 180 to 350 lb, and P&H 20 and 26 series models reach 500 to 800 lb. Wheels in this category range from 3 up to 5 in in TPR, poly on poly, phenolic, polyolefin, and semi steel. Sets of 4 show the combined set rating on the title, so divide by 4 for the per caster 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 the 3-1/8 x 4-1/8 in plate, bolt pattern, and overall height before you order.

Choosing 3-1/8 x 4-1/8 in plate casters

Load: plan on three casters carrying a four-caster cart [S2]; at 325 lb each, a common rating here, that is about 975 lb, and the 400 lb top rating covers about 1,200 lb.
Mount: most 3-1/8 x 4-1/8 in plate casters use a 3-1/8 x 4-1/8 in top plate; 2-3/8 x 3-5/8 in plates are listed too; measure bolt hole centers on the old plate and compare.
Floor: on 3-1/8 x 4-1/8 in plate casters, polyurethane, TPR and rubber are kinder to tile and finished floors; phenolic, nylon and polyolefin roll easier under heavy loads on smooth concrete.

Heat: among 3-1/8 x 4-1/8 in plate casters, the highest listed range is up to 550°F on nylon; check the temperature field on each listing before oven or hot-room use.
