Light-Medium Duty Plate Casters: 2-3/8 x 3-5/8 Top Plate

These light duty plate casters all use the popular 2-3/8 x 3-5/8 in top plate found on carts, racks, and equipment stands. Casters in this collection range from 150 to 450 lb per caster for most models. Wheels in this category range from 3 up to 5 in in polyurethane (poly or urethane), TPR, phenolic, semi steel, and polyolefin. Softer poly or soft rubber or TPR is the better pick when the floor has chips or grit. Common uses include food service, bakeries, hospitals, schools, laboratories, and material handling carts. Threaded stem, grip-ring, and expanding rubber stems for round and square tubing all appear on light-duty builds. Match the 2-3/8 x 3-5/8 in plate, bolt pattern, and overall height before you order. Choose swivel casters when the cart must turn in place, rigid casters for straight travel, and add a brake when the cart needs to stay put. Plate aisle: plate casters.

Choosing 2-3/8 x 3-5/8 in plate casters

Load: divide the loaded weight by three for a four-caster cart [S2]. A 340 lb caster from this page then suits about 1,020 lb, and the strongest at 770 lb about 2,310 lb.
Mount: most 2-3/8 x 3-5/8 in plate casters use a 2-3/8 x 3-5/8 in top plate; 2-1/2 x 3-5/8 in and 3-3/8 x 3-15/16 in plates are listed too; check the bolt spacing on your frame against the plate size.
Floor: on 2-3/8 x 3-5/8 in plate casters, polyurethane, TPR and rubber are kinder to tile and finished floors; phenolic, semi-steel, polyolefin and steel roll easier under heavy loads on smooth concrete.
Rig: swivel and rigid 2-3/8 x 3-5/8 in plate casters are listed, with side lock brake, top lock brake and total lock brake options.
Heat: among 2-3/8 x 3-5/8 in plate casters, the highest listed range is -45°F to 600°F on semi-steel; check the temperature field on each listing before oven or hot-room use.
