All measurements indicate the wheel diameter by the tread width.

The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

Grip Ring Casters

This collection holds Grip Ring Casters with TPR wheels, built for light carts, racks, and stands. Casters in this collection range from 110 to 165 lb per caster. Wheels in this category are 3 inches in diameter with a 0.94 in tread width. The collection includes swivel and brake models. Dual wheel casters split the load over two wheels and swivel with less effort under heavy loads. Thermoplastic rubber (TPR) is quiet, will not mark floors, and rolls over chips and grit. 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. Match plate size, bolt pattern, and overall height before you order. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. TPR aisle: tpr casters. Wheel hub: replacement wheels.

Choosing MedCaster grip ring casters

  1. Load: divide the loaded weight by three for a four-caster cart [S2]; at 165 lb each, MedCaster grip ring casters suit a loaded cart of about 495 lb.
  2. Stem: the most common stem on MedCaster grip ring casters is 7/16 x 7/8 in; 3 x 15/16 in also appear; measure thread size and length, or the tube inside diameter, on the old caster.
  3. Floor: on MedCaster grip ring casters, rubber and polyurethane protect finished floors and run quietly; check the rating if the cart also crosses rough concrete.
  4. Rig: swivel MedCaster grip ring casters are listed, with side lock brake options.
