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.

4" x 2" Polyurethane Casters · 700 lb · 4" x 4-1/2" Plate

These 4 in poly on polyolefin casters fit shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection are rated 700 lb per caster. Wheels are 4 x 2 in swivel, rigid, and brake models. Polyurethane on polyolefin wheels are quiet and floor safe at a low cost. The poly tread resists water and many cleaning chemicals. Softer polyurethane or soft rubber or TPR tread is the better pick when the floor has chips or grit. Match the 4 x 4-1/2 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. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Polyurethane wheel aisle: polyurethane wheels. Plate aisle: plate casters.
