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.

3 Inch Institutional Phenolic Wheel Casters

These 3 in phenolic wheel casters fit light carts, racks, and stands. Casters in this collection are rated 350 lb per caster. Wheels are 3 x 1-1/4 in swivel, rigid, and brake models. Phenolic handles dry heat, oil, and grease, but it is not made for water or washdown. Phenolic rolls easily on smooth floors and handles heat, oil, and grease. It is hard, so it is loud on rough floors. 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. 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. Phenolic aisle: phenolic casters. Light duty hub: light duty casters.
