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.

Rubber Casters

This collection holds Rubber Casters, built for shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection range from 400 to 600 lb per caster. Wheels in this category range from 4 up to 8 inches in diameter with a 2 in tread width. The collection includes swivel and rigid models. Rubber wheels are quiet, cushion the load, and protect floors. Nylon rolls easily, resists water and many chemicals, and is hard, so it is loud on rough floors. Soft rubber or TPR is the better pick when the floor has chips or grit. Match plate size, bolt pattern, and overall height before you order. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Rubber aisle: rubber casters. Wheel hub: replacement wheels.
