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.

Durastar PTU/DTU 4" DURATOUGH Polyurethane Wheels

This collection holds Durastar Ptu Dtu 4 Inch Duratough Polyurethane Wheels with polyolefin and polyurethane treads, made to replace worn wheels on carts, dollies, racks, and equipment. Wheels in this collection range from 325 to 700 lb per wheel. Wheels in this category are 4 inches in diameter with 1-1/4 to 2 in tread widths. Polyolefin is light, low cost, and resists water and many chemicals. It is hard, so it is loud on rough floors. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Match the bore, hub length, diameter, and tread width before you order. Order the axle and spacers if the old ones are worn. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Measure the old wheel or caster before you buy. Polyolefin aisle: polyolefin casters. Caster hub: heavy duty casters.
