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.







Our 4 inch (4" x 2") Polyolefin Wheels are made of Industrial Plastic and very inexpensive. CasterHQ's Polyolefin Wheels are lightweight, strong, and very affordable. These wheels are solid injection molded and provide high impact resistance and can handle shock loads and abrasion. Polyolefin wheels are 100% washable and resist water, oils, solvents, greases, chemicals, cooking fats, and acids. This wheel is a great wheel used on medium-duty applications such as toolboxes, carts, Bakery Equipment, Food Service Equipment, Furniture, Hotels, laboratories, Manufacturing, Medical / Hospital, Warehouses, and Wet Corrosive Environments. The Swivel Casters raceway comes with Double Ball Bearings, a zinc plate finish for additional rust resistance, and 1/4" cold-forged steel top plate and yoke legs. These Swivel and Rigid rigs can hold up to 1,250 lbs but you always want to base the weight capacity off the product with the lower-rated capacity depending on the wheel or rig. We offer brake options and many upgrades on the right-hand side of each product page. CasterHQ only provides high-quality industrial casters that are ISO:8001 Certified, NSF Listed and Approved, RoHS Compliant.
