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.

PRODUCT CODE: HQ-UB-RCS
This product listing is the most common U-Boat Cart Replacement Caster Set. U-Boats are commonly seen on Platform Trucks, Stock Carts, Grocery Store Carts, etc. This listing is for two pieces of our 8" x 2" Swivel Casters with our Polyurethane on Polyolefin Wheels and four pieces of our 4" x 1-1/4" Swivel Caster with our Polyurethane on Polyolefin Wheels for a total of six replacement Casters. The Caster configuration on this listing is a direct replacement for U-Boat carts with two 8" swivel Casters for the middle of the carts and four 4" swivel casters for the corners. Industry-standard replacement wheels and a direct fitment for almost all major brand u-boat carts.
This caster setup is great for the zero-turn carts which will allow the user to turn the cart 360 degrees without having to move it forward or backward which is why the large 8" casters are also swivels which is a newer setup on certain carts but very beneficial for specific applications such as limited maneuverability and limited space.
