This product listing is the most common U-Boat Cart Replacement Wheel & Caster Set. U-Boats are commonly seen on Home Depot Carts, Lowes Carts, At Home Carts, Platform Trucks, Stock Carts, Grocery Store Carts, etc. This listing is for two pieces of our 8" x 2" Polyurethane on Polyolefin Wheels and four pieces of our 4" x 1-1/4" Swivel Casters with our Polyurethane on Polyolefin Wheels for a total of 4 replacement 4-inch casters and 2 replacement 8-inch wheels. We also include the replacement axles and lock nuts for the two pieces of our 8-inch wheels as seen in the photo. The wheel configuration on this listing is a direct replacement for U-Boat carts with two 8" wheels 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 U-Boat Platform Truck 1,800 lb Replacement Caster & Wheel Kit is rated to 1800 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.
This caster runs a Polyurethane wheel with a 2" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.
This is a Swivel caster. Swivel casters rotate 360 degrees for full maneuverability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -20°F to 180°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).
The Polyurethane wheel performs best on smooth to semi-smooth floors including sealed concrete, tile, and epoxy. For non-marking or clean-environment needs, ask us about matching tread options.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
