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.

4" x 2" Polyurethane Casters

Custom made to order. All sales final.

Each Hamilton product is custom manufactured for your order (lead time is shown on each product page). Please confirm all specs before checkout, since made-to-order items aren't eligible for returns, exchanges or refunds. Need help? Call 844-439-4335 or email info@casterhq.com and we'll verify fit for you.

Diameter: 4 inTread: 2 in
This collection gathers plate-mount casters used on warehouse carts on epoxy and smooth concrete. Typical builds show wheel diameters 4 in and polyurethane treads. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. Replace worn corners in matched sets when possible so the cart tracks straight under load. These medium-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.

2 options in this exact size and spec. See all casters by load capacity and mount type › or call 844-439-4335 for a cross-reference.
