Back to Casters

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.

3-1/8 x 4-1/8 inch top-plate casters for bake carts, metalworking fixtures, and debris-heavy floors. Typical builds show wheel diameters 3 to 8 in, polyurethane, phenolic, and nylon treads, and capacities 125 to 1,250 lb. Bring plate and stem measurements when replacing unmarked casters so the new corners sit level. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade.

Medium Duty Casters: buying guide

Medium duty casters carry up to 1,250 lb per caster — the everyday range under service carts, utility rigs, shop carts, and the warehouse equipment that moves all day. It's the tier where the caster has to be genuinely durable but the load still lets a four-caster set roll comfortably by hand.
