5" & 6" Casters
5-inch and 6-inch overstock casters are the workhorse industrial size, balancing roll, capacity, and clearance for carts, racks, and equipment. Verified surplus and closeout inventory, priced below comparable new.
Why 5"–6" is the default
This range rolls easily over thresholds and minor debris, carries medium to heavy loads, and fits most standard equipment. It is the most common industrial wheel size, available in nearly every tread and mount.
- Best all-around roll vs. capacity
- Handles thresholds and light debris
- Widest choice of tread and mount
- Medium to heavy duty
Buying 5"–6" overstock
Compare tread material, bearing, mount, and capacity across verified suppliers. Pallet and bulk lots ship by freight with cost shown up front.
Polyurethane or phenolic?
Polyurethane protects finished floors and rolls quietly; phenolic carries more and resists chemicals and heat but is harder on floors and louder.
Will 6 inch clear a threshold?
Generally yes for typical dock and door thresholds. For larger obstacles or rough yards, step up to 8"+ wheels.
