Heavy-Duty Polyurethane Casters
Item 00K2131, Heavy-Duty Polyurethane Swivel Caster w/Brake, 3″ × 4″ (100kg)
These are tough, dependable casters in a range of sizes. Resistant to grease, oil, adhesives, kerosene-based solvents and UV, the solid polyurethane tires are extremely durable and non-marring.
They have polypropylene hubs and 0.10″ thick zinc-plated steel bases; slow-rolling ball bearings in the axle ensure smooth, controlled operation.
Available in two versions: a fixed caster, and a swivel locking caster that rotates on a ball-bearing race and has a foot-operated brake mechanism.
On the three largest sizes, the brake simultaneously locks the wheel and swivel base; on the 2″ size, it locks the wheel only.
Nominal sizes listed are wheel diameter by overall height, with weight capacity in brackets.
