With a weight capacity of 220kg (485 lb) per caster, these have the highest load rating of any casters we offer. They have bases formed from heavy-gauge laminated steel plate, with cast aluminum hubs and tough non-marring polyurethane tires that are resistant to grease, oil, adhesives, kerosene-based solvents and UV.
Available as fixed casters in two sizes; the larger size is also available as a locking swivel caster that rotates on a ball-bearing race and has a lever-operated brake mechanism that simultaneously locks the wheel and the rotating base.
The 100mm (just under 4") diameter casters are 146mm (5 3/4") tall, with a 96mm × 112mm (3 13/16" × 4 7/16") mounting plate; 150mm (just under 6") casters are 190mm (7 1/2") tall with a 100mm × 117mm (3 7/8" × 4 1/2") mounting plate. M10 or 7/16" bolts required (not included).
