• [Military-Grade Durability]: Built with polyurethane treads and cast iron cores, these heavy duty casters withstand extreme conditions in air cargo operations and defense facilities without cracking or deformation. Operates from -40°F (cold storage) to 250°F (foundries)
• [4000 Lbs Capacity That Won't Let You Down]: Move heavy machinery like Bridgeport mills (avg. 1,800 lbs) and CNC lathes with confidence - each caster holds 1,000 lbs, totaling 4,000 lbs per set. Our dual-ball-bearing swivel mechanism maintains stability even when hauling uneven loads, preventing the dangerous "wheel wander" common in cheap casters. Independent lab tests verify: These industrial plate casters maintain 98% load capacity after 100,000+ rotations.
• [Silent Warehouse Warriors]: Noise-reducing PU wheels cut decibel levels by 60% vs nylon casters. the caster wheel adopts Roller Bearing, which increases the load capacity and durability, making the caster wheel with low friction resistance, high speed limit, and easier to move. Coupled with the 360-degree swivel top plate, you can easily change any direction you want with a little effort.
