Stainless Steel Double Spring with Aluminum Core & Polyurethane Wheel Heavy-Duty Caster
- Material Composition:
- Housing: 304/316 stainless steel (corrosion-resistant, suitable for harsh environments)
- Spring System: Dual spring shock absorption (reduces impact by 40-60% compared to single spring)
- Wheel Core: Aluminum alloy (lightweight yet high load capacity)
- Wheel Surface: Polyurethane (non-marking, abrasion-resistant, hardness 85-95A)
- Specialized Design:
- Sealed ball bearings (IP54 rating, dust/water-resistant)
- Bolt-hole or swivel mounting options
- Optional brake systems (side-lock or total-lock)
