| High Light | heavy duty swivel caster 6 inch wheel ，PU-on-iron-core caster 350kg load ，heavy duty caster for straight-line towing | ||
Engineered for heavy appliances and commercial laundry facilities, this 6-inch rigid caster features a dual-spring suspension system, polyurethane tread on an iron core, and 6203 precision bearings. Rated for 350 kg per caster, it absorbs vibration, protects floors, and ensures stable straight-line movement. Fully customizable in wheel material, temperature range, and load capacity to match your exact specifications.
Dual-Spring Protection for Heavy Equipment.
Our 6-inch Rigid Heavy Duty Caster is purpose-built for environments where large appliances, commercial washing machines, industrial dryers, and laundry processing lines demand both stability and vibration control. The dual-spring steel suspension plate acts as a shock absorber, reducing the impact of uneven floors and protecting sensitive equipment internals from vibration damage.
The polyurethane (PU) tread is bonded to a solid iron core, delivering a non-marking, wear-resistant rolling surface with the structural strength to handle 350 kg per caster. The 6203 deep-groove ball bearings ensure smooth, low-friction rotation under heavy loads. The fixed rigid bracket provides straight-line tracking—essential for towed laundry carts and appliance dollies.
A dust-protective lid shields the spring mechanism from lint, detergent powder, and workshop debris, extending service life in demanding environments. The 5 mm thick galvanized steel bracket and top plate resist rust and deformation, while the 140 × 110 mm mounting plate with 105 × 78 mm bolt hole spacing fits standard industrial equipment.
As a factory-direct manufacturer, we offer full customization: wheel material (PU, rubber, nylon, phenolic), temperature rating (-30 °C to +120 °C options), and load capacity tuning. Whether you need casters for a commercial washing machine, industrial oven, or medical imaging equipment, we can engineer the right solution.
