Heavy Duty Swivel Caster 6" PU-on-iron-core Wheel 350kg Load For Heavy Condenser Transport

6 Inch Heavy Duty Caster – Dual-Spring Shock Absorbing PU-on-Iron-Core Wheel, 350kg Load, 6203 Bearing, Dust-Protective Lid

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.

1. Commercial Laundry & Dry Cleaning Facilities
   • Industrial washing machines & dryers – shock absorption protects internal drums and bearings
   • Laundry carts & trolleys – straight-line tracking between washing, drying, and folding stations
   • Linen chutes & collection bins – heavy loads on wheels, smooth transport
   • Ironing & pressing stations – vibration isolation for steam presses
2. Large Home Appliance Manufacturing & Transport
   • Washing machine assembly lines – movable dollies for chassis during production
   • Refrigerator & freezer transport – floor protection with non-marking PU wheels
   • Dishwasher & oven installation – temporary mobility during fitting and servicing
   • HVAC & air conditioning units – heavy condenser transport
3. Industrial Equipment & Machinery
   • Industrial ovens & kilns (cool side) – heat-resistant options available
   • Conveyor system feed carts – fixed-direction material flow
   • Generator & compressor housings – vibration-damping during operation
   • Medical imaging equipment – stable positioning with shock isolation
4. Institutional & Commercial Use
   • Hotel laundry rooms – high-throughput cart movement
   • Hospital linen services – hygienic, easy-to-clean wheels
   • School & university facilities – durable carts for maintenance and catering

We understand that every application is different. As a factory-direct manufacturer, we offer:

📩 Contact us with your requirements – we'll engineer a caster solution that fits your exact application.

• High-temperature above +120 °C continuous – choose phenolic or steel wheels
• Outdoor rough terrain / gravel – pneumatic tires recommended
• Prolonged direct sunlight / UV – unless UV-stabilized PU specified
• Slippery or oily floors – consider anti-static or specialized tread
• Speeds exceeding 4–6 km/h – designed for controlled manual movement
• Tight turning radius – rigid bracket cannot turn; pair with swivel casters

📩 Contact us today for factory-direct pricing, technical drawings, and customization options.

Whether you need standard or fully customized casters for laundry equipment, heavy appliances, or industrial machinery—we engineer solutions that last.
