Customized 100mm Cast Iron Caster Wheels 4 Inch Double Brake 4 Swivel Caster

Product Specification

4 Inch Red PU Iron Core Caster Wheel With Double Brake For Trolley And Equipment

Feature

This caster is a heavy-duty mobility solution engineered for demanding industrial applications, combining exceptional load capacity with comprehensive locking control. Its key physical and mechanical features include:

• 4-Inch Diameter & Red PU on Iron Core Wheel: The wheel measures 4 inches (approximately 100mm) in diameter. It features a red polyurethane (PU) tread bonded to a heavy-duty iron or cast iron core . This dual-material construction provides the shock absorption and floor protection of polyurethane with the immense strength and load-bearing capacity of metal.

• Double Brake System: The caster is equipped with a comprehensive braking mechanism. Based on industry standards, this "double brake" typically refers to either:

  • Total Lock Brake: A single pedal that locks both the wheel rotation and the swivel actionsimultaneously, ensuring complete immobility .

  • Combination System: Some configurations offer a side lock brake (locking the wheel hub) plus a separate swivel lock (converting the swivel to rigid), which together provide total lock functionality .

• Double Ball Bearings: The wheel hub contains double ball bearings . This precision bearing type ensures exceptionally smooth, low-friction rotation and can handle high radial and thrust loads, guaranteeing long service life under continuous heavy use. High-quality grease (such as molybdenum disulfide) is often used for durability .

• Swivel Function (360°): The caster features a full swivel bracket, typically made of heavy-gauge steel with a corrosion-resistant finish such as zinc plating . The swivel head incorporates precision ball bearings with hardened raceways for smooth directional changes even under heavy loads .

• Exceptional Load Capacity: A 4-inch red PU on iron core caster with double ball bearings is rated for heavy-duty applications. Load capacities typically range from 230 kg to 570 kg (approximately 500 lbs to 1,250 lbs) per caster, depending on the specific design and manufacturer .

• Standard Top Plate Mounting: Most models feature a standard top plate fitting for secure mounting to equipment frames, with common plate sizes around 100x113mm and bolt hole centers .

Functions

The primary functions of this caster are centered on providing powerful, reliable mobility and comprehensive control for heavy equipment:

Ideal Applications

Given its combination of massive load capacity, smooth-rolling double bearings, floor-protective PU tread, and comprehensive double brake system, this caster is ideally suited for the most demanding industrial, commercial, and institutional applications .

• Heavy Industrial Material Handling:

  • Heavy-Duty Platform Trucks: For transporting extremely heavy loads of parts, materials, and finished goods in warehouses, factories, and distribution centers .

  • Large Roll Cages and Transport Containers: For secure and efficient movement of bulk items in logistics and heavy manufacturing environments .

  • Automotive Assembly Line Carts: For moving heavy components, engines, and sub-assemblies along production lines .

• Industrial Machinery and Equipment:

  • Heavy Machine Tool Stands: For massive equipment like large presses, lathes, milling machines, and industrial generators that require mobility for repositioning but demand absolute stability during operation .

  • Portable Heavy-Duty Generators and Compressors: For industrial-grade generators, air compressors, and welding units that need to be moved into position for use and locked securely .

  • Heavy Workbenches and Maintenance Carts: For mobile workstations in fabrication shops, heavy equipment maintenance facilities, and assembly areas .

• Commercial and Institutional Heavy-Duty Use:

  • Large Catering and Food Service Equipment: For heavy food service trolleys, ingredient bins, and equipment racks in commercial kitchens and institutional catering operations .

  • Hospital Equipment and Medical Carts: For heavy medical equipment, patient transport systems, and supply carts in hospitals and healthcare facilities .

  • Theatrical and Stage Equipment: For moving heavy lighting trusses, speaker systems, and stage platforms that require quiet movement and secure positioning.

• Warehouse and Distribution Centers:

  • Pallet Dollies and Skid Movers: For maneuvering palletized loads in tight warehouse spaces.

  • Heavy-Duty Shelving and Racking Systems: For mobile storage systems that need to be repositioned for access while safely supporting massive weight.
