Yellow 5 Inch Office Chair Casters 125mm Trolley Wheels With Brakes

Product Specification

5 Inch Yellow Color Double ball bearings PP Swivel Caster Wheel For Industrial Machine and Equipment

Feature

This caster is a heavy-duty mobility solution engineered for demanding industrial environments, combining high load capacity with smooth maneuverability. Its key physical and mechanical features include:

• 5-Inch Diameter & Yellow PP Wheel: The wheel measures 5 inches (125mm) in diameter, providing excellent ground clearance and the ability to roll smoothly over uneven surfaces and small debris. It is made from high-quality yellow polypropylene (PP) , a tough, impact-resistant thermoplastic known for its strength, rigidity, and high chemical resistance . The yellow color is often used for visual identification in industrial settings, sometimes indicating specific load ratings or material grades .

• Double Ball Bearings: The wheel hub contains double ball bearings . This precision bearing type is designed for exceptionally smooth, low-friction rotation and can handle higher radial and thrust loads compared to single bearings or plain bearings, ensuring long service life under continuous use.

• Swivel Function (360°): The caster features a full swivel bracket, typically made of heavy-gauge steel with a corrosion-resistant finish. The swivel head incorporates precision ball bearings in the raceway, allowing for 360° rotation and effortless steering even under heavy loads . This enables omnidirectional movement and precise positioning.

• Load Capacity: A 5-inch PP caster with double ball bearings is typically rated for medium to heavy-duty industrial applications. Based on industry standards, load capacities for this size and configuration commonly range from 180 kg to 350 kg per caster, depending on the specific bracket and wheel design .

• Durable Construction: The bracket is usually constructed from pressed or forged steel, often zinc-plated for corrosion resistance. The PP wheel is non-marking and resistant to oils, greases, water, and many chemicals, making it suitable for harsh environments.

Functions

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

Ideal Applications

Given its combination of large diameter, smooth-rolling double bearings, durable PP wheel, and high load capacity, this caster is ideally suited for a wide range of heavy-duty industrial applications .

• Industrial Material Handling:
  • Heavy-Duty Platform Trucks: For transporting large, heavy loads of parts, materials, and finished goods in warehouses, factories, and distribution centers.
  • Roll Cages and Large Carts: For secure and efficient movement of bulk items in logistics, retail, and manufacturing environments.
  • Assembly Line Trolleys: For moving heavy components and sub-assemblies along production lines where smooth, low-effort rolling is essential for workflow.
• Industrial Machinery and Equipment:
  • Machine Tool Stands: For heavy equipment like large grinders, presses, lathes, and milling machines that require mobility for repositioning but must be stable during operation.
  • Portable Generators and Compressors: For heavy-duty industrial generators, air compressors, and welding units that need to be moved into position for use and stored securely when not in operation.
  • Heavy Workbenches and Maintenance Carts: For mobile workstations in fabrication shops, maintenance facilities, and assembly areas that need to support significant weight.
• Commercial and Institutional Heavy-Duty Use:
  • Large Catering Carts 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 .
  • Workshop and Manufacturing Environments: For general-purpose mobility in workshops, factories, and production facilities where durability, chemical resistance, and high load capacity are required .
