3 Inch Yellow PP Caster Wheel With Double Ball Bearings For Equipment

Feature

This caster is engineered for medium-duty applications, combining precision movement with corrosion resistance. Its key physical and mechanical features include:

• 3-Inch Diameter & Yellow Color Wheel: The wheel measures 3 inches in diameter. The "Yellow" color is not merely aesthetic; in industrial and commercial settings, colored casters are often used for load rating identification or to denote specific material properties. It typically indicates a high-quality Polypropylene (PP) or a specialized engineered plastic wheel.
• Double Ball Bearings: The wheel hub contains two precision-ground ball bearing races. This is a significant upgrade from single or plain bearings, designed to handle higher radial and thrust loads while minimizing rotational friction.
• Swivel Function (360°): The caster features a full swivel top plate or stem, allowing the attached equipment to be steered in any direction. The swivel raceway itself often contains hardened ball bearings for smooth and durable rotation.
• Blue-White Zinc Resistant Coating: The entire metal frame (yoke, swivel head, and mounting plate) is treated with a blue-white zinc plating. This is an electrolytic galvanization process that creates a thin, sacrificial layer of zinc to protect the underlying steel from oxidation and rust.
• Material Composition (Implied): Based on the color and common industry standards, the wheel material is likely a tough, wear-resistant thermoplastic (such as Polypropylene or Nylon), chosen for its strength and chemical resistance.

Ideal Applications

Given its combination of smooth-rolling bearings, corrosion-resistant frame, and durable wheel, this caster is ideally suited for environments where equipment needs to be moved frequently and exposed to typical industrial or commercial conditions.

• Industrial Machinery & Carts:
  • Assembly Line Carts: For transporting parts and components in manufacturing plants, where smooth rolling and durability are required.
  • Tool Stands & Service Carts: For mechanics and technicians who need to move heavy toolboxes or service equipment to a job site.
  • Platform Trucks: For general material handling in warehouses and factories.
• Commercial & Food Service (Back-of-House):
  • Ingredient Bins & Trolleys: For moving bulk ingredients in kitchens or bakeries, where the zinc coating offers protection against humidity.
  • Janitorial Carts: For housekeeping use in schools, hotels, and hospitals, where exposure to water and cleaning chemicals is common.
  • Light-Duty Kitchen Equipment Racks: For shelving units holding dry goods or supplies.
• Institutional Settings:
  • Mail Carts & Delivery Carts: In offices or distribution centers, requiring quiet, efficient movement.
  • Medical Equipment Stands (Non-Surgical): For portable diagnostic equipment or supply carts in general hospital wards where smooth mobility is valued.
