100mm Black PP Caster Wheel With Double Ball Bearings For Equipment

Feature

This caster is a robust, medium-duty mobility solution engineered for smooth rolling and durability in various industrial and commercial applications. Its key physical and mechanical features include:

• 100mm Diameter & Black PP Wheel: The wheel measures 100mm (approximately 4 inches) in diameter. It is made from high-quality black polypropylene (PP) , an impact-resistant thermoplastic with a hardness of approximately 60-65 Shore D . This material is known for its strength and high chemical resistance .
• Double Ball Bearings: The wheel hub contains double ball bearings . This precision bearing type is designed for smooth, low-friction rotation and can handle higher loads compared to plain bearings .
• Swivel Function (360°): The caster features a full swivel bracket, typically made of pressed steel with a zinc-plated and blue-passivated finish for corrosion resistance . The swivel head incorporates a double ball bearing raceway, ensuring smooth directional changes and increased service life .
• Top Plate Fitting: It is designed for mounting via a standard top plate, with common bolt hole spacings like 80 x 60mm .
• Load Capacity: A 100mm PP caster with double ball bearings typically supports dynamic loads in the range of 140 kg to 160 kg at 4 km/h, with static load capacities up to 400 kg .
• Operating Temperature: The wheel is generally suitable for temperatures ranging from -20°C to +60°C .

Functions

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

Ideal Applications

Given its combination of smooth-rolling bearings, durable PP wheel, and corrosion-resistant frame, this caster is ideally suited for a wide range of environments where equipment needs to be moved frequently.

• Industrial & Material Handling:
  • Platform Trucks and Dollies: For transporting parts, boxes, and materials in warehouses and factories .
  • Assembly Line Carts: For moving components and tools along production lines where low-effort rolling is required .
  • Workbenches and Tool Stands: For mobile workstations in workshops that need to be repositioned for different tasks .
  • Roll Cages: For secure transport of goods in logistics and retail environments .
• Commercial & Institutional Settings:
  • Catering Carts and Meal Delivery Systems: For food service operations where equipment is moved frequently and requires chemical resistance for cleaning .
  • Janitorial and Maintenance Carts: For housekeeping use in schools, offices, and hotels, where exposure to water and cleaning chemicals is common.
  • Mail Carts and Delivery Carts: For transporting packages and documents in offices and distribution centers .
  • Waste Disposal Equipment: For bins and containers that need to be maneuvered in back-of-house areas .
• Light Industrial Machinery:
  • Machine Construction: For smaller machinery and equipment that benefits from integrated mobility .
  • Portable Generators and Compressors: For units that need to be moved into position for use and stored away when not in operation.
  • Electronic Systems and Clean-Room Technology: In environments where non-marking and chemical-resistant properties are valued .
