4 Inch Orange Color PVC Caster Wheel with Anti-dust ring, Double Ball Bearings and Double Brake System for Furniture and Equipments

Feature

This caster is a specialized mobility solution designed for environments where cleanliness and maintenance prevention are priorities. Its key physical and mechanical features include:

• 4-Inch Diameter & Orange PVC Wheel: The wheel measures 4 inches (approximately 100mm) in diameter. It is made from orange Polyvinyl Chloride (PVC) , a hard-wearing, impact-resistant material that provides good load-bearing capability while being resistant to oils, grease, and many chemicals. The orange color is often used for visual identification in commercial or institutional settings.
• Anti-Dust Ring: This is the defining feature of the caster. The anti-dust ring is a protective shield (usually made of rubber, felt, or a flexible plastic) mounted on the swivel raceway (the joint between the top plate and the yoke). Its purpose is to prevent dust, lint, hair, and debris from entering the swivel mechanism's ball bearings or raceway.
• Swivel Function (360°): The caster features a full swivel top plate or stem, allowing attached furniture or equipment to be steered in any direction for excellent maneuverability.
• Load Capacity: A 4-inch PVC caster is typically rated for medium-duty applications. Common load ratings range from 100 kg to 200 kg per caster, depending on the specific bracket and wheel design.
• Durable Bracket: The bracket is typically constructed from pressed steel, often zinc-plated for corrosion resistance. The swivel head contains ball bearings for smooth rotation.

Functions

The primary functions of this caster are centered on providing reliable mobility while actively protecting the moving parts from contamination:

Ideal Applications

Given its combination of a durable PVC wheel and the protective anti-dust ring, this caster is ideally suited for environments where dust, fibers, and debris are present and equipment must remain easy to maneuver.

• Textile and Garment Industry:
  • Garment Racks and Clothing Rails: In retail stores, dry cleaners, and textile factories where lint and fabric fibers are abundant. The anti-dust ring prevents fibers from wrapping around the swivel mechanism .
  • Fabric Storage Carts: For moving bolts of fabric in warehouses and workshops.
• Healthcare and Institutional Settings:
  • Hospital Beds and Stretchers: In patient rooms and hallways where dust and hair are present. The anti-dust ring ensures smooth, quiet movement over the long term .
  • Medical Carts and Equipment Stands: For IV poles, monitor stands, and supply carts that must remain easy to steer despite exposure to airborne particles.
  • Library Carts: For book trucks in libraries where paper dust and fibers can accumulate and jam standard casters.
• Commercial and Hospitality Environments:
  • Hotel Housekeeping Carts: For linen and supply carts that collect dust and fibers during use in hallways and guest rooms .
  • Retail Display Fixtures: For movable shelving and display racks in stores where dust from products and foot traffic can accumulate.
  • Restaurant and Catering Equipment: For service carts and mobile furniture in back-of-house areas where food dust and debris are present.
• Light Industrial and Workshop Applications:
  • Woodworking Shop Carts: For mobile workbenches and material carts in woodworking shops where sawdust is a constant issue. The anti-dust ring prevents sawdust from jamming the swivel .
  • Tool Stands and Service Carts: In workshops and maintenance facilities where airborne dust and debris are common.
