65mm 2.5 Inch Ring Caster Black PVC Caster Wheels Double Brake System

Product Specification

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

Feature and Functional Purpose

1. Black PVC (Polyvinyl Chloride) Wheel: The 2.5-inch (approximately 65mm) diameter wheel is made of durable PVC material . The functional purpose is to provide smooth rolling with reliable load capacity while being non-marking, ensuring it won't leave scuff marks on floors . PVC wheels offer good durability and resistance to flat-spotting under load.
2. Anti-dust Ring (Thread Guard): The caster is equipped with an anti-dust ring (also called thread guard or dust cover) that protects the internal bearings . The functional purpose is to prevent dust, lint, threads, and debris from entering and clogging the bearing mechanism, ensuring long-term smooth operation and reducing maintenance needs in environments where fibers or contaminants are present .
3. Double Ball Bearings: The caster features double ball bearings in the swivel mechanism . The functional purpose is to ensure smooth 360° rotation and effortless maneuverability, even when supporting furniture and equipment weighing up to 60 kg (132 lbs) per caster . This design significantly reduces pushing effort and ensures long-term reliable performance.
4. Double Brake System: The caster features a comprehensive braking mechanism that locks both the wheel rotation and the swivel movement simultaneously . The functional purpose is to provide complete stability when the equipment is stationary—preventing movement and ensuring precise positioning.
5. Swivel Plate Design with Zinc Coating: The caster features a swivel top plate with zinc-plated surface finish for corrosion resistance . The functional purpose is to enable easy directional changes while protecting the metal frame from rust and moisture.

Summary of Functional Benefits

1. Extended Service Life in Contaminated Environments: The anti-dust ring provides critical protection by preventing dust, lint, and debris from entering the bearing mechanism . This ensures smooth operation even in environments with fibers or particles, reducing maintenance frequency and extending caster life.
2. Complete Stability and Safety: The double brake system provides comprehensive locking—both the wheel and the swivel are secured . This ensures furniture and equipment remain stationary during use, preventing accidents and providing reliable positioning.
3. Smooth and Effortless Maneuverability: The double ball bearings allow for heavy equipment to be moved and steered with minimal physical effort, improving workflow efficiency and reducing operator fatigue .
4. Floor Protection: The non-marking PVC material ensures flooring surfaces (hardwood, tile, laminate, epoxy) remain free from scuffs, scratches, and black marks .
5. Corrosion Resistance: The zinc-plated finish protects the metal frame from rust and moisture, ensuring long-term durability .
6. Compact and Versatile Size: The 2.5-inch diameter offers a balance of load capacity (60kg/132lbs) and low profile, making it suitable for furniture and equipment where space is limited .

Ideal Applications

Given its combination of dust protection, complete locking stability, compact size, and floor protection, this caster is ideally suited for:

• Healthcare and Medical Equipment: Perfect for hospital beds, medical carts, and patient room furniture where dust and lint from bedding and fabrics can be an issue. The anti-dust ring prevents fibers from clogging the casters, ensuring reliable performance .
• Office Furniture: Ideal for office chairs, filing cabinets, workstations, and conference tables where quiet movement, floor protection, and secure locking are essential .
• Textile and Garment Industry Equipment: Excellent for rolling racks, garment carts, and textile handling equipment where lint and thread debris are prevalent. The anti-dust ring is critical for preventing bearing contamination .
• Hospitality and Institutional Furniture: Suitable for housekeeping carts, service trolleys, and portable furniture in hotels, schools, and institutions where durability and floor protection are required .
• Light Industrial Carts and Equipment: Great for tool stands, utility carts, and light industrial equipment in workshops and manufacturing environments .
• Retail Displays and Fixtures: Perfect for display racks, shelving units, and merchandising carts that need to move easily while staying securely in place when positioned .
• Residential Furniture: Ideal for heavy furniture pieces like cabinets, bookcases, entertainment centers, and plant stands that require occasional mobility without damaging home flooring .
