Red 3 Inch Swivel Casters OEM 75mm Heavy Duty Castors Double Brake System

Product Specification

3 Inch Red Color PVC Caster Wheel with Iron Cap Outside, Double Ball Bearings and Double Brake System for Furniture and Equipments

Feature and Functional Purpose

• The primary purpose of this caster is to provide a durable, smooth-rolling, and highly stable mobility solution for furniture and medium-duty equipment, combining the load-bearing strength of PVC with reinforced durability and comprehensive locking.

  • 3-Inch Diameter & Red PVC Wheel: The 3-inch wheel with a red Polyvinyl Chloride (PVC) tread offers a balance of load capacity and maneuverability. PVC is a hard-wearing, impact-resistant material that provides good load-bearing capability while being resistant to oils, grease, and many chemicals. The red color is often used for visual identification in industrial or commercial settings.

  • Iron Cap Outside: This refers to a metal (iron) hub cap or reinforcement ring on the outer face of the wheel. The functional purpose is to provide additional strength and durability to the wheel hub, preventing the PVC material from deforming under heavy loads or impact. It acts as a protective shield, enhancing the wheel's longevity and load capacity.

  • Double Ball Bearings: This indicates precision bearings within the wheel hub. The "double ball bearings" design ensures exceptionally smooth and effortless rolling with minimal friction, even under significant load. They are engineered for maintenance-free operation and long service life in demanding applications, allowing the wheel to rotate freely around its axle .

  • Double Brake System: A comprehensive braking mechanism that typically locks both the wheel rotation and the swivel action simultaneously. This ensures the equipment remains completely immobile—preventing both rolling and swiveling—for maximum safety during use or when parked .

  • Swivel Function: The 360-degree swivel head (which often features its own precision ball bearings in the raceway) allows for easy steering and repositioning of equipment in tight spaces, essential for maneuvering in busy workshops, offices, or commercial areas .

• Functional Purpose: To safely and effortlessly move furniture and medium-weight equipment into precise positions, utilizing the reinforced PVC wheel and precision bearings for ease of use, and then engage the double brake to create a completely stable, immobile platform during operation, while the iron cap provides enhanced durability at the wheel hub.

Functional Benefits

The combination of the PVC wheel, iron cap reinforcement, double ball bearings, and double brake system provides significant operational advantages:
