Product Description
3 Inch Black Color PVC Caster Wheel with Double Ball Bearings and Double Brake System for Furniture and Equipments
Feature
This caster is a durable, medium-duty mobility solution designed to offer smooth rolling and secure locking for furniture and equipment in various settings. Its key physical and mechanical features include:
| Feature | Technical Specifications |
|---|---|
| 3-Inch Diameter & Black PVC Wheel | The wheel measures 3 inches (approximately 75-80mm) in diameter. It is made from black Polyvinyl Chloride (PVC) , a hard-wearing, impact-resistant material that provides good load-bearing capability while being resistant to oils, grease, and many chemicals. PVC is known for its durability and quiet operation . |
| Double Ball Bearings | The wheel hub contains double ball bearings . This precision bearing type is designed for exceptionally smooth, low-friction rotation and can handle higher radial and thrust loads compared to single bearings or plain bearings, ensuring long service life under continuous use. |
| Double Brake System | The caster is equipped with a comprehensive braking mechanism. Based on industry standards, this "double brake" typically refers to a total lock brake—a single pedal that locks both the wheel rotation and the swivel action simultaneously, ensuring complete immobility . |
| Swivel Function (360°) | The caster features a full swivel bracket, typically made of pressed steel with a zinc-plated finish for corrosion resistance . The swivel head incorporates ball bearings for smooth directional changes . |
| Load Capacity | A 3-inch black PVC caster with double ball bearings typically supports medium-duty loads. Load capacities commonly range from 60 kg to 95 kg (approximately 130 lbs to 210 lbs) per caster, depending on the specific bracket and wheel design . |
| Standard Top Plate Mounting | Most models feature a standard top plate fitting for secure mounting to equipment frames. Common plate dimensions are approximately 92 x 63.5mm with bolt hole centers . |
Functions
The primary functions of this caster are centered on providing reliable mobility, smooth operation, and comprehensive control for furniture and equipment:
| Feature | Functional Benefit |
|---|---|
| Double Ball Bearings (in wheel) | Provides effortless rolling and superior load distribution. Significantly reduces rolling resistance, making equipment easy to maneuver with minimal operator fatigue, even under continuous use . |
| Double Brake System | Delivers maximum stability and safety by locking both the wheel and swivel. This prevents any unwanted movement, "creep," or swiveling, which is essential for equipment that must remain perfectly still during use, loading, or on level floors . |
| Black PVC Wheel | Offers a durable, non-marking rolling surface that resists chemicals, oils, and water. Provides good load capacity while protecting floors from damage and scuffs. PVC also operates quietly, making it suitable for noise-sensitive environments . |
| Smooth Swivel Action | Ensures easy maneuverability and precise positioning in tight spaces. The 360° rotation allows for easy navigation around obstacles and accurate alignment of equipment . |
| Zinc-Plated Steel Bracket | Provides corrosion resistance and structural integrity. Protects the metal frame from rust caused by humidity, moisture, and cleaning agents, extending the caster's service life . |
Ideal Applications
Given its combination of smooth-rolling double bearings, durable PVC wheel, and comprehensive double brake system, this caster is ideally suited for a wide range of furniture and equipment applications in commercial, institutional, and light industrial environments.
| Application Area | Specific Uses |
|---|---|
| Furniture and Office Applications | Ideal for heavy filing cabinets, bookcases, display cases, and storage cabinets that need to be moved occasionally for cleaning or reconfiguration, and then locked securely in place. Also suitable for office carts and AV stands . |
| Commercial and Retail Settings | For retail display fixtures, movable shelving, and store racks that require repositioning for floor plan changes. Suitable for supermarket shelving and restaurant equipment . |
| Institutional and Healthcare Facilities | For medical carts, equipment stands, hospital beds, and supply carts in hospitals and healthcare facilities where smooth mobility and secure locking are essential . Also suitable for library carts and book trucks in quiet reading areas. |
| Light Industrial and Workshop Equipment | For tool stands, service carts, workbenches, and maintenance equipment in workshops and light industrial settings. The double brake ensures stable positioning during use . |
| Hospitality and Food Service | For hotel housekeeping carts, catering equipment, and food service trolleys in restaurants and hospitality environments where quiet operation and reliable braking are valued . |
| Educational Institutions | For movable classroom furniture, AV equipment stands, library carts, and cafeteria service equipment in schools and universities . |
