Features

• Wheel Diameter: 4 inches (100mm) – A versatile medium size that offers a good balance of clearance and ease of movement.

• Material: High-Quality Rubber (Tread) – Typically molded onto a hard polypropylene or nylon center.

• Color: Full Black (consistent color throughout the rubber compound, preventing color fade).

• Bearing Type: Double Ball Bearings – Precision-ground bearings housed within the wheel hub. This is a significant upgrade from plain bore or sleeve bearings.

• Type: Swivel (360° rotation) with a heavy-duty top plate or stem mounting option.

• Construction: Features a sturdy metal frame (often zinc or chrome-plated) with a hardened raceway to support the swivel action.

Functional Benefits

• Superior Load Distribution & Smooth Rolling: The double ball bearings reduce friction between the axle and the wheel. This allows the caster to start rolling more easily under heavy loads and maintain momentum with less effort compared to single-bearing or plain-bore wheels.

• Shock Absorption & Floor Protection: The soft, high-quality rubber tread acts as a cushion. It absorbs vibrations and shock from uneven floors, protecting sensitive equipment and reducing noise. It is also non-marking, ensuring it won't leave scuff marks on floors.

• High Maneuverability: The swivel action, combined with the low-friction bearings, allows for effortless 360° steering. This makes it easy to navigate heavy equipment through tight corners.

• Enhanced Durability: The double bearing design distributes the rotational force evenly, reducing wear and tear on the wheel hub. This extends the lifespan of the caster significantly in high-use applications.

• Grip and Traction: The rubber material provides excellent traction on wet or smooth surfaces, preventing the equipment from sliding or drifting during movement or when stationary.

This caster is best suited for environments where load capacity, smooth movement, and quiet operation are required simultaneously.

• Industrial Machinery: Ideal for heavy-duty equipment like generators, compressors, large tool boxes, and assembly line feeders that need to be positioned precisely.

• Material Handling: Perfect for heavy-duty platform trucks, warehouse carts, and tow lines where rolling resistance needs to be minimized despite heavy loads.

• Audiovisual & Events: Used for speaker cabinets, amplifier racks, and heavy lighting trusses. The rubber absorbs vibration (preventing speaker rattle) and the bearings ensure smooth rolling even with heavy amp racks.

• Medical & Healthcare: Suitable for heavy medical equipment (like X-ray machines or dialysis machines) that needs to be moved quietly and smoothly between rooms.

• Janitorial & Maintenance: Ideal for heavy floor scrubbers, burnishers, or large waste bins that are constantly in motion and require smooth steering.
