4 Inch Full Black TPR Swivel Caster Wheel With Single Ball Bearing

Product Specification

4 Inch Full black TPR Swivel Caster Wheel With Single Ball bearing For Equipment

Feature and Functional Purpose

1. Full Black TPR (Thermoplastic Rubber) Wheel: The black color and TPR material indicate a soft, rubber-like wheel. The functional purpose is to provide excellent shock absorption, quiet operation, and floor protection. TPR is naturally non-marking and grippy, preventing damage to floors and reducing noise.
2. Single Ball Bearing: The wheel hub contains a single ball bearing. The functional purpose is to reduce rotational friction, allowing the wheel to roll smoothly. While not as heavy-duty as double bearings, a single bearing provides a cost-effective solution for light to medium-duty applications where smooth rolling is still required.
3. Swivel or Rigid Design (Assumed General Purpose): While not specified as "Fix" or "Swivel," a caster of this type is commonly available in either configuration. The functional purpose is to provide mobility; swivel versions allow for steering, while rigid versions provide straight-line stability.
4. Blue-white Zinc Resistant Coating: This is a protective electroplated finish applied to the metal frame (yoke and top plate). The functional purpose is to provide corrosion and rust resistance. The "blue-white" bright finish protects the metal from moisture, chemicals, and general wear, extending the caster's lifespan.

Summary of Functional Benefits

• Ultra-Quiet and Gentle Operation: The soft TPR material ensures the caster rolls almost silently, making it ideal for noise-sensitive environments. It also protects delicate flooring surfaces (like hardwood, tile, or polished concrete) from scratches, dents, and scuff marks.

• Smooth and Cost-Effective Mobility: The single ball bearing reduces pushing effort compared to plain bore wheels, offering a balance of smooth performance and affordability for lighter equipment.

• Shock and Vibration Absorption: TPR acts as a cushion, absorbing vibrations and shocks from uneven floors. This protects the equipment's contents (especially sensitive electronics) and reduces operator fatigue.

• Corrosion Resistance: The blue-white zinc coating ensures the metal frame remains rust-free and visually appealing even in slightly humid environments, preventing unsightly rust stains on floors.

• Versatile Traction: The TPR material provides good grip on various floor surfaces, reducing the risk of slipping or sliding, especially on slightly wet or smooth floors.

Ideal Applications

Given its combination of quiet operation, floor protection, and cost-effectiveness, this caster is ideally suited for:

1. Medical and Healthcare Equipment: Perfect for hospital beds, patient trolleys, medical carts, and IV stands where quiet, gentle movement is critical for patient comfort.
2. Office and Hospitality Furniture: Ideal for office chairs, equipment stands, serving carts, and display fixtures in hotels, restaurants, and retail spaces where floor protection and aesthetics are priorities.
3. Light Industrial Carts and Material Handling: Suitable for light-duty utility carts, tool stands, and assembly line trolleys in workshops with finished floors where noise reduction is desired.
4. Residential and Commercial Furniture: Great for moving heavy furniture, shelving units, or entertainment centers without damaging home flooring.
5. Electronics and Sensitive Equipment Racks: The shock-absorbing properties help protect delicate electronic equipment from vibrations during movement.
