100mm Yellow Color Double Ball Bearings Swivel Caster Wheel with Blue-white Zinc Resistant Coating For Machine And Equipment

Features & Functional Purpose

• Core Features:
  • Wheel Diameter: 100mm .
  • Wheel Color & Material: Yellow Polyurethane (PU/TPU) tread. This is often bonded to a sturdy core made of materials like cast iron or die-cast aluminum . (Note: A yellow PP wheel was not found in the search results).
  • Caster Type: Swivel, featuring a precision double ball bearing raceway in the swivel head for smooth and effortless steering .
  • Bearings: The wheel itself is equipped with precision ball bearings for smooth rolling .
  • Coating: The steel fork and housing feature a zinc-plated, blue-passivated finish. This is a specific treatment (often Cr6-free) that provides a durable, attractive, and corrosion-resistant surface .
• Functional Purpose: This caster is designed for heavy-duty industrial and commercial applications. The swivel mechanism with double ball bearings allows for precise maneuverability and direction changes. The yellow polyurethane wheel combines the floor-protection and quietness of rubber with the durability and load capacity of hard materials. The blue-white zinc coating protects the metal components from rust and corrosion, ensuring a long service life in demanding environments.

Functional Benefits

1. Superior Corrosion Resistance: The blue-white zinc passivated coating provides excellent protection against rust and oxidation, making the caster suitable for environments with moisture, cleaning agents, or humidity.
2. Exceptional Manoeuvrability: The double ball bearing swivel raceway ensures the caster turns smoothly and easily under load, reducing operator effort when steering equipment.
3. High Load Capacity & Durability: Casters with these specifications are built for heavy loads. For example, similar models have load capacities ranging from 180kg to 295kg or more . The robust construction withstands shock and impact loads.
4. Floor-Friendly & Quiet Operation: The yellow polyurethane tread is non-marking, gentle on all types of flooring, and operates with very low noise compared to hard plastic or metal wheels . It also offers excellent abrasion resistance and good chemical resistance.
5. Smooth Rolling: The precision ball bearings in the wheel itself minimize rolling resistance, making it easier to move heavy loads.

Ideal Applications

Given its robust features, this type of caster is ideal for a wide range of demanding applications:
