3 Inch Red PP Caster Wheels With Double Ball Bearings And Brake System

Product Specification

3 Inch Red Color Double Ball Bearings Caster Wheel with Double Brake System and Blue-white Zinc Resistant Coating For Machine And Equipment

Features Analysis

• Wheel Diameter – 3 Inches (75mm):
  A compact yet versatile size that balances low profile with sufficient roll‑over capability for minor floor imperfections. Suitable for a wide range of equipment and machinery.

• Red Color:
  The red finish (typically on the wheel tread or the entire wheel) often indicates a polyurethane (PU) tread, though it may also denote a rubber compound. Red is commonly used for high‑visibility safety identification or for distinguishing heavy‑duty casters in industrial environments.

• Double Ball Bearings:
  The caster is equipped with two precision ball bearings:
  – One in the swivel head to ensure smooth, effortless 360° rotation.
  – One in the wheel hub to minimize rolling resistance.
  This combination delivers superior maneuverability, even under load, and reduces maintenance needs.

• Double Brake System:
  A total‑lock mechanism that engages both the wheel (prevents rolling) and the swivel section (prevents swiveling) with a single pedal or lever. The equipment remains completely stationary when the brake is applied, eliminating any unintended movement.

• Blue-White Zinc Resistant Coating:
  The metal components (top plate, swivel housing, fork, and brake mechanism) are finished with a blue‑white zinc electroplating. This provides:
  – Corrosion resistance against moisture, humidity, and mild chemicals.
  – Durability against rust and oxidation, extending the caster’s service life in demanding environments.
  The “blue‑white” appearance offers a clean, professional look.

• Typical Construction:
  The wheel is often a polyurethane (PU) tread bonded to an iron or steel core, combining the floor‑friendly softness of PU with the load‑carrying strength of metal. This is consistent with the red color and heavy‑duty positioning.

Functional Benefits

• Exceptional Maneuverability:
  Double ball bearings ensure the caster swivels instantly and rolls with minimal effort, even under heavy loads. This reduces operator fatigue and allows precise positioning of equipment.

• Total Lock Safety:
  The double brake system locks both rolling and swiveling, making the equipment rock‑solid when parked. Critical for applications where stability is required during loading, maintenance, or use on inclines.

• Long Service Life in Harsh Conditions:
  The blue‑white zinc coating protects steel components from rust, corrosion, and environmental exposure. This caster can withstand washdowns, humidity, and chemical splashes better than uncoated or painted alternatives.

• High Load Capacity in a Compact Size:
  The combination of a metal‑cored wheel (typically iron) and robust swivel construction allows the 3‑inch caster to support significant loads (often 200–350 lbs per caster) without increasing equipment height.

• Floor Protection & Quiet Operation:
  If equipped with a polyurethane tread (as typical with red casters), the wheel is non‑marking, absorbs vibration, and rolls quietly—ideal for finished floors and noise‑sensitive areas.

• Low Maintenance:
  Sealed ball bearings require no lubrication, and the corrosion‑resistant coating eliminates the need for painting or rust prevention.

Ideal Applications

This caster is best suited for medium‑ to heavy‑duty machinery and equipment where a combination of easy mobility, positive locking, and resistance to corrosion is required.

• Industrial Machinery & Equipment
  – Mobile machine bases (presses, saws, conveyors)
