Gray 2.5 Inch Swivel Casters 65mm Heavy Duty Trolley Wheels Customized

Product Specification

Features Analysis

• Wheel Diameter – 2.5 Inches (65mm):
  Compact size providing a low mounting height for equipment stability. Small enough for tight spaces, yet capable of rolling over minor floor irregularities.

• Material – Polypropylene (PP):

  • Gray Color: Non-marking tread that protects finished floors; neutral appearance suitable for professional environments.

  • PP Construction: Rigid, lightweight thermoplastic with excellent resistance to water, oils, solvents, and many chemicals. It does not rust, absorb moisture, or require painting.

• Double Ball Bearings:
  Typically includes a ball bearing in the swivel head for smooth 360° rotation and a separate ball bearing in the wheel hub for low‑friction rolling. This combination delivers superior maneuverability and consistent performance under load.

• Double Brake System:
  A total‑lock mechanism that simultaneously engages:

  • Wheel brake – prevents rolling.

  • Swivel brake – locks the caster’s rotation.
    The system is typically activated by a single pedal or lever, ensuring the equipment remains completely stationary when parked.

• Swivel Caster Design:
  Mounted via a top plate (usually 1.5″–2″ square) or stem, allowing multidirectional movement. The double brake ensures rigid positioning when engaged.

Functional Benefits

• Superior Maneuverability:
  The double ball bearings provide effortless steering and rolling, even with moderate loads. Equipment can be repositioned easily in confined workspaces.

• Total Lock Safety:
  The double brake eliminates both rolling and swiveling, preventing equipment from drifting, pivoting, or moving unintentionally. This is critical for tasks requiring absolute stability—such as loading, servicing, or operating machinery.

• Floor Protection:
  Gray PP is non‑marking and will not scratch or stain tile, hardwood, epoxy, or polished concrete. The hard tread does not pick up debris that could cause floor damage.

• Corrosion & Chemical Resistance:
  Polypropylene resists rust, moisture, oils, and mild cleaning agents, making the caster suitable for environments where washdowns or chemical exposure occur.

• Low Rolling Resistance:
  The hard PP tread combined with precision wheel bearings minimizes the effort needed to move equipment, reducing operator fatigue.

• Compact & Stable:
  The 2.5″ diameter keeps the equipment low to the ground, improving stability and allowing it to fit under workbenches or into storage areas.

• Maintenance‑Free:
  Sealed ball bearings require no lubrication, and the PP wheel will not swell or degrade from moisture or mild chemicals.
