2.5in Trolley Castors 2.5 Inch Swivel Casters 65mm Wheel Diameter

Features Analysis

• Wheel Diameter – 2.5 Inches (65mm):
  A compact size that minimizes the mounting height, allowing equipment to sit low to the ground for stability. Small enough for tight spaces yet capable of rolling over minor floor irregularities.

• Material – Polypropylene (PP):

  • Gray Color: Typically indicates a non-marking tread suitable for finished floors. Gray is also a neutral, professional appearance common in industrial and medical equipment.

  • PP Construction: A rigid, lightweight thermoplastic that is resistant to water, oils, solvents, and many chemicals. It does not absorb moisture and will not rust.

  • Hard Tread: Provides very low rolling resistance and high durability on smooth surfaces, though it offers less shock absorption than rubber or TPR.

• Double Ball Bearings:
  The caster incorporates two ball bearings—usually one in the swivel head (for smooth rotation) and one in the wheel hub (for low-friction rolling). In some designs, “double ball bearings” may refer to a double-row bearing in the swivel for extra stability. Either configuration results in superior maneuverability and reduced maintenance compared to plain‑bore or single‑bearing casters.

• Swivel Caster Design:
  Mounted via a top plate or stem, allowing 360° rotation. The double‑bearing swivel ensures consistent directional response even under load.

Functional Benefits

• Exceptional Maneuverability:
  The double ball bearings (swivel + wheel) provide ultra‑smooth steering and rolling. Equipment can be easily turned, repositioned, or pushed with minimal effort, even in confined spaces.

• Low Rolling Resistance:
  Hard polypropylene tread combined with a precision wheel bearing reduces the force required to move loads. This is especially beneficial for equipment that is frequently repositioned.

• Non-Marking & Floor Friendly:
  Gray PP is non‑marking and will not leave scuffs or streaks on tile, hardwood, epoxy, or polished concrete floors.

• Corrosion & Chemical Resistance:
  Polypropylene is impervious to water, rust, and many industrial chemicals (oils, mild acids, cleaning agents). This makes the caster suitable for environments where washdowns or chemical exposure occur.

• Compact & Low Profile:
  The 2.5″ diameter keeps the overall equipment height low, improving stability and allowing machinery to fit under workbenches or into storage areas.

• Durable & Maintenance‑Free:
  Sealed ball bearings reduce the need for lubrication, and the PP wheel will not absorb moisture or swell. The hard tread resists flat‑spotting and abrasion on smooth floors.

Ideal Applications

This caster is best suited for light‑to‑medium duty equipment and machines where compact size, smooth mobility, and corrosion resistance are required.
