Dia 75mm Caster U Bracket OEM Heavy Duty Casters With Brakes

Product Specification

3 Inch White PP Material Swivel Caster Wheel With U-plate For Machine

Features & Functional Purpose

• Wheel Size & Material:

• • Feature: 3-inch diameter wheel constructed from White Polypropylene (PP).
  • Functional Purpose: The PP material provides a hard, smooth rolling surface with low rolling resistance. The white color is often specified for hygienic or aesthetic reasons (non-marking and clean-looking). The 3" size offers a balance between ground clearance and load distribution, making it easy to maneuver over flat surfaces without snagging on small debris.

• Swivel Mechanism:
  • Feature: Full 360-degree swivel action (typically with double ball raceways).
  • Functional Purpose: Allows the caster to rotate freely, enabling the attached equipment to change direction instantly. This provides superior maneuverability compared to rigid casters, making it easy to steer carts and machinery in tight spaces.
• Mounting:
  • Feature: "U-Plate" (Top Plate) mounting bracket.
  • Functional Purpose: The universal top plate (usually a standard 2-5/8" x 3-5/8" or 2-3/4" x 3-3/4" pattern with slotted holes) allows for easy bolting or screwing onto the bottom of machinery, equipment legs, or cart frames. The slotted holes accommodate minor misalignment during installation.
• Material Characteristics (PP):
  • Feature: Non-marking and chemically resistant tread.
  • Functional Purpose: Ensures the wheels do not leave black marks or scuffs on warehouse floors, tile, or finished concrete. It is also resistant to oils, solvents, and water, protecting the wheel integrity in industrial environments.

Summary of Functional Benefits

• Floor Protection: The white Polypropylene (PP) material is non-marking, ensuring it will not leave scuff marks or gray streaks on light-colored or finished flooring surfaces.
• Smooth & Quiet Operation: Provides a harder tread than rubber, making it easier to push/pull (low starting force) while remaining quieter than steel wheels.
• Superior Maneuverability: The 360° swivel action allows operators to change direction with minimal effort, reducing operator fatigue and improving workflow efficiency in confined spaces.
• Easy Installation: The universal U-plate design allows for quick retrofitting onto existing machines or straightforward assembly on new equipment using common tools.
• Corrosion & Chemical Resistance: PP material does not rust and withstands exposure to moisture, chemicals, and cleaning agents, ensuring longevity in washdown areas or chemical labs.
• Cost-Effective: PP is a durable yet economical material, offering a high-performance-to-cost ratio for light-to-medium industrial applications.

Ideal Applications

This type of caster is best suited for environments where floor cleanliness and maneuverability are priorities, and the loads are light to medium.

• Medical & Healthcare: Ideal for hospital beds, medical equipment stands, IV poles, and service carts where hygiene and floor protection are critical.
• Food Service: Suitable for bakery racks, utility carts in commercial kitchens, or catering equipment where white/non-marking wheels are required by health codes.
• Light Industrial: Perfect for small parts bins, electronic equipment racks, platform trucks, and tool stands in assembly lines.
• Retail & Display: Used on portable displays, clothing racks, and shelving units in showrooms where floors are polished and aesthetics matter.
• Laboratories: Applied under chemical carts or equipment stands due to the PP material's resistance to chemical spills.
