Basic Information

  • Available Sizes: 3″

  • Load Capacity: 500KG

  • This high-performance low profile polyurethane on cast iron caster wheel is engineered for heavy industrial applications requiring an ultra-low center of gravity combined with maximum floor protection. Featuring a rugged, shatter-proof cast iron core bonded with a premium high-durometer polyurethane (PU) tread, it delivers massive load capacities in a remarkably compact mounting height. This specialized design provides smooth, near-silent rolling and excellent shock absorption, making it the ultimate mobility solution for heavy machinery, automated production lines, and high-capacity industrial workstations.


Key Features

  1. Low Center of Gravity & High Stability: Minimizes overall equipment mounting height, lowering the center of gravity to prevent top-heavy machinery from tipping.

  2. Massive Load Capacity with Iron Core: The solid cast iron core provides extreme structural strength, ensuring the wheel can withstand intense static loads and heavy structural impacts without cracking.

  3. Floor Protection & Silent Rolling: The premium PU tread absorbs floor vibrations and dampens noise, rolling smoothly without scratching or leaving skid marks on epoxy, concrete, or tiled floors.

  4. Low Rolling Resistance & Oil Resistance: The high-grade polyurethane formula reduces manual pushing effort and safely resists workshop oils, grease, and mild industrial chemicals.

Where to Use Our Casters

  • Automotive Assembly Lines & Heavy Tooling: Smooth and secure movement for heavy parts racks, welding fixtures, and assembly dollies without tracking or damaging resin-coated factory floors.

  • Heavy-Duty Workbenches & Tool Cabinets: Keeps massive workstations low, ergonomic, and stable, while allowing operators to easily reposition them when layout changes are required.

  • AGVs & Factory Automation Platforms: Ideal for low-profile Automated Guided Vehicles and mobile robotic cells that require high weight capacities paired with shock absorption to protect sensitive electronics.

  • Heavy Industrial Enclosures & Power Supplies: Provides a highly reliable, compact transport base for high-capacity electrical cabinets, control panels, and generator enclosures.
