6in x 2in Heavy Duty Cast Iron Plate Casters Set of 4 - 1250 lb Each

Our review of these 6in x 2in industrial casters finds them best suited for workshops and warehouse use where durability and load capacity matter most. The bottom line: buyers who need a compact, heavy duty caster with a cast iron hub and galvanized steel wheel will appreciate the long service life and high load rating. The review focuses on construction, capacity and typical applications, and concludes these casters are a practical choice when moving heavy platform trucks, U-boat carts or welding carts on relatively rough floors.

Key Features

• Industrial grade construction: The mixed steel and cast iron hub plus a zinc plated yoke deliver corrosion resistance and durable structure for frequent heavy use.
• High load capacity: Each caster is rated up to 1250 lb, providing dependable support when used as a set of four on heavy equipment.
• Robust wheel design: The bright galvanized steel wheel with abrasion resistance stands up to wear on wood and concrete floors.
• Serviceable axle: The Zerk axle and 12' ID spanner bushing allow for greaseable bearings to extend service life under heavy loads.
• Wide temperature tolerance: Cast iron components tolerate extreme temperatures, making these casters suitable for demanding industrial environments.

Who It's For

These casters are primarily for industrial users who need plate-mounted wheels on dollies, platform trucks, warehouse carts and heavy workbenches. They work well for fabricators, shipping departments and maintenance crews who move heavy loads that are not shifted constantly but require reliable support.

Those looking for quiet, floor-friendly or non-marking casters for delicate flooring, frequent repositioning, or light residential use should consider softer wheel materials instead; these cast iron hub casters perform best on rough wood or concrete and prioritize strength over floor protection.

Pros & Cons

Pros

• Very high per-caster load capacity that allows heavy platform trucks to be fitted confidently.
• Durable mixed steel and cast iron construction provides long service life and good shock absorption.
• Galvanized steel wheel and zinc plating reduce surface rust and abrasion in industrial settings.
• Serviceable roller bearings and Zerk lubrication point simplify maintenance.

Cons

• Cast iron hubs and steel wheels are not ideal for protecting delicate floors and can be noisy compared with softer wheel compounds.
