4 in Stainless Steel Plate Mount Polyurethane Caster 770 lbs

Overview

This heavy-duty rigid caster is engineered for demanding industrial environments where corrosion resistance and high load capacity are critical. The unit features a 4-inch high-resilience polyurethane wheel mounted on a robust stainless steel fork, delivering a static load rating of 770 lbs. Designed specifically for washdown areas and food processing facilities, the construction resists rust and chemical degradation while maintaining structural integrity under significant weight. The thermoplastic polyurethane tread offers superior floor protection, preventing damage to delicate surfaces while ensuring quiet and smooth operation. With a plate mount configuration, this caster provides exceptional stability for equipment that requires straight-line movement without the need for swiveling.

Applications

Food and beverage processing plants Pharmaceutical manufacturing facilities Commercial kitchen equipment Chemical processing units Marine and offshore equipment Washdown and sterile environments Heavy-duty carts and industrial trailers Laboratory equipment transport This caster assembly is built to withstand rigorous daily use in wet, corrosive, or hygienic settings. The stainless steel construction eliminates the risk of contamination from rust or flaking paint, making it an ideal choice for regulated industries. The 4-inch wheel diameter strikes an optimal balance between maneuverability and the ability to roll over minor floor imperfections such as cracks or thresholds. The plate mount interface measures 4.5 by 3.9 inches, featuring four pre-drilled holes for secure attachment to various types of machinery bases or custom fabricated frames. The thermoplastic polyurethane compound used in the wheel formulation resists oils, greases, and common industrial solvents, ensuring long-term performance even when exposed to harsh cleaning agents. Whether utilized on stationary racks that require occasional repositioning or on active transport carts moving heavy loads across smooth concrete or epoxy floors, this rigid caster delivers reliable durability. The precision engineering of the axle and bearing system minimizes rolling resistance, reducing operator fatigue during manual pushing tasks. Its low-profile design with a 5.4-inch installation height allows for integration into equipment with limited ground clearance while still providing substantial lifting power.
