4‑Inch Stainless‑Steel Red PU Rigid Caster

4 Inch Rigid Fixed Caster, Stainless Steel Bracket, Red PU Wheel, Medium‑Duty Industrial Caster

Product Overview

This 4‑inch fixed rigid caster is built with premium stainless‑steel bracket and high‑performance red PU wheel. Without swivel function, it only moves straight forward, delivering stable linear travelling performance. The stainless‑steel structure offers excellent rust‑proof property, perfectly suitable for humid, wet, corrosive working environments such as food workshops, cleaning equipment and marine‑related facilities. The red PU tread ensures quiet rolling, floor‑protection and outstanding wear resistance for medium‑load applications.

Main Materials

• Wheel Tread: High‑elastic red PU (Polyurethane), non‑marking, wear‑resistant
• Wheel Core: Reinforced hard plastic core, impact‑resistant, anti‑deformation
• Bracket & Top Plate: Stainless‑steel, anti‑rust, anti‑corrosion
• Fasteners: Stainless‑steel hardware

Key Features

✅ Stainless‑steel fixed bracket Rigid non‑rotating stainless‑steel bracket, great anti‑rust performance, ideal for damp or corrosive working conditions. Provides stable straight‑line movement, prevents unintended turning.
