The Durastar 3/8-24" OD x 3" Length Plain Axle is a premium axle solution engineered for reliability and seamless integration with Durastar’s 04 Series casters. Designed with precision threading and durable construction, this axle ensures a secure and stable fit across a wide range of light to medium-duty caster applications.
With a choice between a standard plain nut or a high-performance nylon insert nut, users can select the configuration that best suits their needs—whether for simple assemblies or vibration-sensitive environments requiring extra locking power.
This finely machined axle features a 3/8"-24 outer diameter and a precise 3-inch length, delivering consistent thread engagement and alignment. Crafted from high-strength steel, it stands up to wear, stress, and repeated use in professional environments. Its refined design not only reduces downtime during replacements but also minimizes operator error during installation.
Whether you're outfitting carts, material handling racks, or general-use mobile equipment, the Durastar axle ensures load stability and dependable motion, even in industrial settings. Available protective finishes also offer added defense against corrosion for extended service life.
Choose the nylon insert nut option for improved vibration resistance and locking strength. This is particularly beneficial for mobile units exposed to dynamic loads or frequent movement. The insert helps prevent loosening over time, enhancing long-term reliability without the need for constant re-tightening.
Specifically tailored for compatibility with Durastar 04 Series casters, this axle simplifies replacement and upgrade processes. It offers an ideal fit and finish for OEMs, maintenance teams, and industrial engineers looking to ensure consistency in build quality and operational performance.
Durastar delivers exceptional components built with accuracy, integrity, and long-term value in mind.
