The Durastar 1/2-13" Zerk Axle with a 3-3/8" overall length is engineered for high-performance and dependable use in a wide range of caster assemblies. Designed to deliver secure, long-lasting performance, this axle is a preferred choice for professionals maintaining or assembling Durastar caster Series 30, 34, 35, 40, and 46.
This axle features a built-in Zerk fitting, allowing for easy and efficient lubrication. Regular maintenance through the Zerk grease port not only reduces friction but also significantly extends the service life of both the axle and wheel. Whether in industrial warehouses, commercial facilities, or custom mobility builds, this component ensures continued reliability.
Customers can choose between two 5/16" jam nut options-with or without a nylon insert. The nylon-inserted nut provides extra resistance to loosening caused by vibration, making it ideal for applications with high movement or load stress. This flexibility gives maintenance teams the ability to match hardware to specific use-case requirements.
Crafted from durable, corrosion-resistant materials, the Durastar axle resists wear and environmental damage, supporting continuous performance in harsh operating conditions. It ensures proper wheel alignment, reduces mechanical stress, and supports safe and quiet operation across a variety of applications.
Whether you're outfitting a new caster system or replacing worn components, the Durastar Zerk Axle delivers a professional-grade solution. With its precise threading, compatibility across multiple series, and user-friendly maintenance access, it’s a trusted axle choice for industrial engineers, repair teams, and OEM applications.
Backed by Durastar’s proven engineering quality, this axle and jam nut configuration ensures your caster systems remain efficient, safe, and operational-day after day. Choose a component that enhances both performance and reliability.
This caster runs a Nylon wheel. Nylon resists chemicals and moisture and carries high loads, which suits washdown and wet environments.
Rated for -20°F to 180°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).
The Nylon wheel performs best on smooth, hard industrial floors. For non-marking or clean-environment needs, ask us about matching tread options.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
