Shafts are commonly found in various industrial applications where rotational motion is required to transmit power or perform specific functions. These essential components can suffer issues such as wear and tear from vibration, rubbing, abrasive contaminants, and corrosion. In situations where it is impractical to strip a shaft, Belzona metallic polymers can repair in-situ, limiting the downtime and lost production costs without the risks that result from welding procedures. A step-by-step how-to guide: 00:00 Introduction 00:21 Undercut the substrate by a minimum of 0.06 inches (approx. 1.6mm) 00:31 Machine a rough thread profile to achieve a clean, rough bare metal 01:00 Degrease the prepared surface using Belzona 9111 or any other approved cleaner/degreaser 01:12 Apply 6-8 wraps of tape to both sides of the repair area to act as a thickness gauge 01:52 Belzona 1111 (Super Metal) – a two-part repair composite 02:07 Mixing ratio by volume: 3 parts base to 1 part solidifier 02:17 Mix thoroughly until a uniform, streak-free colour is achieved 02:30 Apply Belzona 1111, forcing it down into the surface using a brush to avoid air entrapment 03:06 Remove excess product and smooth out the surface 03:26 Remove the tape 03:48 Allow the product to fully cure 03:53 Machine the repair down to within 0.005 inches (125 microns) of the desired profile 04:32 Remove the final 0.002 inches (50-75 microns) using fine emery cloth 🛒 To purchase this solution, head to Belzona.com to contact your local Distributor: https://www.belzona.com/en/about/disfinder.aspx 📖READ OUR LATEST BLOG: https://blog.belzona.com/ CONNECT WITH US: On LinkedIn - / belzona FOLLOW US: On Instagram - / belzonaglobal
