Stainless Steel Shaft Sleeve Adapter

About this item

Material: Crafted from stainless steel, this stainless steel shaft sleeve adapter features a smooth silver-colored metal surface and a rigid cylindrical body built for consistent performance in mechanical assemblies.
Function: This shaft adapter is designed to adapt a 3/4-inch shaft to a 1-inch pulley or wheel bore, enabling compatibility between mismatched shaft and bore sizes without replacing existing components.
Design: The shaft sleeve adapter has a cylindrical body with a longitudinal slot, a 1/4-inch keyway, and compact dimensions of approximately 58 mm in length and 25 mm in outside diameter for a fit.
Included Components: This shaft adapter with key comes with a matching 45 mm long, 3/16-inch wide key that locks into the keyway to prevent slippage and maintain reliable rotational force transfer between parts.
Application: This adapter is suitable for use with motor shafts, pneumatic crankshafts, pulleys, gears, and gear reducers, supporting machinery repairs, retrofit projects, and drive-system maintenance tasks.

When you are working drivesystem system repair or a machinery retrofit project, finding the right fit between shafts and pulleys can slow down progress. This stainless steel shaft sleeve adapter offers a practical, cost-effective solution by connecting the difference between a 3/4-inch shaft and a 1-inch pulley or wheel bore, so you can keep existing components in service instead of investing in full replacements. Built with a smooth silver-colored stainless steel body, the shaft adapter delivers reliable rigidity and wear resistance for long-term use in mechanical setups. Its cylindrical form and compact dimensions — roughly 58 mm in length and 25 mm in outside diameter — allow it to fit neatly into pulley bores while maintaining proper alignment with the shaft. A longitudinal slot runs along the body to accommodate slight dimensional variations and support a secure, pressdesign installation. As a shaft adapter with key, it includes a 45 mm long, 3/16-inch wide key that pairs with the built-in 1/4-inch keyway to lock the assembly as one This keyed connection prevents rotational slippage between the shaft and the pulley, ensuring consistent rotational force transfer even under varying load conditions. Whether you are working on a small motor upgrade or a larger gearbox adjustment, the keyed design adds an extra layer of reliability to the connection. The shaft sleeve adapter is versatile enough for a wide range of mechanical applications. It works with motor shafts, pneumatic crankshafts, pulleys, gears, and gear reducers, making it a useful addition to any maintenance kit or workshop inventory. Instead of sourcing custom-machined parts or replacing good pulleys, you can use this adapter to resolve size mismatches quickly. Overall, this adapter is a straightforward, dependable solution for pulley size adaptation and drive system maintenance. Its stainless steel construction, keyed design, and sizing combine to provide secure fit that supports smooth, efficient power transmission across many common mechanical setups.
