Description
If you’ve ever noticed your belt-driven equipment slipping or wobbling, a worn-out pulley hub might be the culprit. This X-series hub connects your pulleys to 1-3/8 inch shafts with a precise 21-spline fit that keeps everything running true and smooth. Whether you’re running hay equipment, conveyors, or any belt-driven machinery, this hub locks your pulley tight to the shaft so power transfers efficiently where you need it.
What You’re Getting
- Precision 21-spline bore that matches 1-3/8 inch agricultural shafts perfectly
- X-series design that’s compatible with a wide range of pulleys and equipment
- Quality construction that handles the constant vibration and stress of belt-driven systems
- Direct replacement hub that installs without modification or adapters
- Reliable connection that prevents slipping and maintains proper belt tension
Built for Real Farm Work
This hub fits a variety of belt-driven agricultural equipment where 1-3/8 inch 21-spline shafts are common. You’ll find these setups on hay balers, mower conditioners, conveyor systems, and feed equipment that rely on belt drives to transfer power efficiently. The 21-spline design provides more engagement points than smaller spline counts, making it ideal for applications that see varying loads and speeds.
Made to Last
Farm equipment hubs take a beating from constant rotation, belt tension, and the shock loads that come with field work. This X-series hub is built with quality materials that resist wear and maintain their grip on the shaft even after thousands of hours of operation. The precise machining ensures a tight fit that won’t develop play over time.
Installation Notes
This hub slides right onto your 1-3/8 inch 21-spline shaft and locks in place with set screws or pins depending on your setup. Make sure to clean any old grease or debris from the shaft splines before installation for the best fit. A light coat of anti-seize on the splines makes future removal easier if you need to service the equipment.
