Description

When you’re setting up pulleys for a PTO-driven implement or rigging up a belt system on older equipment, having the right hub makes all the difference. This X-Series hub with a 7/8-inch bore gives you a solid mounting point that won’t slip or wobble when things are spinning at full speed. It’s the kind of component that looks simple but does an important job keeping your belt-driven systems running smooth and reliable.

What You’re Getting

  • Precision 7/8-inch bore that fits snugly on your shaft without play or movement
  • X-Series design that’s been proven in agricultural applications for years
  • Sturdy construction that handles the vibration and stress of field equipment
  • Universal design that works with a wide range of pulleys and sheaves

Built for Real Farm Work

This hub works great for everything from grain elevator drives to hay equipment belt systems. Whether you’re running a conveyor, powering a fan, or driving any belt-operated implement, this hub provides the solid connection between your shaft and pulley that keeps everything turning together. It’s particularly handy for custom fabrication work or when you need to repair older equipment that uses standard bore sizes.

Made to Last

The X-Series has earned its reputation for reliability in farm applications. This hub is built to handle the constant starting, stopping, and varying loads that come with agricultural work. The bore is machined to tight tolerances so you get a secure fit that won’t loosen up over time, even with the vibration from unbalanced loads or rough field conditions.

Installation Notes

Make sure your shaft diameter matches the 7/8-inch bore exactly – a loose fit will cause problems down the road. Clean both the shaft and hub bore before installation, and use the appropriate key and keyway setup to prevent slipping. A little anti-seize compound on the shaft makes future removal much easier if you need to service the system.
