XTB Bushings for Conveyor Pulleys and Weld-On Hubs
Spend enough time around conveyors and you learn quickly that reliability often comes down to the mounting system. When a pulley slips or a hub loosens, production does not slow down gracefully. It stops.
That is why XTB bushings are widely used in conveyor pulley assemblies and weld-on hub setups.
XTB bushings are heavy-duty QD-style tapered bushings designed to mount weld-on hubs, pulleys, and sheaves securely to a shaft. They are built for high torque capacity and strong clamping force, making them a dependable choice for material handling and bulk conveying applications.
At MDS of Michigan, we regularly help customers across West Michigan specify and replace these in conveyor builds and shutdown maintenance work.
How They Work in Pulley Assemblies
In a typical setup, the weld-on hub is attached to the pulley shell, and the XTB bushing provides the shaft connection. As the mounting bolts are tightened, the taper draws the bushing into the hub and grips the shaft evenly around its circumference.
This creates:
- Strong torque transfer
- Reduced shaft wear
- Minimal axial movement
- Balanced clamping force
- Easier installation and removal
The heavy barrel design and full hub engagement make them especially suited for conveyor loading conditions where shock and vibration are present.
Typical Applications
We most often see XTB bushings paired with:
- Conveyor pulleys
- Weld-on hubs
- Aggregate and bulk handling systems
- Food and packaging conveyors
- Processing and manufacturing lines
Anywhere torque loads are high and uptime matters, this mounting style shows its value.
Why Proper Selection Matters
A correctly sized bushing and hub combination protects shafts, prevents slippage, and reduces maintenance headaches. Small fitment errors can lead to vibration, wear, or premature failure. We work directly with maintenance teams and engineers to match bore size, shaft tolerance, and hub compatibility so installations go smoothly the first time.
If you are replacing components or building a conveyor assembly, our team at MDS of Michigan can help you identify compatible options quickly.
