Installing a flanged bronze bushing may look simple — just fit it in, right?
But in reality, even a small mistake during installation can dramatically shorten the bushing’s service life, cause abnormal noise, or even damage the entire assembly.
At TUYUE Bearing, we’ve seen how installation errors lead to avoidable failures. To help you get the best performance from your bushings, here are the five most common mistakes — and how to avoid them.
Many technicians make the mistake of hammering the bushing into place. While it might seem like a quick fix, this can deform the bushing surface or damage the flange.
The right way: Use a hydraulic or mechanical press to apply even pressure during installation. Never use impact tools.
If the housing bore or flange seat isn’t clean or level, the bushing won’t sit correctly — leading to vibration, uneven wear, or premature failure.
The right way: Clean all contact surfaces thoroughly before installation. Remove metal burrs, rust, and dust to ensure a smooth, even fit.
Installing without checking the shaft and housing dimensions is another costly mistake. A fit that’s too tight can cause cracks; too loose, and the bushing may rotate in the housing.
The right way: Always verify the recommended interference fit and tolerance before pressing in. Measure twice, install once.
Flanged bronze bushings often have specific lubrication grooves or oil holes. Installing the bushing backward or misaligning these features will block the lubrication path and cause dry running.
The right way: Double-check the orientation. The flange side should bear the axial load, and all lubrication holes or grooves must align properly with the design.
Even if everything looks fine after installation, skipping the test run can hide hidden issues like misalignment or excessive friction.
The right way: After installation, rotate the shaft manually to ensure smooth movement. Run the system at low speed and check for unusual noise, vibration, or temperature rise.
Proper installation isn’t just about fitting a part — it’s about ensuring long-term reliability and performance. By avoiding these five mistakes, you can extend the life of your flanged bronze bushings and reduce maintenance costs.
At TUYUE Bearing, we provide not only high-quality self-lubricating and bronze bushings but also the technical support you need to install them right the first time.
