engineering team gained a deeper appreciation for the role that high-precision components play in motion-critical systems.
“This story highlights what we believe at Ruland,” says Gumas. “Ruland parts are not cheap, and we know this. The value of a Ruland part is not in our ability to provide the lowest overall cost; it is our ability to provide the most value. In this story, there are three things we do that no one else does: stamp our name and bore size on the part, precisely control face-to-bore
perpendicularity, and the groove identifying the work surface of the collar. These are not our only differentiators, but in a critical application like this, the Ruland collar does not fail. The cost savings on a shaft collar are trivial compared to the tens of thousands of dollars this customer had to spend to fix the error.” The case serves as a reminder that
component performance isn’t always obvious on the surface. Shaft collars may seem like low-priority hardware, but when used in linear motion systems, precisionmatters – and cutting corners can be far more expensive than investing in quality up front.
In mechanical design, every detail matters – even the ones that look simple. Precision facing may sound like a small feature, but in real-world applications, it can mean the difference between system stability and costly failure. For this OEM, a well-intentioned substitution resulted in a $30,000 mistake. For others, it’s
a reminder: when your application depends on precision, make sure your components are built to deliver it.
