One of the most appealing characteristics of the Oldham coupling is its simplicity: three parts, no lubrication required (in polymer-disc versions), and no adjustment mechanisms to drift out of calibration. This simplicity extends to its maintenance requirements. A...

The coupling that connects a servo motor shaft to a ballscrew — a component that most machine operators never see and rarely think about — has an outsized influence on the positioning accuracy, repeatability, and long-term performance of a CNC machine. In modern...

With dozens of Oldham coupling variants available — spanning bore sizes from 3 mm to over 100 mm, disc materials from acetal to PEEK to steel, and hub styles from set-screw to clamp to keyed — selecting the right one for a specific application is not as...

Oldham couplings are among the most reliable components in a precision drive system. With no elastomeric elements to age, no springs to fatigue, and no lubrication passages to become blocked, they can operate for years without requiring attention. However, they are...

When engineers reach the coupling selection stage of a drive system design, the Oldham coupling and the jaw coupling (also known as the spider coupling or claw coupling) appear on the shortlist more often than almost any other type. Both are compact, affordable, and...

If you have ever tried to connect two shafts that are not perfectly aligned — and in the real world, they almost never are — you quickly discover that a rigid connection is not a solution. Rigid couplings transmit misalignment forces directly into the shafts and their...
