Vibration Analysis in Deep Groove Ball Bearings: Velocity (V) vs. Acceleration (Z)
Jun 08, 2026
If you are manufacturing high-precision electric motors, you already know that bearing vibration is the enemy. It generates unwanted noise, increases operating temperatures, and ultimately shortens the lifespan of your product.
When your Quality Assurance team places a deep groove ball bearing on a vibration tester (such as a BVT instrument), they are typically presented with two primary metrics: Velocity (V) and Acceleration (Z).
But what exactly is the difference? And more importantly, if you are designing a high-speed, low-noise motor for drones, medical devices, or premium home appliances, which metric should you rely on?
As a manufacturer heavily invested in the R&D of ultra-quiet deep groove ball bearings, Welink Bearing has helped countless motor eng...
