Custom Bearing Test Rig & Dimensional Gauge Manufacturing

Develop your company’s own in-house bearing testing capability with NES's Custom Bearing Test Rig & Dimensional Gauging manufacturing.

We design and build bearing test rigs of all sizes and types to meet OEM needs. Rigs can be outfitted with manual or fully automated controls to help you assess bearing efficiency, fatigue life, wear and material characteristics, as well as lubricant analysis. Advancements in bearing technology and the evolution of the global supply chain underscore the value of in-house bearing testing.

NES also offers bearing and application support to solve complex bearing design and bearing test conditions. Whether a new or existing design, give the bearing the respect it deserves and contact us to aid in proper bearing selection. Our support for new equipment can significantly help to improve manufacturing reliability.
