Bearings

Fast, Accurate, Data-Rich Non-Contact Bearing Measurements

Bearings are the fundamental components that allow the meticulous movement of machines found across all kinds of industries, from medical technology to industrial manufacturing. Our customers in this market need to optimise processes and improve productivity, whilst producing the most reliable and effective products possible- under tight budget constraints. So much depends on the role of the bearing, particularly as they can be exposed to challenging or hostile environments, where failure in the field and the associated recovery costs can risk the reputation of a company.

The advancement of Ceramic material is driving development to increase bearing life and reduce maintenance, however, challenges such as “C” cracks, surface imperfections and sphericity inspection means quality control is a fundamental requirement. Removing manual inspection and subjective quality is vital to this process, OmniLux 3D contactless technology is a very effective solution to ensuring your quality is in your control at all times.

Our ultra-precise, non-contact metrology technology can provide fast, detailed and highly accurate measurements that are data-rich. This provides the ability to understand the effects on bearing surfaces on a range of materials, ultimately improving reliability and life-cycle as well as predicting service requirements.

Conventional methods typically only allow a partial measurement of a wear scar. The images to the left show the results of RedLux 3D measurements on two components from a wear simulator for wind turbine gear box components, including all of the wear scar. The measurements were carried out with our optical CMM and took a few minutes to complete with resolutions of only a few nanometres. Being able to measure the complete wear scar gives the possibility of evaluating wear in the context of overall component form. It enables an understanding of failure modes that a simple 2D trace with a stylus instrument or a measurement over a small section of the wear scar cannot convey. (Data courtesy of nCATS).
