What are the benefits of custom bearings? What advantages do they give engineers and the companies for which they work?
Custom bearings let engineers design and use components tailor-made for their specific applications. Such bearings can have longer working lives or better resist corrosion, thanks to bearing material chosen to resist contaminants in an application’s working environment. This reduces replacement and maintenance costs. Custom bearings can be produced with greater load ratings than ‘standard’ selections. They can also be made smaller or lighter to make installation easier. And from a market perspective, they can capture aftermarket replacement business for the OEM.
