For the large bearings supporting machinery and equipment in the metal making, paper making, mining and quarrying operations, the severity of operating stresses often leads to the onset of damage long before bearings acheive their calculated life.
Whether it is instigated by contamination or conventional fatigue mechanisms (metal-to-metal) contact), many of these cases of early bearing damage can be foreseen and contingency planning can be implemented.
Namely, adopting a reconditioning program to extend the viable service life of these bearing assets.
NSK owns and operates our Reconditioning Service Center in Alliance, Ohio, providing a wide array of reconditioning and bearing modification services.
For more information, contact NSK.
Reconditioning services can range from polishing and minor repairs to regrinding raceways and replacing components. Not all bearings can be restrored and put back to use. Operating conditions may be too severe, damage may to too profound.
From the outset, NSK performs a rigourous analysis to evaluate a bearing potential for successful reconditioning to like-new specifications. Additionally, we work with our customers to identify root causes of damage in order to create and implement corrective or preventative maintenance measures.
Our range of recondition services includes:
Candidacy for reconditioning is typically viable for a wide range of large-size bearings including:
For steel mill applications in particular, NSK reconditioning services are widely employed for:
