NSK RECONDITIONING SERVICES
from Critical Assets
NSK provides our customers with the best possible opportunity to maximize bearing life cycles and minimize downtime with sustainable solutions. In continuous casting and rolling mills, the severity of applications can lead to the onset of damage resulting from contamination or metal-to-metal contact that prevents bearings from achieving their calculated life. In many of these instances, the fatigue of the bearing can be foreseen – if not prevented – and the effective service life of the bearing can be extended through a service program to recondition bearings to like-new specifications.
Successfully reconditioned bearings can be returned to service, or into critical-spare inventory, thereby:
|Extending the life of the bearing|
|Reducing replacement costs|
|Eliminating long lead times|
|Optimizing inventory utilization|
From the outset, NSK performs an exhaustive damage analysis to evaluate a bearing’s potential for successful reconditioning and to identify root causes of damage in order to assist our customers with implementing corrective or preventative maintenance measures. For bearings suitable for reconditioning, NSK’s range of services include:
|Inspection, with damage analysis report|
|Verification of raceway, bore, inner / outer rings, cup, cone, inner, outer and roller angles|
|Provision of new components (rolling elements, pins and cage rings) as required|
|Polishing, vibratory finishing|
|Verifying and resetting clearances measured|
|Preserving, lubricating, packaging for long-term storage|
Candidacy for reconditioning is typically viable for a wide range of large-size bearings including:
|Spherical roller bearings|
|Tapered roller bearings – single and multi-row|
|Cylindrical roller bearings – single and multi-row|
|Deep groove ball bearings|
For steel mill applications in particular, NSK reconditioning services are widely employed for:
|Caster bearings – spherical and cylindrical roller bearings|
|Work roll bearings – multi-row tapered roller bearings|
|Back-up roll bearings – multi-row cylindrical and tapered roller bearings|
|Slewing ring bearings|
