An animal slaughter production line was experiencing regular failures of deep groove ball bearings used in a bleed shackle roller application which is used to transport animals along the production line. The initial bearings were replaced regularly resulting in high costs.
NSK engineers checked the application, analysed several failed bearing sets and found the cause of failure to be brinelling damage during operation.* NSK advised a different bearing type and assembly that could accommodate the impact loads seen during operation. The bearing change resulted in a significantly longer bearing operational lifetime.
