NSK Case Study


Caster Turret

Cost Savings: $288,000

A steel mill asked NSK to evaluate the condition of their caster turret bearing. A NSK industry specialist evaluated the torsion values of the bolts and determined some had been elongated and needed to be re-torqued. Upon completion, NSK also performed a deflection test to evaluate the wear of the bearing in this critical component.

Key Facts

Application: Caster turret (Country: USA)
End-product: Steel
Problem: Studs on turret caster bearing were loose
Objective: Maintain bearing properly to increase life

Steel Mill

Value Proposals

NSK re-torqued several studs on a turret caster bearing
NSK also performed a deflection test to help evaluate the remaining life of this critical component
Spare studs needed to be ordered since they were not on site and require a long lead time
Downtime was reduced
