NSK Calculation Tools

The Cost Saver tool helps to identify all bearing related costs now and with an improved NSK solution in order to compare and calculate the total cost saving.

The Cost-Benefit Analysis looks at the total maintenance costs of a machine and calculates a break-even point for implementing a new bearing solution. This allows understanding when a machine with a new solution achieves the pay back point and starts to reduce overall maintenance costs.
