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.

Bearings - Calculation Tools

supports you with following bearing calculation tools:

  • Bearing life (NSK ABLE / ISO 281)
  • Bearing fits and clearances
  • Bearing frequencies
  • Load:
    Required minimum load for Cylindrical Roller Bearings
    Maximum permissible axial loads for Cylindrical Roller Bearings
  • Frictional moment, reference and thermal permissible speed:
    Frictional moment
    Reference speed (ISO 15312:2003) and thermal permissible speed
  • Lubrication:
    Grease replenishing interval
    Reference kinematic viscosity

NSK Verify App

NSK has launched a free app primarily for precision bearings for machine tools.
Scan 2D barcodes printed on NSK bearing boxes to assess bearing authenticity and access inspection reports online.

The app enables easier factory automation and IT-based plant management. CSV and PDF export of key information empowers customers to track usage history, improve product traceability, and even simplify bearing selection.

*Note: Only bearings with an “N” marked at the bottom right of the 2D barcode are currently supported.
