Both the disk spindle’s and the actuator’s bearing on the read / write head plays a key role in hard disk drives. After all, only durable bearings make for continuous and reliable hard disk drive operation. Whether you’re at the stage of creating new bearing types in the development process, are further developing existing bearings or are carrying out random checks during production – by measuring surface parameters, you can draw key conclusions for future production operations. You can therefore examine the influence that flatness parameters have on bearing performance or reliably check defined tolerances in production.
Surface measurement systems from Polytec, and specifically the models in the TopMap range of products, are well suited to this application and can be tailored exactly to your requirements. Why not try our solutions out for yourself?
