A key element of the service is the provision of technical
support throughout the life cycle of a product, from initial
concept through design and testing to the analysis of
bearings returned from the field.

The support function divides itself
into four areas:

G Bearing Design
G Metrology
G Testing
G Bearing Damage Diagnosis
