GMN Paul Mller Industrie Co KG High
Minimal tolerances for dimension shape and running accuracy produce maximum performance capability long service life and are defined by international (ISO 492) and national (DIN 620) standards GMN high precision ball bearings are produced in precision classes P4–P2 as well as ABEC 7–ABEC 9
BEARING IN MIND: PRECISION BALL BEARING BASICS
ABOVE AND BEYOND BARDEN ABEC TOLERANCES PRECISION BEARINGS ABEC tolerance classes are useful in bearing selection By specifying ABEC 7 for example the design engineer is able to pinpoint a standardized level of beanng precision However ABEC classes are not all-inclusive in defining bearing precision

Super Precision and Spindle Bearings Selection Guide
Most super precision bearings and spindle bearings carry a high quality-rating such as ABEC-7 or ABEC-9 and run coolly and smoothly at high speeds Annular Bearing Engineers' Committee (ABEC) ratings are used to define different accuracy and tolerance ranges for bearings As a rule the higher the ABEC number the tighter the bearing tolerance
