Preface
This publication presents design examples covering
various machines, vehicles and equipment having one
thing in common: rolling bearings.
For this reason the brief texts concentrate on the roll-
ing bearing aspects of the applications. The operation
of the machine allows conclusions to be drawn about
the operating conditions which dictate the bearing
type and design, the size and arrangement, fits, lubri-
cation and sealing.
Important rolling bearing engineering terms are print-
ed in italics. At the end of this publication they are
summarized and explained in a glossary of terms, some
supplemented by illustrations.
