The lubrication of rolling bearings –
similar to that of sliding bearings – mainly
serves one purpose: to avoid or at least
reduce metal-to-metal contact between
the rolling and sliding contact surfaces,
i.e. to reduce friction and wear in the
Oil, adhering to the surfaces of the
parts in rolling contact, is fed between the
contact areas. The oil film separates the
contact surfaces preventing metal-to-metal
contact (»physical lubrication«).
This handbook is intended to help engineers in industry
with the operation and maintenance of machinery. It
gives the information that these engineers need in a
form that is instantly accessible and easy to read.
The manufacturers of machinery provide guidance on
the operation, lubrication and maintenance required for
their particular machines.
Bearings (both plain and rolling element) are used as important supporting elements for locating rotating components and confining their motion in desired direction. In order to ensure their operational reliability and desired life, these need to be properly designed/selected for an application more so because of ever increasing operational speeds. This requires the careful performance evaluation of different types of bearings considering aspects such as thermal stability, lubrication, contaminants in lubricants and controlling mechanism etc....
Machinery reliability management in the process industries can be
divided into three phases: equipment selection and pre-erection reliability
assurance, preparation for effective startup, and post-startup reliability
assurance and maintenance cost reduction. All of these phases are important;
they are intertwined and merit equal attention. The techniques and
procedures described in this text cover essential elements of each phase;
they have been critically examined and have led to substantially
improved reliability and maintenance efficiencies.
