SKF Maintenance and Lubrication Products

Basic condition monitoring
Basic condition monitoring is essential for achieving maximum bearing service life
To help ensure long bearing service life, it is important to
determine the condition of machinery and bearings while
in operation. Good predictive maintenance will help reduce
machine downtime and decrease overall maintenance costs.
To help you achieve the maximum service life from
your bearings, SKF has developed a wide range of
instruments for analysing the critical environmental
conditions which have an impact on bearing and
machine performance.

Run to failure
Run to failure occurs when repair action is not taken until a problem
results in machine failure. Run to failure problems often cause
costly secondary damage along with unplanned downtime and
maintenance costs.

Preventive maintenance is similar to the regular service of a car.
Often, unnecessary maintenance is performed.
Preventive maintenance
Preventive maintenance implies that a machine, or parts of a
machine, are overhauled on a regular basis regardless of the
condition of the parts. While preferable to run to failure maintenance,
preventive maintenance is costly because of excessive downtime from
unnecessary overhauls and the cost of replacing good parts along
with worn parts.

Predictive maintenance
Condition monitoring/predictive maintenance is the process of
determining the condition of machinery while in operation. This
enables the repair of problem components prior to failure. Condition
monitoring not only helps plant personnel reduce the possibility of
catastrophic failure, but also allows them to order parts in advance,
schedule manpower, and plan other repairs during the downtime.
With condition monitoring, machinery analysis takes two overlapping
forms: predictive and diagnostic.
Condition based maintenance means repairs are only carried
out when required.
