The stages in a bearing life cycle are extremely
important for achieving the maximum service life of the bearing. By
applying the right maintenance practices and using the correct tools, you
can considerably extend your bearing's service life and increase plant
productivity and efficiency.
Mounting and lubrication
Includes mechanical fitting tools, induction heaters and hydraulic
Mounting is one of the critical stages of the bearing's
lifecycle. If the bearing is not mounted properly using the correct method
and tools, the bearing's service lifetime will be reduced. Lubrication is
also an important step in the mounting procedure. Selecting bearing grease
suitable for the application is critical to achieving optimum performance.
Additionally, the quantity of grease and the lubrication method used can
positively influence the service life of the bearing.
Includes shaft and belt alignment tools and machinery shims
After the bearing has been mounted in an application,
such as a motor connected to a pump, the application should be aligned. If
the application is not properly aligned, the misalignment can cause the
bearing to suffer additional load, friction and vibration. These can
accelerate fatigue and reduce the bearing's, as well as other machine
components, service life. Furthermore, increased vibration and friction can
significantly increase energy consumption and the risk of premature
Includes bearing greases, manual and automatic lubricators and lubrication
When operating, the bearing requires correct re-lubrication
practices to optimise its performance. Selecting bearing grease suitable
for the application and applying the right quantities at correct intervals
are essential for achieving the maximum service life of the bearing.
Additionally, the re-lubrication method used can positively contribute to
optimising the bearing's service life. Continuous lubrication using
automatic lubricators, single or multiple-point, provides more consistent,
correct and contamination-free grease supply than manual re-lubrication
Basic condition monitoring
Includes temperature, noise, speed and vibration measuring
During operation, it is important to regularly inspect
the condition of the bearing by performing basic condition monitoring, such
as temperature, vibration and noise measurements. These regular inspections
will allow the detection of potential problems and help to prevent
unexpected machine stops. Consequently the machine maintenance can be
planned to suit the production schedule, increasing the plant's
productivity and efficiency.
Includes pullers, both mechanical and hydraulic, induction heaters and
At some point, the bearing will reach the end of its
service life and will have to be replaced. Although the bearing may not be
used again, it is extremely important to dismount it correctly so that the
service life of the replacement bearing is not compromised. Firstly, the
use of proper dismounting methods tools will help prevent damage to other
machine components, such as the shaft and housing, which are often re-used.
Secondly, incorrect dismounting techniques can be hazardous to the operator.
