Poor lubrication
is the reason for
of prematurebearing failures
36%
© SKF Group
36% of all premature bearing failures are related to poorlubrication
Poor lubrication can be:
Incorrect intervals• under-greasing• over-greasing
Incorrect lubricant selection• poor quality lubricant• lubricant type is unsuitable for the
application
Contamination• impurities can mix with the lubricant• poor handling (e.g. dirt on grease fitting)

Contamination

Lubrication
• The right grease• The right quantity• The right lubrication method
© SKF Group
Typical lubrication mistakes
Wrong lubricant choice:
• Problematic: people lubricate more (they think that solvesthe problem);excessive leakages etc.
Wrong filling degree:• Heat generation, churning, lubricant failure
Over-greasing:• Problematic at high speeds: internal heat generation
© SKF Group
Maintaining cleanliness when lubricating bearings is very importantto avoid early bearings failures.

Advantages of SKF automatic lubricators
Main savings with SKF automaticlubricators:
1. Improved maintenancepractices
Resources for re-lubricationcan be transferred to morecrucial maintenanceactivities resulting in betterutilisation of themaintenance staff - hencebetter uptime
