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.
