 Why Maintain Proper Bearing Lubrication?
Class 6 Clean Room with Class 5 Clean Benches, meeting ISO 14644-1

Proper lubricant can reduce friction, prevent bearing wear, protect bearing surfaces from corrosion, and carry away excess heat from bearing operation.  

Bearings operate on a very thin film of lubricant which must be maintained, or replaced, to ensure that maximum bearing life is achieved.  

Proper selection, application, and maintenance are vital in maximizing bearing life 

Maintaining your bearings with proper lubrication will reduce friction and wear.   

Can PKB Relube Bearings That Were Manufactured By Other Companies?Yes. PKB regularly performs re-lubrication services on bearings that were originally manufactured by many other companies.    

When Should Bearings be Relubed?

  • PKB recommends that bearings should be relubed within three (3) years of the original manufacturer's lube date, or if any of the following conditions occur:
ISO 9001:2008 - AS9100:2009  FAA TSO-C149 - ISO 14644-1
  • Bearings should be relubed at the recommendation of the bearing manufacturer
  • Bearings have been subjected to temperature or humidity conditions outside of the recommended temperature range
  • Bearings have become contaminated 
  • The original packaging has become damaged
  • If you're unsure of the lubricant's expiration date
  • There is any question about the quality, condition, or type of lubricant in the bearings
  • The bearing lubrication appears to have separated, discolored, or otherwise changed appearance 

Can't I Just Wash Out the Lubrication and Install New Lube?

Many 440C Stainless Steel Bearings that are used in Aerospace, Medical, and other applications can be cleaned and relubricated, in proper Clean Room conditions, and by trained personnel. Improper handling can result in cross contamination, problems with wettability on balls & bearing races, or ball & raceway damage, as well as broken, cracked, lost or otherwise unusable retainers, seals, shields, balls, or wires.  PKB provides bearing wash and relubrication services, for many Aerospace OEMs and authorized resellers, in our factory Clean Room.
