The new range of Mahle Motorsport bearings contains technology that has been transferred from Mahle’s F1 bearing technology. All bearings in this range are identified by laser marking as opposed to stamping.
 
Benefits of Laser Marking:
 
The cheapest method of identifying a bearing is by stamping.
 
For motorsport applications where higher temperatures are experienced, the effectiveness of heat transfer into the housing should not be compromised.
 
If the stamping is heavy and extends quite far round the bearing causing poor back contact then the efficiency of heat transfer will be reduced.
 
Laser marking is an alternative method which creates smaller, more consistent marking which does not distort the backing and as such does not disrupt the back contact and subsequent heat transfer.
