NOTE: Avoid the temptation to "spin" the bearing when it is dry. This is the best way to destroy a new bearing...!!


When I was working with the MOD reconditioning helicopter gearboxes, one of the parts cleaning bods thoroughly enjoyed "spin" drying the bearings with compressed air and listening to them whine like a gas turbine on start-up!!

Needless to say the practice was stopped when someone sussed what the noise was and many expensive bearings saw ended up in the scrap bin.
