Order bearings for your alternators directly from the original alternator manufacturer to ensure as-new quality of spare part. For critical applications, we recommend that all users keep a set of DE and NDE bearings to avoid activity interruption in case of issue.
As alternator manufacturer, we keep track of all spare parts needed for Leroy-Somer generators, and we can provide all bearing parts types: ball bearings, sleeve bearings, lubrication systems, sensors etc… We also provide complete bearing installation kits.
Our list of available bearings includes:
We provide Drive End (DE) and Non-Drive End (NDE) bearings for LSA 62, LSA 60, LSA 58, LSA 58, LSA 56, LSA 54, LSA 53, LSA 52 and LSA 51 alternators amongst others.
Bearing failures can lead to extensive damage to the whole equipment which is why specific types of bearings have been selected and tested by Leroy-Somer to ensure the highest possible lifetime for the alternator.
Bearings with exactly the same reference or part number may be found at third parties, and notably online. However, even with the highest quality and from renown brands, they may ultimately have differences in design, tolerances, centricity or material.
Selecting the wrong bearing will likely lead to a different behaviour in operation and in early failure.
Do not leave the continued operation of your generator set to chance!
International studies report that more than 80% of the anti-friction bearing installed worldwide for any duty are prematurely damaged because of bad lubrication. To preserve your machine, we recommend to closely follow the recommendations contained in our manuals. Bearings must be lubricated regularly with the same type of grease as used in the factory.
In doubt, please ask us.
