Why order bearings from Leroy-Somer?

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 industrial 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!

Care for your bearings

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.
