DFL Bearings are manufactured as a complete unit comprising housing, shaft with key, end disc and ball bearings. The grease filling of the sealed bearings is suitable for a lifetime operation. The offered units are assembled like the flanged DFL units. In addition, a slotted clamping flange allows fine adjustment of the fan impeller axial location. For more severe operating conditions, DFL Bearings can be customized with a re-lubrication feature and heavier duty bearings. Clients can avail these bearings from us in different specifications.
