How to Match a Replacement Shaft to Your Fan
Loren Cook uses different shaft part numbers across its fan lines and sizes, so the shaft number has to match your unit. Two fans of the same style can take different shafts.
The fastest way to confirm is the model and serial number on the fan’s nameplate. If the tag is worn, the Loren Cook serial number lookup shows where to find it and what each part of the number means.
Genuine Loren Cook Shafts and Parts
A shaft is often replaced along with the bearings, pulleys, or fan blade on the same unit. We supply all of them by Cook part number, so the whole repair ships together.
As an authorized Loren Cook distributor, Heinlein can supply parts for units that are no longer in production, and can source a replacement part or a whole replacement fan. Call us with your serial number and we will list every part your fan needs.
