Availability : Sizes from 1 7/16” to 2 15/16” for all vertical shaft cooling tower applications.

Maintenance Tip: If replacing only the top fan shaft bearing on vertical shafts, the locking collar on the bottom fan shaft bearing must be loosened and then retightened after the installation of the new top bearing. This is critical because, by design, the top bearing is intended to handle the thrust load.
