Ariel can provide a fan drive shaft on the auxiliary end of the smaller compressor frames.  The fan drive shaft is to be used without a side load.  The shaft should be supported with an outboard bearing pillow block pair if used with a side loading similar to a belt drive load.  The fan drive shaft can be used up to the power limitations listed below.

The JGJ/2 shaft will require a pillow block arrangement for all applications to limit the axial thrust on the frame bearings.

The JG:A/2 and JGM:P:N:Q fan shafts connect to the crankshaft with a threaded connection.  To avoid the threaded fan shaft from backing out due to shutdown deceleration, the fan inertia must be limited.
