Determining airshaft weights

The chart above lists the approximate weights of the more common types and sizes of standard duty Nim-Cor airshafts. Some notes to remember about Nim-Cor airshafts include:

Heavy or extra heavy-duty models of a given size would weigh more because of the heavier wall used for the shaft body.

The exact weight of any Nim-Cor airshaft can be computed if the exact dimensions and requirements are known.

The drawing below shows how to figure the handling weight of a typical button-type airshaft suitable for handling 3" I.D. cores on a 30" web face in all steel and with a steel or aluminum body.

EXAMPLES:

Alum. Body - Steel Journals
Body 0.45 x 36 =	16.20
Headers (2) =	7.00
Pin Journal 0.89 x 8 =	7.12
Valve Journal 0.89 x 4 =	3.56
Total =	33.88#

Steel Body - Steel Journals
Body 0.80 x 36 =	28.8
Headers (2) =	7.00
Pin Journal 0.89 x 8 =	7.12
Valve Journal 0.89 x 4 =	3.56
Total =	46.48#
