Problem Scenario – A common system operating problem stems from connecting shafts made from standard steel, which are often bowed or out-of-round.
This results in a whipping effect while the system is being run with the connecting shaft working its way loose from the system at high speeds and doing a great deal of damage to the system’s equipment.
Solution – Duff-Norton connecting shafts, which are furnished with close tolerance Turned, Ground, and Polished steel for smooth rotation.
Features
Turned, Ground, and Polished steel.
Shaft material is machined from cold-drawn bar.
Furnished with ANSI-standard in-line keyways.
Coordinates well with Duff-Norton Couplings.

Shaft Selection Criteria
Instructions:
Find a torque value that is greater than or equal to your calculated torque requirements.
Use the second column to find the required shaft diameter (rounding up is recommended.)
Check the third column for the maximum allowable shaft span before supports are required.
Match your selected shaft’s maximum allowable speed (rpm) to actual shaft speed (rpm). Increasing your selected shaft size is recommended until it falls into the allowable range.
