Connecting shaft made from either turned, ground or polished steel.

Connecting Shafts

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.
  • (pages 136-137) and Block Supports (pages 140-141).

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.
