Shafting
Joyce shafting matches perfectly with Joyce jacks and couplings to meet a wide variety of system requirements. Shafting is made from cold-finished 1018 steel, the ends machined to ANSI-standard keyways.
Diameter Selection Chart:
To use this chart, follow these steps:
- Find a “Shaft Torque” value in the far left column that is greater than, or equal to , you calculated torque value.
- Move to the second column to find your “Normal Shaft Diameter” (round up to arrive at an offered shaft size).
- The third column shows the maximum allowable shaft span before supports (pillow blocks) are required.
- Compare your actual shaft speed (RPM) with the maximum allowable speed ( RPM) for the shaft you have chosen. If you are above the allowable shaft speed, then increase the shaft size until it falls into the allowable range.
Length Specifying Information:
Joyce shafts can be ordered in 1/16 inch increments of length. When specifying shaft length, please refer to the table under Product Specifications below.
Ordering Information:
Shafting is an important component in jack and actuator systems and it is important to select the best option based on torque and rotational speed requirements. Contact Joyce/Dayton with your questions and, as a complimentary service, we will help you specify the compatible components for a complete system. Otherwise refer to the selection chart and example part numbers included here.
