Handwheels listed are recommended sizes to produce full rated torque with the rim effort listed. The formulas listed below will assist you in determining alternate handwheel sizes and rim pull requirements based on your application.
- To find handwheel diameter for given output torque at a given rim effort, divide the output torque by the mechanical advantage and multiply the result by 2. Then divide this result by the handwheel rim effort.
- To find rim effort for a given output torque with a given handwheel diameter, divide the output torque by the mechanical advantage and multiply the result by 2. Then divide this result by the handwheel diameter. Handwheels are not included as part of the operator part list or price.
Bores, keyways, and mounting patterns listed are for Cameron standard stocking units. Please contact Cameron for special bore treatments, costs, and deliveries.
