| Notes: 1. Pounds at zero deflection based on pure radial load. Performance of pivot is a function of number of cycles, angular travel, and loading. Must use life cycle curves for selection of proper pivot. When the load is applied directly through a single spring, multiply capacity by 0.707. 2. At zero load, Torsional Spring Rate may change with radial load. | |||||||
