Asymmetrical Torque Capacity

Asymmetrical loading occurs when the load is applied to one side of the unit. HBBY Series units can resist torsional loads that
are asymmetrical. The graphs on this page show torsional load capacity for standard shafting. For static values, multiply the
information in the graph by 1.5.

NOTE: Actuator life may vary depending on the severity of the following variables:
• Acceleration • Vibration
• Velocity • Orientation
