Torque Tubes
Knight’s Torque Tubes are designed to reduce operator fatigue by absorbing torque reaction produced by assembly tools while balancing the tool weight. Torque Tubes use a pneumatic cylinder or spring balancer to achieve zero gravity balancing. Each pneumatic cylinder is supplied with single balance control.
Torque Tubes are most commonly used as tool holders by incorporating Knight’s ASA9518 360 degree Rotating Tool Clamp or Knight’s ASA9500 and ASA9501 Adjustable Fixed Tool Clamps.

Light Torque Tubes
Torque Tubes are ideal for small hand tools, pneumatic nutrunners and torque tools. Torque tools have a maximum capacity of up to 70 lbs. [32kg], 150 ft-lb. [203nm] at 100 psi [6.8bar].
Medium and Heavy Torque Tubes
Torque Tubes are more commonly used for high torque producing tools and applications with custom designed tooling. Torque tools have a maximum capacity of up to 500 lbs. [227kg] and 853 ft-lb. [1,156nm] at 100 psi [6.8bar].
Cylinder torque tubes are ideal in conditions where there is a need for the tool to remain in the same position after fastening. In other words, it remains balanced at any position in the vertical travel. Torque Tube safety cables (#RWA4133) are sold separately.

Spring Balancer Torque Tubes (Light/Medium Duty)
Knight Spring Balancers Torque Tubes can be used in various applications due to air not being a requirement for operation. Spring Balancer Torque Tubes are available in a light and medium duty configuration with a maximum capacity of up to 35 lbs. [15.8kg] and 300 ft-lb. [406nm].
Spring Balancer torque tubes are ideal in conditions where there is a need for the tool to return to the full UP position after fastening. Torque Tube safety cables (#RWA4133) are sold separately.
