The chuck incorporates a hydraulic/pneumatic rotary cylinder, eliminating the need for cylinder 

installation. Its center through-hole design allows for operation with automatic feeding systems. 

Suitable for retrofitting traditional lathes into automated/semi-automated equipment, and for 

assembling various specialized machining tools. 

JA7-44/JH7-44 features a 2.0 times force-enhancing design, providing increased clamping force.

Cutting fluid should not be directly sprayed onto the chuck. An optional internal tensioning kit 

is available for the JA7-44/JH7-44 for internal tensioning clamping operations.
