Kurt’s new KHU6 hydraulic unit comes ready with both single- and double-acting capabilities providing a convenient option to the users preferred clamping method. Single-acting method uses hydraulic clamping and spring return for unclamping. Double-acting capability uses both hydraulics to clamp and unclamp for faster, more precise setup.
Switching between single and double acting only requires switching out the brass breather fitting with the supplied hydraulic fitting. The KHU6 is available as a retrofit for existing vises and will come standard on all Kurt 6 inch hydraulic vises for the HDH690, HDH691 and 3600H, 3610H, 3630H, XL6H and XL6HR models.
The KHU6 hydraulic unit uses 3,200-psi operating pressure which provides a 0.25” stroke and 7,200 pounds of clamping force. Clamping consistency and improved part quality are benefits of hydraulic vise actuation. Clamping speed is also significantly faster than manually closing and opening vise jaws and can save hundreds of hours over the course of a year for an easy pay-back.
The KHU6 hydraulic unit is a direct replacement for 36BHU hydraulic, which has been removed as replacement and as originally offered in many Kurt 6 inch vises.
