Hollow Piston Clamps

The clamp's piston, which is hollow,moves inside the body when hydraulic pressure is applied. Powerful springs open the clamp when the hydraulic pressure is shut off. The stud, which is attached to the T-nut, is screwed into the threaded hollow piston.

All of the hollow piston clamps shown below are available with a mechanical lock.

Hollow piston clamps must be supported on at least two 180 degree opposite sides. Therefore, they must be used with dies or molds having U-slotted underplates, pockets, ears or stud clearance holes.

Several clamp models are illustrated and described below.

Model 200  - Hydraulic Nut

10,000 lbs of clamping force @5000 psi.

Shown with mechanical lock and stud/T-nut.

 

Model 201 - Hydraulic Nut

201.tif (59675 bytes)

 

15,000 lbs of clamping force @5000 psi.

Shown with a one piece 1" forged stud/T-nut.

 

Model 203 - Hydraulic Nut (Mug Clamp)

203.tif (37976 bytes)

26,000 lbs of clamping force @5000 psi. Shown with mechanical lock.

Incorporates handle for easy movement in T-slots. 1" diameter stud standard. Built-in misalignment tolerance device accommodates up to 4 degrees of misalignment.

Model 205 - Miniature Hydraulic Nut

205.tif (58083 bytes)

8,000 lbs of clamping force @5000 psi.

Shown with mechanical lock.

The compact profile makes the clamp ideal for use in space constrained applications.

The stud may be connected to a T-nut.

 

Model 210 - Miniature Hydraulic Thumbscrew and

Model 225 - Hydraulic Thumbscrew

210.tif (65048 bytes)

The Model 210 and Model 225 generate 8000 and 10000 lbs of clamping force respectively @5000 psi.

Knurled thumbscrew on top of clamp allows rapid finger tight rotation of stud for quick engagement in a threaded hole.
