Pivoting T-Arms
Clamping two workpieces with one cylinder
Collet-Lok® product line
Shown: CAC-202, CAPT-202; CAC-352, CAPT-352
for double-acting swing clamps
…quick and precise clamp arm positioning • Easy and precise location of the clamp arm in any position
Swing clamps
• Arm can be easily installed and fastened while the cylinder is mounted in the fixture to allow exact arm positioning • Vise not required for fastening arms or threaded into the fixture
01_001_1
• CAC-92, -202 and -352 are only to be used on double-acting cylinders
Clamp arms are used to transmit the force generated by the swing cylinder to the workpiece. The T-arm clamps two workpieces simultaneously with one swing cylinder. Enerpac recommends using the pivoting T-arms with doubleacting swing clamps of the SU, SL, ST and SC-series.
Allowable flow vs arm length
Important
The distribution of the clamp arm force is based upon the length of the T-arm as measured from the pivoting point.

When designing custom clamp arms, the flow rates must be further reduced. This rating should be in proportion to the mass and the center of gravity of the clamp arm.
Yellow pages
Installation dimensions in inches [
Example: If the mass of the arm is twice that of the long arm, flow rates must be reduced by 50%.
