About the AirTAC JCK50
The AirTAC JCK50 is a double-acting power clamp cylinder for welding and assembly fixtures, with a 50 mm bore and a toggle-link (crank slider) mechanism that holds the clamp position even if air is lost. It gives 160 N·m output torque at 0.5 MPa and holds up to 800 N·m. Ports are PT1/4; operating pressure 0.3 - 0.8 MPa (43 - 116 psi), proof pressure 1.2 MPa (175 psi), temperature -20 to +70 °C, air cushion, minimum clamp and open time 1 s each.
The opening angle is set in the code (15, 30, 45, 60, 75, 90, 105, 120, 135°) and can be changed later by replacing the adjusting screw. Clamp arms AM1 and AM3 (15 or 45 mm offset, AM2 and AM4 with larger holes) come in R, C and L hole layouts; position sensing is by PNP (K) or NPN (KN) electrical sensor or a pneumatic sensor (KA). The body mounts on four faces with DIN-standard mounting dimensions.

Where the JCK50 Is Used
Welding fixtures
Clamps sheet-metal parts on body-in-white and robot welding jigs.
Assembly lines
Holds parts in position during joining.
Monitored clamping
K/KN/KA sensors confirm open/closed.
Choosing the Right JCK50 Configuration
Start with the opening angle: 15, 30, 105, 120, 135° are listed; with an arm the maximum is 135° horizontal and 105° vertical.
Then the clamp arm: no arm (fit your own), or AM1-AM4 in R, C or L hole layout. V mounts the arm vertically. Check the arm against the load-torque limit: 4.5 N·m at a 1 s cycle, 6.7 N·m at 2 s.
Finally the sensor and thread: blank = no sensor, K = PNP, KN = NPN (10-30 V DC, 2 mm sensing distance), KA = pneumatic sensor. Ports are PT unless the code ends in G.
