About the Airtac JCK High Strength Welding Clamping Cylinder JCK40X45K
The JCK40X45K is the 45 degree opening version of the AirTAC JCK40 power clamp, a double-acting 40 mm bore cylinder built for welding and assembly fixtures. Its toggle-link mechanism keeps the clamp position even if air is lost, and the cylinder delivers 120 Nm of output torque at 0.5 MPa with a maximum holding torque of 380 Nm. Ports are PT1/8, the operating pressure range is 0.3 to 0.8 MPa (43 to 116 psi) and the temperature range is -20 to +70 C.
This code is supplied with no clamp arm, so you fit an arm matched to your fixture, and it carries the K sensor option: a PNP electrical position sensor that reports clamp state back to the controller. Opening angle is set in the order code and can be changed later by replacing the adjusting screw; the body mounts on four faces with DIN-standard mounting dimensions.

How to choose
Choose JCK40X45K over JCK40X30K or JCK40X60K when a 45 degree swing gives the right loading clearance for your part. Among sensor variants, pick K (PNP) if your PLC inputs expect a sourcing signal; KN (NPN) suits sinking inputs and KA (pneumatic) suits air-signalled fixtures. If you want a factory arm, order with AM1 or AM3 in an R, C or L hole layout instead of this no-arm code, and add G at the end for G threads instead of PT.
Applications
Welding fixture clamping
Double-acting clamp with 380 Nm maximum holding torque and a toggle-link lock that holds position through air loss, ideal for weld stations where the fixture must not relax mid-cycle.
PLC-monitored assembly fixtures
The PNP sensor gives electrical clamp confirmation, so a controller can verify the 45 degree closed position before the station is allowed to advance.
Custom-arm machining fixtures
Supplied without a clamp arm, letting you bolt on your own arm; keep arm loading within 2.2 Nm at a 1 s cycle or 3.3 Nm at a 2 s cycle.
FAQ
What are the key figures of the JCK40X45K?
Bore 40 mm, opening angle 45 degrees, PT1/8 port, operating pressure 0.3 to 0.8 MPa (43 to 116 psi), proof pressure 1.2 MPa (175 psi), output torque 120 Nm at 0.5 MPa, clamping torque 72/120/191 Nm at 0.3/0.5/0.8 MPa, maximum holding torque 380 Nm, temperature -20 to +70 C, air cushion, minimum clamp and open time 1 s each, weight 2.2 kg at 135 degrees with a 15 mm arm.
Do I have to buy a clamp arm for this code?
No. JCK40X45K is ordered with the arm option left blank, so it ships without a clamp arm and you fit your own. If you prefer an AirTAC arm, the ordering code accepts AM1 or AM3 (15 or 45 mm offset) with an R, C or L hole layout, horizontal or V for vertical mounting.
