About the Airtac JCK High Strength Welding Clamping Cylinder JCK40X90K
This JCK40X90K order code leaves the clamp arm field blank, so you receive the 40 mm bore power clamp body with a 90 degree opening and fit your own arm to match the fixture. The K option adds the PNP electrical position sensor (10-30 V DC, 2 mm sensing distance) and the ports stay PT1/8 because the G thread option is not selected. The double-acting toggle-link mechanism keeps the clamped position even if air supply fails.
Torque output is 120 Nm at 0.5 MPa with a maximum holding torque of 380 Nm, air is filtered to 40 um, and the air cushion plus 1 s minimum clamp and open times fit paced fixture cycles. Operating range is 0.3 - 0.8 MPa (43 - 116 psi) with proof pressure of 1.2 MPa (175 psi) and a temperature window of -20 to +70 C.

How to choose
Choose JCK40X90K when your PLC or sensor input expects a PNP high signal and you want the arm engineered in-house. If you prefer a ready arm, step up to JCK40X90AM1RK (15 mm offset) or JCK40X90AM3RK (45 mm offset) with R, C or L hole layouts. If wiring runs are difficult, the pneumatic-sensor JCK40X90KA replaces the electrical PNP option at the same 90 degree opening.
Applications
Custom-machined clamp arms
With no arm supplied, fixture builders bolt on an arm shaped to the part, then rely on the 380 Nm maximum holding torque to keep it locked through weld distortion.
PLC-verified clamping stations
The PNP sensor gives a sourcing 10-30 V DC signal with 2 mm sensing distance, letting the controller gate the next station on confirmed clamp position.
Compact multi-clamp manifolds
PT1/8 ports and a 40 mm bore with four-face DIN-standard mounting make it straightforward to bank several 90 degree clamps along a fixture rail.
FAQ
What figures define the JCK40X90K?
Bore 40 mm, opening angle 90 degrees, no clamp arm supplied, PNP electrical sensor (10-30 V DC, 2 mm sensing distance), ports PT1/8, output torque 120 Nm at 0.5 MPa, maximum holding torque 380 Nm, operating pressure 0.3 - 0.8 MPa (43 - 116 psi), proof pressure 1.2 MPa (175 psi), temperature -20 to +70 C, air filtered to 40 um, air cushion, 1 s minimum clamp and open time.
What must I check before fitting my own arm?
Confirm the arm against the load-torque limit of the series: 2.2 Nm at a 1 s cycle or 3.3 Nm at a 2 s cycle, and confirm the interface dimensions from the datasheet. The opening angle can later be changed by replacing the adjusting screw.
