Ordering Details for This Model

This listing retains the original compact code without X. The catalog ordering diagram separates size and opening angle with X. It describes a complete JCK cylinder with factory-installed KA pneumatic sensing, not a separately sold sensor cartridge.

Model Code Explained

Parameter	Details
JCK	Power clamp cylinder
40	Cylinder size 40; round cylinder body
15	15° opening angle; this is an angle code, not a 15 mm cylinder stroke
KA	Factory-integrated pneumatic position sensing; catalog sizes 40, 50 and 63 only

Technical Specifications

Parameter	Details
Action	Double acting
Air supply	Compressed air filtered through a 40 µm element
Pressure	0.3–0.8 MPa
Proof pressure	1.2 MPa
Temperature	−10 to 60°C
Nominal output torque at 0.5 MPa	120 N·m
Minimum cycle movement	1 second to clamp; 1 second to open
Cushioning	Pneumatic cushion
Air ports	PT 1/8
Opening angle	15° in the retained model; final allowable angle also depends on the separately selected arm and its mounting position
Internal travel for selected angle	20.2 mm, from the catalog angle-to-stroke table
Handle	No manual handle code
Supplied arm	No arm specified; select an appropriate F-JCK arm separately
Position sensing	Pneumatic; factory-integrated, unavailable for size 80 in this catalog
Mounting faces	Three faces for factory pneumatic-sensing KA

Clamping Torque and Load Selection

Parameter	Details
Maximum clamping torque at 0.3 MPa	72 N·m
Maximum clamping torque at 0.4 MPa	95 N·m
Maximum clamping torque at 0.5 MPa	120 N·m
Maximum clamping torque at 0.6 MPa	143 N·m
Maximum clamping torque at 0.7 MPa	167 N·m
Maximum clamping torque at 0.8 MPa	191 N·m
Maximum holding torque	380 N·m
Permissible arm-load moment	2.2 N·m for 1-second clamp/open; 3.3 N·m for 2-second clamp/open
Interpretation	The specification table gives nominal 0.5 MPa torque; the separate selection table gives the pressure-dependent values shown here. Maximum clamp force occurs at the final locked position.
Force at the clamping point	Select from the catalog torque / arm-length and shim-thickness curves. A longer arm reduces force. Do not treat cylinder output torque as a guaranteed fixture tip force.
Datum-to-pivot offset A	12 mm

Current Model Dimensions

Parameter	Details
Body drawing overall reference	254.5 mm; illustrated assembly dimension, not a linear function of angle
Main housing width	54 mm
Bottom-body width	50 mm
Main mounting threads	4 × M6 × 1.0, depth 10
Axial mounting threads	2 × M6 × 1.0, depth 10
Locating-hole references	Ø6H7, depth 8
Arm shaft square	16 mm
Arm clamp bolts	M6 × 1.0; recommended tightening torque 13.8 N·m

Compatible Accessories and Sensors

Parameter	Details
Angle adjustment screw	F-JCK40X15LM; sets the corresponding internal travel. The fitted arm and manual configuration still limit permitted opening angle.
Compatible clamp-arm families	F-JCK40AM1R / F-JCK40AM1C / F-JCK40AM1L, F-JCK40AM3R / F-JCK40AM3C / F-JCK40AM3L
PNP / NPN sensor assembly	DS1KP63 / DS1KN63; 63 versions fit JCK40, JCK50 and JCK63
Sensor cables	X-F-PPVCS: straight 3 m cable; X-F-PPVCL: right-angle 3 m cable
Field-wireable connectors	X-F-PPVCV: straight female circular connector; X-F-PPVCH: right-angle female circular connector
Pneumatic sensing	KA is integrated at the factory and is not available as an independent sensor accessory; listed only for JCK40/50/63

Factory Pneumatic Sensing

Parameter	Details
P supply signal port	M5 × 0.8
A signal output	M5 × 0.8; clamped-position air signal
B signal output	M5 × 0.8; unclamped-position air signal
Operation	Built-in mechanical valve provides an air-pressure signal for an all-pneumatic control circuit
Assembly	Sealed sensing arrangement resists welding spatter; it is part of the cylinder assembly

Materials

Parameter	Details
Adjustment screw	Free-cutting steel
Covers, tube and cushion body	Aluminum alloy
Sensor mounting bracket	Plastic
Y link, reinforcing plate, connecting link and pivot shaft	Alloy steel
Return pin and piston rod	Medium-carbon steel
Clamping arm	Cast steel
Piston item, as listed in catalog	NBR

Operation and Adjustment

Use only the matching catalog-listed clamp arms. Select total arm mass and center-of-gravity offset from the load curves and use flow control for opening and clamping.
Adjust workpiece clearance with shims, then verify that the linkage passes the dead center and the return pin projects to show the locked state. Excessive shim thickness can prevent locking.
Fit side guides when necessary without imposing side load or obstructing the arm. With a hard stop, set stop clearance first and then adjust the workpiece pressure block.
To change opening angle, fit the matching F-JCK adjustment screw and reposition only the O (open) sensor to the angle mark. The C (clamped) sensor is factory set and must not be moved.
Except at the 15° setting, the O mark faces downward during sensor installation. Keep the sensor-to-Y-link clearance below 1.5 mm.
When fitting the arm, match the shaft indicator line to the catalog horizontal or vertical installation drawing. Tighten the contact-side V-block screw first and the open-side screw last, to the listed torque.
The linkage is mechanically self-locking at the clamped end. After isolating the air, the return pin can release the lock; keep clear of the arm because it may spring open.
A manual HL/HR version also allows manual clamping and release. Without HL/HR the model must not be described as supplied with a manual handle.

Weight and Source Notes

Parameter	Details
Reference weight	1527.1 g
Weight basis	Catalog assembly reference: 2200 g for 135° standard 40-size JCK with its 15 mm-offset arm. Estimated configuration correction subtracts 672.9 g AM1 fork envelope because this model has no arm code. The arm estimate uses the published fork dimensions and 7.85 g/cm³ nominal steel density; holes and contour details are not individually weighed. Sensor, angle-stop and handle variations are not independently tabulated. This is a configuration reference estimate, not a measured mass.
Technical source	AirTAC 2022 Chinese comprehensive catalog, execution printed pages 365–382; checked against the product PDF download above.
Actual supplied mass	Reference value only; actual weight is determined by the supplied product, not an individually weighed or packed shipping mass.
