Helpful for Model Matching:
| Product identity | JCH is a double-acting dual telescopic-pin cylinder with two copper-bushing guide groups and a flat body. JCP single telescopic pin is a different family; no independent pin actuation, clamping force or safety-lock function is established by this source. |
| Published bore/stroke/pin types | 40 mm bore: 40 mm stroke, typeA.63 mm bore: 40/60 mm stroke, typeB. TypeA/B is tied to the published bore matrix, not a free choice on both bores.40×40 and 63×40/60 have distinct dimension references. |
| Source example conflict | The JCH ordering header shows JCH40X60AK, while the model matrix lists only a 40 mm stroke for bore 40 and the dimension drawing identifies JCH40X40. Confirm the 40×60 request against the original label and drawing. |
| Operating conditions | Operating pressure 0.3–0.8MPa; proof 1.2MPa not service pressure. Air filtered 40 μm or finer;−20 to 70°C. No maximum piston speed, load capacity or repeatability is published in this two-page sheet. |
| Sensor choices | Blank: no sensor; K: inductive proximity sensorPNP; KN: NPN. DIST-series sensing, not a reed-switch/magnetS ordering field. K/KN sensors may be purchased separately; confirm exact voltage, wiring, connector and quantity from actual sensor literature. |
| Pneumatic ports | 40 bore PT1/8; 63 bore PT1/4. Blank threadPT orG suffix forG thread. NoNPT/T published. Actual sensor interface and pipe thread are separate procurement fields. |
| Mounting and positioning | Three-face mounting is published. Match both pin-end interfaces, spacing, workpiece datum, mounting holes and clearance against the correct size drawing. Marked drawing pin-hole position tolerance±0.02 mm and screw-hole position±0.1 mm do not establish machine-level positioning repeatability. |
| Protection and construction | Source lists metal dust ring and scraper for two-stage weld-spatter protection, high-strength aluminum-alloy body and copper sliding bushings. An IP rating, seal immunity and unrestricted welding exposure are not specified. |
| Body weights | 40×40: 1.1 kg; 63×40: 4.5 kg; 63×60: 4.7 kg. The specification also lists 1.2 kg in the 40-bore 60-stroke weight row, which conflicts with the ordering/dimension matrix; do not use that row to validate 40×60 automatically. |
| RFQ inputs | Send fullJCH label, 40/63 bore and stroke, A/B pin type, sensorPNP/NPN or none, PT/G, both pin/mounting photos and workpiece drawing, quantity and destination. Confirm installed fit, load conditions and actual sensor/cable supply before replacement. |
