JSK torque at 0.5 MPa pressure timing ports and sensor specifications
Helpful for Model Matching:
| Identity / bore | Double-acting JSK power clamp cylinder, bore 40/50/63/80 mm. Bore 40 circular arm interface; 50/63/80 oval. Ordinary arm, position, sensor and port choices remain matching fields on this family page. |
| Output torque at 0.5 MPa | 40: 120 N·m; 50: 160 N·m; 63: 380 N·m; 80: 800 N·m, all at 0.5 MPa. This is torque, not arm-tip force or a universal load rating; actual force depends on geometry and applied pressure. |
| Pressure / air | Working 0.3–0.8 MPa; proof 1.2 MPa is not working pressure. Air filtered through a 40 μm element. |
| Temperature / cycle / cushion | −20 to +70°C. Minimum 1 second clamping and 1 second opening, not one second for the complete cycle. Air buffer cushioning. |
| Ports / thread | 40: 1/8; 50/63/80: 1/4. Ordering table publishes G thread only. Blank or B selects the illustrated port layout; compare the installation drawing; PT/NPT options are not listed. |
| Position / arm | Blank horizontal, V vertical. Arm blank: no clamping arm. 40: AM1 or AM3; 50/63/80: AM1/AM2/AM3/AM4. Each supplied arm needs R/C/L orientation per illustrated ordering diagram. |
| Offset / maximum opening angle | 40 AM1: offset 15 mm, max 135° horizontal / 120° vertical; AM3: offset 45 mm, max 105° both positions. 50/63 AM1/AM2: offset 15 mm; AM3/AM4: 45 mm; max 135° horizontal / 105° vertical. Bore 80 AM1/AM2 exception: offset 20 mm and 90° opening per ordering Note2, conflicting with the generic angle table/drawing; use a conservative 90° screen and confirm the exact supplied arm. 80 AM3/AM4: offset 45 mm, max 135° horizontal / 105° vertical. No-arm angle requires chosen-arm confirmation; published general opening range starts at 5°. |
| Sensor | Electrical inductive approaching position sensor. Blank none; K PNP; KN NPN. K/KN may be ordered separately. No S magnet suffix, reed-switch assumption or unverified wiring/power rating. |
| Mass | 40/50/63/80: 2.0/3.7/5.0/11.5 kg. Catalogue Note1 includes a 15 mm offset arm; bore 80 AM1/AM2 offset-20 exception means do not use this figure as a precise shipping weight for every code. |
| Installation / adjustment | Use bore/arm/position-specific drawings for mounting and port layout. Adjust arm to maximum opening, remove plug with H6 (40) or H8 (50/63/80), then adjust desired angle with the same hex-wrench size. Fixed inductive block moves with piston rod; no further sensor adjustment is specified after changing angle. |
| Materials / fit | Retain exact drawings and materials source. Material list is based on a certain bore, so exact-bore material confirmation is required. Drawings state pin-hole position tolerance ±0.02 and threaded-hole position tolerance ±0.1 mm. No self-locking or air-loss holding capability is established by this JSK catalogue. |

②Arm / direction
Blank no arm; 40 AM1/AM3; 50–80 AM1/AM2/AM3/AM4; supplied arm R/C/L. Bore 80 AM1/AM2: offset 20 mm, opening 90°.

Power clamp cylinders with 40/50/63/80 mm bores. Confirm horizontal or vertical position, arm geometry, inductive PNP/NPN sensing and G-thread port layout; send the installed model, quantity and destination for a quotation.
Ordering Note2 explicitly specifies 20 mm offset and 90° opening for bore 80 AM1/AM2. This exception conflicts with the generic table and grouped AM1(2) drawing (135° horizontal / 105° vertical). The lookup uses a conservative 90° screen; confirm the actual supplied arm and angle. Confirm the exact arm and installed opening before replacement.
The stated torque is measured at 0.5 MPa. Arm-tip force depends on effective lever geometry and application pressure. Send your fixture drawing and force requirement for confirmation.
The JSK catalogue does not establish that behavior. Send the required holding condition for technical confirmation; do not transfer claims from another clamp series.
