| Product function and direction | JQK clamps a base plate with a guide pin and pull mechanism. Double acting; normal pull is blank, reverse pull is R. The catalogue permits mounting on either side. Confirm actual plate/fixture drawing and force direction. |
| Bore versus guide-pin diameter | Bore 32 or 63 mm. Round guide pin: 17.1–17.9 / 19.1–19.9 / 24.1–24.9 / 29.1–29.9 mm for workpiece holes 18 / 20 / 25 / 30 mm. Code 249 means a 24.9 mm pin, not a 249 mm bore or stroke. |
| Platform and clamping thickness | Published platform height L45 = 45 mm; T16 = 1.6 mm clamping thickness. Thickness can be customized according to the source, but only T16 is tabulated here. Neither field is a cylinder stroke; other thickness or platform height requires confirmation. |
| Working pressure and proof pressure | Operating pressure 0.3–0.8 MPa, proof pressure 1.2 MPa separately. Air filtered to 40 μm or finer. Working temperature −20 to 70 °C. |
| Force values at 0.6 MPa | At 0.6 MPa, JQK32 clamping force 1800 N and maximum retention 2500 N; JQK63 clamping force 3300 N and maximum retention 3800 N. These are different published values, not interchangeable universal load ratings. |
| Self-locking and loss-of-air boundary | The source states an internal self-locking mechanism continues to provide clamping force after air loss. It does not publish a safety certification, dynamic braking rating or an unconditional permitted load under every fixture/control condition. Confirm actual load, fixture, release and air-loss sequence. |
| Opening and clamping time | Catalogue minimum opening/clamping time: 1 second to open and 1 second to clamp. A shorter cycle is not established by pin size or pressure range; confirm actual air circuit and sequencing. |
| Port and thread | JQK32 PT1/8; JQK63 PT1/4. Ordering blank = PT, G = G thread; source notes PT/G alternatives. No NPT/T suffix is listed in the catalogue. |
| Position sensor | DIS-series inductive proximity sensor. Blank = no sensor, K = PNP included, KN = NPN included. These are electric inductive sensors, not a magnet/reed-switch code. DIS sensor may be ordered separately; confirm wiring and supply scope against its own catalogue. |
| Fixture mounting and envelope | Own JQK32/JQK63 drawings show M8×1.25 mounting holes, 12 mm depth, and Ø8 locating holes, 10 mm depth, on both sides. Compare own body dimensions, locating-hole tolerances and sensor projection; matching bore/pin size alone does not confirm mounting interchangeability. |
