The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X100-10S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 10 mm range without swapping the cylinder. Ø63mm bore, 100mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X100-10S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end. Its rear-cap adjusting screw provides up to 10 mm of fine-tuning on the stroke end position, letting you dial in the exact stopping point during commissioning or format changes without swapping the cylinder. The built-in magnet allows CMSG/DMSG/EMSG sensors to mount directly on the tie-rod barrel for reliable end-of-stroke detection.
This 63 mm bore unit delivers 1559 N of push force at 0.5 MPa and 2805 N at the maximum operating pressure of 0.9 MPa, with a 20 mm piston rod and M16x1.5 rod thread. The adjustable air cushion decelerates the piston smoothly over the final 28 mm of travel. With a body length of 197 mm, it is slightly longer than the fixed-stroke SC version to accommodate the adjusting mechanism, and it is rated for strokes up to 1500 mm.

Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max (@1.0 MPa) | 318 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

The 10 mm rear screw adjustment lets technicians fine-tune the stroke end position on a new assembly line without removing the cylinder, speeding up initial machine setup and debugging.
In clamping or pressing operations, the adjustable stroke can be extended slightly over time to compensate for tooling or pad wear, maintaining consistent clamping force without mechanical shims.
On packaging or labeling machines, operators can quickly adjust the cylinder's end stop to accommodate different product sizes, reducing changeover time between production runs.
Choose this 63 mm bore when the 50 mm bore's 982 N push at 0.5 MPa is insufficient, but a jump to the 80 mm bore's 2513 N is excessive for your load. The 10 mm adjustment range is ideal for fine end-stop tuning on fixtures that need only a small stroke correction. If your application does not require stroke adjustability, the fixed-stroke SC63X100 is a simpler, more compact alternative. For swinging loads, pair this with the TC centre trunnion mount (F-SC63TC).
This model is a direct replacement for another AirTAC SCJ63X100-10S with a PT port and built-in magnet. Ensure the replacement matches the bore, nominal stroke, and the 10 mm adjustment range. For strokes at or above 300 mm in this series, evaluate side-load forces and consider an external guide rail or a guided cylinder to prevent rod bending.
Adjustable-stroke checklist
At 0.5 MPa, it provides 1559 N pushing and 1402 N pulling. At the maximum operating pressure of 0.9 MPa, the push force increases to 2805 N. The push force is higher than the pull force because the single rod reduces the effective piston area on the return stroke.
You can, but the SCJ body is slightly longer to house the rear adjusting screw. It is a direct form-and-fit replacement only for another SCJ63 adjustable-stroke cylinder with the same nominal stroke, 10 mm adjustment range, PT port, and magnet option. The mounting footprint and rod dimensions are otherwise identical to the SC series.
