The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X150-100SH is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 100 mm range without swapping the cylinder. Ø63mm bore, 150mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X150-100SH is a double-acting, single-rod AirTAC cylinder with a 100 mm field-adjustable stroke end, allowing precise fine-tuning without swapping hardware. Its 63 mm bore delivers 1559 N of push force at 0.5 MPa, making it a strong choice for commissioning trials and format changeovers on medium-duty automation.
This model is built with a 20 mm diameter piston rod, PT1/4 ports, and an M16x1.5 rod thread for standard end attachments. The suffix 'SH' specifies a built-in magnet for sensor mounting and high-temperature Viton seals, extending the operating range to 0–150 °C. The adjustable screw shortens the nominal 150 mm stroke by up to 100 mm from the rear cap.

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.

Related types: SC (single rod, fixed stroke), SCD (double rod), SCT (multi-position). SCJ mounting: Basic, FA, LB, TC, TCM1. Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Fine-tune the end position on a new assembly line by up to 100 mm without re-machining mounts, speeding up initial system integration and debugging.
Quickly adjust the stroke end for different product sizes on a packaging machine, reducing downtime between batches with a simple screw adjustment.
In hot environments up to 150 °C, use the rear screw to compensate for mechanical wear on a pressing or clamping station, maintaining consistent end force.
Step up to an 80 mm bore (2513 N push at 0.5 MPa) if your load exceeds the 63 mm bore's 1559 N capacity, or down to a 50 mm bore (982 N) for a more compact, energy-efficient solution. For applications needing a fixed, non-adjustable stroke, the standard SC series is a more economical alternative. A direct replacement must match the 63 mm bore, 150 mm nominal stroke, 100 mm adjustable range, PT ports, and Viton seals with a magnet. For this 150 mm stroke, if the rod experiences significant side loads, consider adding an external linear guide or switching to a guided cylinder to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
At 0.5 MPa, the cylinder provides 1559 N of push force and 1402 N of pull force. The maximum push force at the 0.9 MPa operating limit is 2805 N. The 100 mm adjustable stroke feature does not change these force values.
Yes, if you need the 100 mm field-adjustability. The SCJ63X150-100SH has the same 63 mm bore, 20 mm rod, and PT1/4 ports as a fixed SC63. However, the SCJ body is slightly longer to house the adjusting screw, so ensure you have the clearance for its 197 mm base body length.
