The AirTAC Airtac SCJ63 Standard Cylinder SCJ63X160-30 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 30 mm range without swapping the cylinder. Ø63mm bore, 160mm nominal stroke, PT1/4 ports and adjustable end cushioning.
The SCJ63X160-30 provides a 63 mm bore with a nominal 160 mm stroke and a 30 mm rear-end adjustment range, letting you dial in the exact stroke end position during commissioning or format changes. Its 20 mm piston rod and PT1/4 ports deliver 1559 N of push force at 0.5 MPa, scaling to 2805 N at the 0.9 MPa maximum operating pressure.
This double-acting, single-rod cylinder uses a tie-rod construction with a 28 mm air cushion and a body length A of 197 mm. The rear adjusting screw shortens the stroke end by up to 30 mm without altering the cylinder’s rated force or bore, making it a practical choice for applications where the mechanical stop position needs field tuning.

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 30 mm rear adjustment screw lets technicians fine-tune the stroke end position during initial machine setup without removing the cylinder or machining external stops, speeding up line commissioning.
On packaging or assembly lines that switch between product sizes, the adjustable stroke allows operators to quickly reset the pusher or stop position by up to 30 mm, reducing changeover downtime.
In clamping or pressing fixtures where tooling or pads wear over time, the stroke-end screw can be advanced to take up the resulting gap, maintaining consistent contact without replacing the cylinder.
Choose the SCJ63X160-30 when you need a 63 mm bore push force of 1559 N at 0.5 MPa and the ability to trim the stroke end by up to 30 mm. If your force requirement drops, the 50 mm bore SCJ50 delivers 982 N push at the same pressure; if you need more, the 80 mm bore SCJ80 steps up to 2513 N. For a fixed-stroke application where no field adjustment is needed, the standard SC63X160 is a simpler alternative.
For direct replacement, match an AirTAC SCJ63 cylinder with a 160 mm nominal stroke, a 30 mm adjustment range, PT1/4 ports, and the same basic mounting configuration. At this 160 mm stroke, rod deflection is minimal, but if your load applies a significant side force, consider adding an external linear guide or switching to a guided cylinder to protect the rod bearing and seal.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N (reduced by the 20 mm rod area). At the maximum operating pressure of 0.9 MPa, the push force reaches 2805 N. The theoretical force at 1.0 MPa is 318 kgf, though the rated operating range is 0.15–1.0 MPa.
A rear-cap adjusting screw shortens the stroke end by up to 30 mm from the nominal 160 mm maximum. Pick the SCJ when you need to fine-tune the stop position on the machine—for commissioning, format changes, or wear take-up—without swapping cylinders. If your stroke is fixed and never needs field adjustment, the standard SC63X160 is a simpler, cost-effective alternative.
