The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X225-10S 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. Ø80mm bore, 225mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X225-10S is a double-acting, single-rod tie-rod cylinder that puts fine stroke-end tuning at your fingertips. With an 80 mm bore delivering 2513 N of push force at 0.5 MPa and a 10 mm rear adjusting screw, you can dial in the exact end position on the machine without swapping the cylinder or adding external hard stops.
This model includes a built-in magnet (-S suffix), so CMSG/DMSG/EMSG reed and solid-state sensors clamp directly onto the barrel for reliable end-of-stroke detection. The 25 mm piston rod and PT3/8 ports handle flow rates for speeds up to 800 mm/s, while the 28 mm air cushion decelerates the load smoothly at both ends.

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 | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 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.
During machine setup, the 10 mm rear screw lets technicians micro-adjust the stroke end position to perfectly align with mating tooling or fixtures, eliminating the need to machine custom spacers.
In high-cycle material handling, the adjustable stroke can be periodically tweaked to compensate for wear on external stops or gripper pads, maintaining consistent part placement without downtime for cylinder changes.
For packaging lines running multiple product sizes, the screw adjustment allows a single cylinder to be quickly reconfigured for different push or eject strokes, reducing changeover time and spare parts inventory.
Choose the SCJ80X225-10S when your application needs a 225 mm nominal stroke with up to 10 mm of field-adjustable retraction for commissioning or format changes. If 2513 N of push force at 0.5 MPa is slightly more than needed, the 63 mm bore SCJ delivers 1559 N; if you need more force, the 100 mm bore provides 3927 N at the same pressure. For applications where the stroke never needs adjustment, a fixed-stroke SC80X225-S cylinder is a simpler, cost-effective alternative.
This cylinder is a direct replacement for another AirTAC SCJ80X225-10S with PT ports, basic mounting, and a magnet. At 225 mm of stroke, ensure the rod is not subjected to high side loads; if lateral forces are present, add an external guide rail or consider a guided cylinder to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
At 0.5 MPa, the cylinder delivers 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The pull force is lower due to the area of the 25 mm piston rod.
Yes, if you need the 10 mm stroke-end adjustability. The SCJ80X225-10S shares the same mounting footprint and port sizes as the SC80, but the body length A(SCJ) is 239 mm, which is slightly longer than the fixed-stroke version to house the rear adjusting mechanism.
