The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X100-10S 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, 100mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X100-10S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, providing a 10 mm fine-tuning range via a rear-cap screw. With an 80 mm bore and 25 mm rod, it delivers 2513 N of push force at 0.5 MPa, making it a robust choice for applications needing a 513 kgf class actuator with precise end-position control.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG/DMSG/EMSG sensors along the tie-rod barrel for reliable, non-contact position feedback. The adjustable stroke feature is ideal for commissioning and format changes, letting technicians dial in the exact stroke end without swapping the cylinder or adding external hard stops.

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.

Technicians can fine-tune the cylinder's end position by up to 10 mm during machine setup, compensating for small variations in tooling or workpiece placement without mechanical rework.
In high-cycle material handling, the adjustable screw can be turned in slightly to take up wear on a mating stop or gripper pad, maintaining precise positioning over the cylinder's service life.
For packaging or assembly lines running multiple product sizes, the 10 mm adjustment range allows a quick, tool-free stroke change between batches, reducing downtime compared to swapping fixed-stroke cylinders.
Choose the SCJ80X100-10S when you need a 100 mm nominal stroke with the ability to shorten the end position by up to 10 mm on the machine. If more force is required, stepping up to the 100 mm bore provides 3927 N of push force at the same pressure. For applications where the stroke is fixed and never needs adjustment, the standard SC80X100 is a simpler, more cost-effective alternative. This SCJ cylinder is a direct dimensional replacement only for another AirTAC SCJ80 with the same nominal stroke, 10 mm adjust range, PT ports, and built-in magnet.
Adjustable-stroke checklist
At the standard operating pressure of 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. The maximum push force at 0.9 MPa is 4523 N. Because it is a single-rod cylinder, the push force is always greater than the pull force due to the rod area.
A screw in the rear cap limits the piston's retraction stroke end by up to 10 mm, effectively shortening the stroke. This is a mechanical end-stop adjustment, not a locking device. The cylinder will not hold its position if air pressure is lost; an external rod brake or pilot-operated check valve is required for load holding.
