The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X80-100S 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. Ø80mm bore, 80mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X80-100S delivers substantial force in a field-adjustable package, generating 2513 N of push and 2268 N of pull at a standard 0.5 MPa supply. Its defining feature is a generous 100 mm rear-cap adjustment range, allowing operators to dial in the exact stroke end position for commissioning or format changes without replacing the cylinder.
This single-rod, double-acting unit uses a 25 mm diameter rod and PT3/8 ports, with a body length of 239 mm. The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG sensors for reliable, non-contact end-of-stroke detection. The adjustable cushion decelerates the piston smoothly, making it a robust choice for material handling and assembly tasks.

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.

The 100 mm adjustment range is ideal for fine-tuning the stroke of a diverter gate to perfectly align with different product widths on a packaging line, eliminating jams and misfeeds.
In automated welding or assembly fixtures, the adjustable stroke allows operators to quickly compensate for part-to-part variation or tooling wear, maintaining consistent clamp force without mechanical shims.
Use the rear adjusting screw to precisely set the final insertion depth for a press-fit operation, ensuring consistent assembly quality when changing between component batches.
Choose the SCJ80X80-100S when you need the 80 mm bore's force class but require extensive stroke-end adjustability. If your load demands less force, stepping down to the 63 mm bore provides 1559 N of push at 0.5 MPa, while stepping up to the 100 mm bore offers a significant jump to 3927 N. For applications that do not require stroke adjustment, a fixed-stroke SC80X80 cylinder is a simpler alternative. This model is a direct replacement for another AirTAC SCJ80 cylinder with an 80 mm nominal stroke, 100 mm adjust range, PT ports, and a magnet, using basic mounting.
Adjustable-stroke checklist
At the standard operating pressure of 0.5 MPa, this cylinder provides 2513 N of pushing force and 2268 N of pulling force. The maximum force at 0.9 MPa is 4523 N push. The pull force is lower due to the area taken up by the 25 mm piston rod.
The rear cap houses an adjusting screw that acts as an internal, variable end-stop for the piston. By turning this screw, you can shorten the effective stroke by up to 100 mm from its nominal 80 mm maximum, allowing for precise field setup without needing external hard stops.
