The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X80-30TC 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. Ø80mm bore, 80mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X80-30TC is a double-acting, single-rod pneumatic cylinder that lets you fine-tune the stroke end position by up to 30 mm using a rear-cap adjusting screw. With an 80 mm bore, it delivers 2513 N of push force at 0.5 MPa, making it a strong choice for mid-range automation tasks where the final stop point needs to be dialled in during commissioning or changeovers.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket, which allows the cylinder to pivot and is ideal for swinging or articulating loads. The 25 mm diameter piston rod and 28 mm air cushion provide robust, decelerated end-of-stroke performance. The body length A for this SCJ series is 239 mm, providing a compact footprint for its force class.

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.

Quickly adjust the end stop for different product sizes on a packaging line without mechanical rework, reducing downtime between batches.
Dial in the precise clamping stroke for parts with slight dimensional variations, ensuring consistent holding force without over-travel.
Fine-tune the actuator's stroke on a new assembly machine to perfectly synchronize with other tooling, simplifying the initial setup process.
Choose the SCJ80X80-30TC when your application requires a pivoting mount and the ability to adjust the stroke end by up to 30 mm without replacing the cylinder. If you need more force, stepping up to the 100 mm bore provides 3927 N of push force at 0.5 MPa. For a fixed, non-adjustable stroke, the standard SC80X80 cylinder is a simpler alternative. A direct replacement must match the 80 mm bore, 80 mm nominal stroke, 30 mm adjust range, PT port thread, and the TC centre trunnion mounting with its F-SC80TC bracket.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, it provides 2513 N of push force and 2268 N of pull force. The maximum push force at 0.9 MPa is 4523 N. The force is identical to a fixed-stroke SC80 cylinder.
A screw in the rear cap acts as an internal, adjustable end stop for the piston. Turning the screw changes the retracted stroke end position by up to 30 mm, allowing you to shorten the 80 mm nominal stroke without affecting the cylinder's force or speed.
