About the Airtac SCJ80 Standard Cylinder SCJ80X1000-30S
The AirTAC SCJ80X1000-30S is an 80 mm bore, double-acting, single-rod cylinder with a 1000 mm nominal stroke and a 30 mm field-adjustable range built into the rear cap. This model delivers 2513 N of push force at 0.5 MPa, operating on filtered air up to 1.0 MPa, making it a robust actuator for long-stroke applications where the exact end position must be dialed in during commissioning or changeover.
A built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for reliable end-of-stroke or mid-stroke position feedback. The 25 mm piston rod and PT3/8 ports handle high flow for the 1000 mm stroke, while the 28 mm air cushion at each end decelerates the piston smoothly, protecting the cylinder from impact damage.
Airtac SCJ80 Standard Cylinder SCJ80X1000-30S Technical Specifications
| Model | Airtac SCJ80 Standard Cylinder SCJ80X1000-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø80 mm |
| Nominal stroke | 1000 mm |
| Stroke adjustment | Up to 30 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 28 mm |
| Max stroke | Up to 1500 mm |
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.
Theoretical Output Force (Ø80mm)
| 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.

Where the Airtac SCJ80 Standard Cylinder SCJ80X1000-30S Is Used
Long-Stroke Part Transfer
The 1000 mm stroke moves components between distant conveyor stations. The 30 mm adjust screw lets technicians fine-tune the final stop position to perfectly align with the receiving nest, compensating for conveyor belt wear or product variations without reprogramming.
Automated Glue Dispensing
Powers a glue head across a 1-meter panel. The adjustable stroke end is critical for setting the precise shut-off point, preventing over-travel and ensuring a clean bead edge. The built-in magnet sensor confirms the head has fully retracted before the next cycle starts.
Format Changeover on Packaging Lines
Adjusts the stroke of a case packer ram for different box heights. Operators can quickly turn the rear screw to shorten the stroke from 1000 mm down to 970 mm for a new product size, eliminating the need to swap the cylinder or install hard stops, drastically reducing changeover time.
Is the Airtac SCJ80 Standard Cylinder SCJ80X1000-30S the Right Cylinder?
Step up to the SCJ100X1000-30S if your application requires more force; the 100 mm bore provides 3927 N push at 0.5 MPa, a significant jump from this 80 mm model's 2513 N. For lighter, more compact needs, the SCJ63X1000-30S offers 1559 N push. This SCJ80X1000-30S is the correct replacement for any AirTAC SCJ adjustable-stroke cylinder of the same 80 mm bore, 1000 mm nominal stroke, 30 mm adjust range, PT port thread, and S magnet option. For a 1000 mm stroke, always evaluate side-loading and rod buckling; an external guide rail or a switch to a guided cylinder is recommended if the load is not perfectly axial.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ80 Standard Cylinder SCJ80X1000-30S FAQ
At the standard 0.5 MPa operating pressure, this cylinder provides 2513 N of push force and 2268 N of pull force. The push force is higher because the single rod reduces the effective piston area on the pull side. At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
The -30 code means a rear-cap adjusting screw can shorten the stroke end by up to 30 mm from the 1000 mm nominal maximum. You choose an SCJ when you need to fine-tune the piston's stop position on the machine—for example, during initial setup, to take up mechanical wear, or to adapt to different product sizes. A fixed-stroke SC cylinder is the better choice if your end position is permanently fixed and never needs adjustment.
