About the Airtac SCJ32 Standard Cylinder SCJ32X80-100S
The SCJ32X80-100S is a double-acting, single-rod AirTAC cylinder that puts stroke-end fine-tuning directly on the machine. With a 32 mm bore and an 80 mm nominal stroke, its rear adjusting screw provides a generous 100 mm of adjustment range, letting you dial in the exact stop position without swapping the cylinder or adding external hard stops. The built-in magnet (suffix -S) allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke sensing.
At 0.5 MPa, this model delivers 402 N of push force and 345 N of pull force, making it a capable actuator for light pressing, sorting, and diverting tasks. The 12 mm diameter piston rod and PT1/8 port thread keep the unit compact, while the 21 mm air cushion decelerates the piston smoothly at both ends. The body length A for this SCJ is 182 mm, and the standard operating pressure range is 0.15-1.0 MPa.
Airtac SCJ32 Standard Cylinder SCJ32X80-100S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X80-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 80 mm |
| Stroke adjustment | Up to 100 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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, 21 mm |
| Max stroke | Up to 1000 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCJ32 Standard Cylinder SCJ32X80-100S Is Used
Commissioning & Setup
The 100 mm adjustment range is ideal for commissioning new automated fixtures, allowing engineers to precisely dial in the stroke end position for grippers or stops without iterative disassembly.
Wear Compensation
In repetitive pressing or clamping operations, the adjustable screw can be turned to take up mechanical slack caused by pad wear, maintaining consistent contact force over the tooling's lifetime.
Diverting & Sorting
Use the SCJ32X80-100S on small part conveyors to create an adjustable-length pusher. The sensor-ready magnet confirms retraction, ensuring the pusher is clear before the next product arrives.
Is the Airtac SCJ32 Standard Cylinder SCJ32X80-100S the Right Cylinder?
Step up to the SCJ40 bore if your application requires more force; the 40 mm bore provides 628 N of push force at 0.5 MPa. For a fixed, non-adjustable stroke, the standard SC series is a simpler and more cost-effective alternative. If the load needs external guidance to manage side forces, consider pairing this cylinder with a linear guide or switching to a guided cylinder.
This SCJ32X80-100S is a direct replacement for any AirTAC SCJ adjustable-stroke cylinder of the same 32 mm bore, 80 mm nominal stroke, and 100 mm adjustment range, with a PT port, basic mounting, and a magnet. Ensure the replacement unit matches these exact specifications for a seamless swap.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ32 Standard Cylinder SCJ32X80-100S FAQ
A screw mechanism in the rear cap lets you shorten the stroke end position by up to 100 mm from the 80 mm nominal maximum. It adjusts the retracted end-stop only and does not change the cylinder's push or pull force.
At the standard 0.5 MPa operating pressure, the push force is 402 N and the pull force is 345 N. The maximum theoretical push force at 1.0 MPa is 82 kgf. Pull force is lower due to the area of the 12 mm piston rod.
