About the Airtac SCJ32 Standard Cylinder SCJ32X155-10S
The SCJ32X155-10S is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw that provides up to 10 mm of field-adjustable stroke-end reduction. With a 32 mm bore and a 12 mm rod, it delivers 402 N of push force at 0.5 MPa, making it a compact yet capable actuator for fine-tuning end positions during commissioning or format changes.
This model includes a built-in magnet (-S suffix), allowing direct mounting of CMSG/DMSG/EMSG sensors on the tie-rod barrel for reliable, non-contact position feedback. The PT1/8 port and M10x1.25 rod thread ensure straightforward pneumatic and mechanical integration, while the 21 mm air cushion decelerates the piston quietly at the stroke end.
Airtac SCJ32 Standard Cylinder SCJ32X155-10S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X155-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 155 mm |
| Stroke adjustment | Up to 10 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 SCJ32X155-10S Is Used
Commissioning & Setup
Allows technicians to fine-tune the actuator's end stop by up to 10 mm on a new machine without modifying brackets or adding external hard stops, speeding up initial deployment.
Wear Compensation
In clamping or pressing fixtures, the adjustable stroke can be periodically tweaked to compensate for tooling wear or material thickness variations, maintaining consistent contact force.
Small Part Sorting
Useful on diverter gates or stops for small products where the stroke end needs a slight adjustment to handle a new batch, controlled by the 10 mm screw range.
Is the Airtac SCJ32 Standard Cylinder SCJ32X155-10S the Right Cylinder?
Choose the SCJ32X155-10S when you need to dial in a precise stroke end on a 32 mm bore platform without swapping cylinders. If more force is required, stepping up to the 40 mm bore provides 628 N of push at 0.5 MPa. For applications where the stroke must remain absolutely fixed after setup, a standard SC fixed-stroke cylinder is a simpler alternative. This adjustable-stroke unit is a direct replacement for another AirTAC SCJ32 cylinder with a 155 mm nominal stroke, 10 mm adjust range, PT thread, and a magnet, using basic mounting.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ32X155-10S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N due to the 12 mm rod area. The maximum push force at the 0.9 MPa operating limit is 724 N.
A screw in the rear cap limits the piston's retraction, shortening the effective stroke by up to 10 mm from the 155 mm nominal maximum. It does not adjust speed or force, only the stroke end position.
