About the Airtac SCJ32 Standard Cylinder SCJ32X40-10S
The SCJ32X40-10S is a compact tie-rod cylinder that puts field-adjustable stroke control into a 32 mm bore package. Its rear-cap adjusting screw lets you shorten the stroke end by up to 10 mm without removing the cylinder—ideal for commissioning fine-tuning or taking up wear on small automation cells. With a 12 mm piston rod, M10x1.25 rod thread, and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa and 724 N at the maximum operating pressure of 0.9 MPa.
This model carries the -S suffix, so a built-in magnet is fitted directly into the piston. That means you can clamp CMSG, DMSG, or EMSG reed and solid-state sensors straight onto the tie-rod barrel for reliable end-of-stroke detection—no extra brackets needed. The body length A(SCJ) is 182 mm, and the double-acting single-rod design provides a genuine 21 mm air cushion at each end for smooth deceleration.
Airtac SCJ32 Standard Cylinder SCJ32X40-10S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X40-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 40 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 SCJ32X40-10S Is Used
Commissioning Fine-Tuning
Dial in the exact stroke end position during machine setup with the 10 mm adjusting screw, avoiding the need to shim or reposition the cylinder body on small pick-and-place modules.
Wear Take-Up on Clamp Units
Compensate for jaw or pad wear over time by advancing the stroke end slightly, maintaining consistent clamping force without replacing the actuator or adding external stops.
Small Part Ejection Gates
Adjust the gate opening stroke on a diverting conveyor to handle different product heights, using the SCJ32's 402 N push force to reliably move lightweight packages.
Is the Airtac SCJ32 Standard Cylinder SCJ32X40-10S the Right Cylinder?
Choose the SCJ32 when your application needs a small-bore cylinder with on-machine stroke tweaking. If you need more force, step up to the 40 mm bore SCJ40 series, which delivers 628 N push at 0.5 MPa. For jobs where the stroke is fixed and you want the simplest possible cylinder, the standard SC32 fixed-stroke model is a lighter, lower-cost alternative. When replacing an existing unit, match the SCJ32 bore, 40 mm nominal stroke, 10 mm adjust range, PT thread, and the -S magnet option; the basic mounting style uses the cylinder body directly. For strokes of 40 mm, side-loading is rarely a concern, but always centre the load on the rod axis.
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 SCJ32X40-10S FAQ
At the standard 0.5 MPa operating pressure, it generates 402 N of push force and 345 N of pull force. At the maximum 0.9 MPa pressure, push force increases to 724 N. The pull force is lower because the 12 mm piston rod reduces the effective piston area on the return stroke.
Yes, if you need the ability to fine-tune the stroke end. The SCJ32 shares the same bore, rod, port, and mounting footprint as the SC32 but adds a rear adjusting screw. Ensure the 10 mm adjustment range covers your stroke variation, and match the port thread (PT) and magnet option (-S) to your existing setup.
