About the Airtac SCJ32 Standard Cylinder SCJ32X20-10S
The SCJ32X20-10S is a double-acting, single-rod pneumatic cylinder that puts fine stroke-end tuning directly on the machine. Its rear adjusting screw provides up to 10 mm of adjustment, letting you dial in the exact 20 mm nominal stroke without swapping the cylinder. The built-in magnet allows CMSG/DMSG sensors to clamp directly onto the 182 mm tie-rod body for reliable end-of-stroke sensing.
At 0.5 MPa, this 32 mm bore unit delivers 402 N of push force and 345 N on the pull stroke, with a 12 mm diameter piston rod. The PT1/8 port and M10x1.25 rod thread make it a compact, easy-to-plumb solution for light positioning tasks. The 21 mm air cushion protects the end cap during high-cycle operation.
Airtac SCJ32 Standard Cylinder SCJ32X20-10S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X20-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 20 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 SCJ32X20-10S Is Used
Commissioning Fine-Tuning
The 10 mm adjustment screw allows technicians to precisely set the stroke end during machine setup, compensating for small assembly tolerances without needing shims or external stops.
Small Part Stops
Ideal for actuating a retractable stop on a compact conveyor line. The adjustable stroke lets operators change the stop position for different product sizes on the fly.
Wear Compensation
In high-cycle clamping fixtures, the stroke can be easily adjusted over time to compensate for pad wear, maintaining consistent clamping force without replacing the cylinder.
Is the Airtac SCJ32 Standard Cylinder SCJ32X20-10S the Right Cylinder?
Choose the SCJ32X20-10S when you need to fine-tune a short stroke on a compact machine. If your force requirement grows, stepping up to the 40 mm bore provides 628 N of push force at the same 0.5 MPa. For applications where the stroke is fixed and never needs field adjustment, the standard SC32 series offers a simpler, cost-effective alternative. To replace this unit, match the 32 mm bore, 20 mm nominal stroke, 10 mm adjust range, PT port thread, and the -S magnet option with another genuine AirTAC SCJ adjustable-stroke cylinder.
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 SCJ32X20-10S FAQ
At the standard operating pressure of 0.5 MPa, this cylinder provides 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N.
A screw mechanism in the rear cap lets you shorten the stroke end by up to 10 mm. The 20 mm in the model code is the maximum nominal stroke; you can field-adjust it down to 10 mm. It does not change the cylinder's force or speed.
