About the Airtac SCJ32 Standard Cylinder SCJ32X110-20S
The SCJ32X110-20S is a 32mm bore, double-acting, single-rod pneumatic cylinder that puts fine stroke-end tuning directly in the operator's hands. Its rear-cap adjusting screw provides up to 20 mm of field-adjustable stroke reduction, making it ideal for commissioning trials or format changeovers where the exact end position needs to be dialled in on the machine. With a 12 mm diameter piston rod and PT1/8 ports, this model delivers 402 N of push force at 0.5 MPa.
A built-in magnet is included with the -S suffix, allowing standard CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for reliable, non-contact position sensing. The body length is 182 mm (A dimension), and the cylinder operates smoothly across a 30-800 mm/s speed range with an adjustable air cushion to decelerate the piston at the end of travel.
Airtac SCJ32 Standard Cylinder SCJ32X110-20S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X110-20S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 110 mm |
| Stroke adjustment | Up to 20 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 SCJ32X110-20S Is Used
Commissioning & Setup
Dial in the exact end-stop position during initial machine build-out without re-plumbing or changing the cylinder. The 20 mm screw adjustment lets technicians fine-tune the stroke on the fly.
Wear Take-Up
Compensate for tooling or pad wear over time in light assembly fixtures. A quick turn of the rear screw restores the precise stroke end without disassembling the actuator.
Format Changeover
Adjust the cylinder stroke to handle different product sizes on a packaging or sorting line. The magnetic piston enables sensor-based confirmation of the new end position.
Is the Airtac SCJ32 Standard Cylinder SCJ32X110-20S the Right Cylinder?
Choose the SCJ32X110-20S when you need to fine-tune the stroke end without swapping cylinders or adding external hard stops. If your application requires more force, stepping up to the 40 mm bore provides 628 N of push at the same 0.5 MPa pressure. For fixed-stroke applications where adjustment is not required, the standard SC series offers a simpler, more cost-effective solution. This model is a direct replacement for an AirTAC SCJ adjustable-stroke cylinder of identical 32 mm bore, 110 mm nominal stroke, 20 mm adjust range, PT port thread, and magnetic piston.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-20)
- ✓ 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 SCJ32X110-20S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder produces 402 N of push force and 345 N of pull force. The push force is higher because the single rod reduces the effective piston area on the return stroke.
A threaded screw in the rear cap acts as an internal stroke limiter. Turning the screw changes the retracted end position by up to 20 mm, allowing you to shorten the effective stroke without altering the 110 mm nominal rating or the cylinder's mounting.
