About the Airtac SCJ32 Standard Cylinder SCJ32X60-20S
The SCJ32X60-20S is a compact double-acting, single-rod cylinder that puts fine stroke tuning directly on the machine. Its rear-cap adjusting screw provides up to 20 mm of stroke-end adjustment from the 60 mm nominal maximum, letting you dial in the exact end position during commissioning or format changes without swapping the cylinder. The built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke detection.
With a 12 mm piston rod and PT1/8 ports, this 32 mm bore unit delivers 402 N of push force at 0.5 MPa and up to 724 N at the maximum operating pressure of 0.9 MPa. The body length A(SCJ) is 182 mm, and the adjustable air cushion provides smooth deceleration over a 21 mm cushion length. It is a genuine AirTAC pneumatic component built for repeatable, field-configurable linear motion.
Airtac SCJ32 Standard Cylinder SCJ32X60-20S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X60-20S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 60 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 SCJ32X60-20S Is Used
Commissioning & Setup
The 20 mm adjustment range allows technicians to fine-tune the stroke end position on a new machine without fabricating custom stops, speeding up initial setup and debugging.
Wear Compensation
In clamping or pressing fixtures, the adjusting screw can be advanced to take up mechanical wear on tooling or workpieces, maintaining consistent clamp force without reprogramming.
Format Changeover
Quickly adapt the cylinder's end stop for different product sizes on a packaging or labeling line. The magnetic piston enables sensor-based confirmation of the new position.
Is the Airtac SCJ32 Standard Cylinder SCJ32X60-20S the Right Cylinder?
Choose the SCJ32 when you need a compact adjustable-stroke cylinder in the 402 N push class at 0.5 MPa. If your application demands more force, step up to the SCJ40, which provides 628 N of push at the same pressure. For fixed-stroke applications where end-position adjustment is not required, the standard SC32 cylinder is a simpler, lower-cost alternative. This SCJ32X60-20S is a direct replacement for any AirTAC SCJ32 adjustable-stroke cylinder with a 60 mm nominal stroke, 20 mm adjustment range, PT ports, basic mounting, and a built-in magnet.
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 SCJ32X60-20S FAQ
The push force is 402 N at 0.5 MPa and 724 N at 0.9 MPa. The pull force is lower due to the single rod, delivering 345 N at 0.5 MPa. The adjusting screw sets the stroke end position and does not alter the cylinder's force output.
A screw in the rear cap limits the piston's retraction stroke. You can shorten the effective stroke by up to 20 mm from the 60 mm nominal maximum. This is a mechanical end-stop adjustment for commissioning and format changes; it is not a force or speed control.
