Airtac SCJ32 Standard Cylinder SCJ32X300-10S
The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X300-10S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 10 mm range without swapping the cylinder. Ø32mm bore, 300mm nominal stroke, PT1/8 ports and adjustable end cushioning.

About the Airtac SCJ32 Standard Cylinder SCJ32X300-10S
The SCJ32X300-10S is a double-acting, single-rod pneumatic cylinder that puts fine stroke-end adjustment directly on the machine. Its rear-cap screw lets you dial the stroke back by up to 10 mm without removing the cylinder, which is invaluable during commissioning or for taking up mechanical wear over time. The built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the 32 mm bore barrel for reliable end-of-stroke sensing.
With a 12 mm diameter piston rod and PT1/8 ports, this unit delivers 402 N of push force and 345 N of pull force at a standard 0.5 MPa supply. The body length A is 182 mm, and the adjustable air cushion helps decelerate the piston smoothly. It is rated for a maximum standard stroke of 1000 mm, so this 300 mm model operates well within its design envelope.
Airtac SCJ32 Standard Cylinder SCJ32X300-10S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X300-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 300 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 SCJ32X300-10S Is Used
End-Stop Tuning
The 10 mm adjustment screw is ideal for dialing in the precise stopping position on small assembly fixtures, allowing operators to compensate for part tolerance variations without reprogramming a controller.
Sensor Positioning
The built-in magnet works with clamp-on sensors to provide accurate position feedback, making this cylinder suitable for pick-and-place modules where the extend position must be verified after a manual stroke adjustment.
Wear Compensation
In light-duty diverting or stopping gates on conveyor lines, the adjustable stroke can be tweaked periodically to maintain a perfect seal or gate position as mechanical stops and bumpers gradually wear down.
Is the Airtac SCJ32 Standard Cylinder SCJ32X300-10S the Right Cylinder?
Choose the SCJ32X300-10S when your application needs a compact, adjustable-stroke actuator with sensor feedback. If you require more force, stepping up to the 40 mm bore SCJ provides 628 N of push force at the same pressure. For applications where the stroke is fixed and never needs field tuning, the standard SC32X300 is a simpler, cost-effective alternative. This model is a direct replacement for an existing AirTAC SCJ32 cylinder with a 300 mm nominal stroke, a 10 mm adjustment range, PT ports, and a magnet.
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 SCJ32X300-10S FAQ
At 0.5 MPa, the cylinder provides 402 N of push force and 345 N of pull force. The maximum push force at the 0.9 MPa operating limit is 724 N. The pull force is lower because the 12 mm rod reduces the effective piston area on the return stroke.
A rear-cap screw physically limits the piston's extend stroke by up to 10 mm, setting a new mechanical end point. It is a drop-in replacement for an SCJ32 of the same 300 mm nominal stroke and adjustment range. It cannot directly replace a fixed-stroke SC32 unless you need the field-adjustability feature.
