About the Airtac SCJ32 Standard Cylinder SCJ32X275-30S
The SCJ32X275-30S is a double-acting, single-rod pneumatic cylinder that puts stroke-end fine-tuning directly in your hands. Its rear-cap adjusting screw provides a 30 mm adjustable range, letting you dial in the exact stopping position without swapping the cylinder or adding hard stops. With a 12 mm rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa, rising to 724 N at the maximum operating pressure of 0.9 MPa.
This model includes a built-in magnet, so standard CMSG, DMSG, or EMSG reed and solid-state sensors clamp directly onto the tie-rod barrel for reliable end-of-stroke sensing. The 21 mm air cushion at each end decelerates the piston smoothly, protecting the end caps during high-cycle operation. Body length A is 182 mm plus the stroke, making it a compact choice for space-constrained adjustable-stroke tasks.
Airtac SCJ32 Standard Cylinder SCJ32X275-30S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X275-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 275 mm |
| Stroke adjustment | Up to 30 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 SCJ32X275-30S Is Used
Commissioning & Setup
Fine-tune the end position during machine commissioning without removing the cylinder. The 30 mm screw adjustment allows rapid, precise setup of gripper or pusher strokes on new assembly lines.
Product Changeover
Quickly adapt the stroke for different product sizes on a packaging line. The adjustable rear screw lets operators shift the stop position by up to 30 mm in seconds, minimizing downtime between batches.
Wear Compensation
Compensate for mechanical wear in linkages or tooling over time. The adjustable stroke end can be tweaked to restore precise positioning without replacing the entire cylinder, extending the service life of the machine.
Is the Airtac SCJ32 Standard Cylinder SCJ32X275-30S the Right Cylinder?
Choose the SCJ32 when you need a field-adjustable stroke in the 32 mm bore class, where push force starts at 402 N 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 applications that do not require stroke adjustability, the fixed-stroke SC32 offers a simpler, more cost-effective solution. This SCJ32X275-30S is a direct replacement for any AirTAC SCJ32 cylinder with a 275 mm nominal stroke, 30 mm adjust 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 (-30)
- ✓ 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 SCJ32X275-30S FAQ
At 0.5 MPa, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N. The rear adjusting screw only changes the stroke end position and does not affect the cylinder's output force.
Yes, if you need the 30 mm stroke adjustability. The SCJ32X275-30S has the same bore, port size (PT1/8), and rod thread (M10x1.25) as the SC32. Ensure your mounting and sensor setup are compatible, and note that the SCJ body is slightly longer to accommodate the adjusting mechanism.
