About the Airtac SCJ32 Standard Cylinder SCJ32X150-30S
The SCJ32X150-30S is a 32 mm bore double-acting single-rod cylinder with a field-adjustable stroke end. The rear adjusting screw provides up to 30 mm of stroke shortening, letting you fine-tune the end position from 120 mm to the nominal 150 mm without swapping the cylinder. It delivers 402 N of push force at 0.5 MPa and 724 N at 0.9 MPa, with a 12 mm diameter piston rod.
This model includes a built-in magnet (suffix -S), allowing CMSG/DMSG/EMSG reed or solid-state sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke detection. The standard PT1/8 ports and M10x1.25 rod thread make it a direct fit for compact pneumatic systems. The adjustable cushion decelerates the piston smoothly, and the 182 mm body length keeps the footprint compact.
Airtac SCJ32 Standard Cylinder SCJ32X150-30S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X150-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 150 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 SCJ32X150-30S Is Used
Commissioning & Setup
Fine-tune the end stop during machine commissioning without dismounting the cylinder. The 30 mm adjustment range allows engineers to dial in the exact stroke for pick-and-place or clamping operations.
Format Changeover
Quickly adapt to different product sizes on packaging lines. The rear screw adjusts the stroke end for varying box widths or pallet sizes, reducing changeover time on compact machinery.
Wear Compensation
Compensate for mechanical wear in linkages or tooling over time. The adjustable stroke end lets maintenance teams restore the precise actuator position without replacing parts or adding shims.
Is the Airtac SCJ32 Standard Cylinder SCJ32X150-30S the Right Cylinder?
Choose the SCJ32 when you need a compact, adjustable-stroke cylinder with up to 402 N of push force at 0.5 MPa. If your application demands more force, step up to the 40 mm bore SCJ40, which provides 628 N at the same pressure. For applications where the stroke never needs field adjustment, the fixed-stroke SC32 series is a simpler, cost-effective alternative. This SCJ32X150-30S is a direct replacement for any AirTAC SCJ32 cylinder with a 150 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 SCJ32X150-30S FAQ
A rear-cap adjusting screw sets the stroke end position. You can shorten the nominal 150 mm stroke by up to 30 mm, giving an effective stroke range of 120-150 mm. It adjusts the end stop mechanically and does not change the cylinder's force or speed.
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N. The pull force is lower because the rod reduces the effective piston area on the return stroke.
