About the Airtac SCJ32 Standard Cylinder SCJ32X130-75
The SCJ32X130-75 is a 32 mm bore double-acting single-rod cylinder that puts stroke-end fine-tuning directly on the rear cap. A 75 mm adjusting screw lets you shorten the effective stroke from its 130 mm nominal maximum without removing the cylinder or adding external hard stops—ideal for commissioning trials and format changeovers on compact automation cells.
At 0.5 MPa it delivers 402 N push and 345 N pull, with a 12 mm piston rod and PT1/8 ports. The tie-rod body measures 182 mm (A dimension) and includes a 21 mm air cushion for end-of-stroke deceleration. Operating pressure spans 0.15–1.0 MPa, and the standard TPU seal works from -20 to +70 °C.
Airtac SCJ32 Standard Cylinder SCJ32X130-75 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X130-75 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 130 mm |
| Stroke adjustment | Up to 75 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 SCJ32X130-75 Is Used
Commissioning & Setup
Dial in the exact push stroke on a new pick-and-place without cutting rod extensions. The 75 mm screw range covers most trial-and-error adjustments during machine bring-up.
Product Changeover
Quickly reset the stroke end when a packaging line switches between box sizes. One operator can adjust the rear screw in seconds, avoiding mechanical stop changes.
Wear Take-Up
Compensate for gripper pad wear or fixture drift over time by advancing the stroke end slightly. The 75 mm range gives plenty of room for long-term process tweaks.
Is the Airtac SCJ32 Standard Cylinder SCJ32X130-75 the Right Cylinder?
Choose the SCJ32X130-75 when you need to dial in a precise end position within a 55–130 mm window on a 32 mm bore platform. If your load requires more push force, step up to the 40 mm bore SCJ40 series, which provides 628 N at 0.5 MPa. For applications where the stroke is fixed and never needs field adjustment, the simpler SC32 fixed-stroke cylinder reduces cost and overall length.
A direct replacement must match the 32 mm bore, 130 mm nominal stroke, 75 mm adjust range, PT port thread, and basic mounting. If you later add a magnet, specify SCJ32X130-75S to accept CMSG/DMSG sensors. For strokes over 300 mm on any bore, consider an external guide rail or a guided cylinder to protect the rod from side-load bending.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-75)
- ✓ 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 SCJ32X130-75 FAQ
At 0.5 MPa the push force is 402 N and the pull force is 345 N (single-rod area difference). At the maximum operating pressure of 1.0 MPa, push reaches approximately 804 N. Always size for the lower pull force if the cylinder does work in both directions.
Only if you need the adjustable-stroke feature. The SCJ body is longer (182 mm A dimension) to house the adjusting screw. You must match bore, nominal stroke, port thread (PT), and mounting style. The SCJ uses the same mounting accessories as the SC series, except no FB flange or CA/CB clevis.
