About the Airtac SCJ32 Standard Cylinder SCJ32X100-50
The SCJ32X100-50 is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke, allowing the rear stop position to be shortened by up to 50 mm without removing the unit. This 32 mm bore model delivers 402 N of push force and 345 N of pull force at 0.5 MPa, making it a compact yet capable actuator for light positioning and clamping tasks.
Its M10x1.25 rod thread and PT1/8 ports keep the footprint small, while the 21 mm air cushion at each end protects the end caps during high-cycle operation. The adjustable screw is purely a mechanical stroke-end limiter—it does not alter force or speed—so it is ideal for commissioning fine-tuning, format changeovers, and taking up mechanical wear on the line.
Airtac SCJ32 Standard Cylinder SCJ32X100-50 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X100-50 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 50 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 SCJ32X100-50 Is Used
Commissioning & Setup
The 50 mm adjustment screw lets technicians dial in the exact stroke end-stop during initial machine setup without changing cylinders or adding external hard stops, speeding up line commissioning.
Wear Take-Up on Clamps
On packaging or assembly fixtures, the adjustable stroke compensates for jaw or pad wear over time. Operators can fine-tune the clamping position in seconds to maintain consistent part holding force.
Small-Bore Format Changeover
In light-duty pick-and-place or sorting units, the SCJ32 allows quick stroke length changes between product batches. The screw adjustment provides a repeatable mechanical stop for different box or component sizes.
Is the Airtac SCJ32 Standard Cylinder SCJ32X100-50 the Right Cylinder?
Choose the SCJ32 when you need a compact, adjustable-stroke cylinder in the 402 N push class. If you require more force, step up to the SCJ40 (628 N push at 0.5 MPa) which shares the same 50 mm adjust option. For applications where the stroke is fixed and never needs field adjustment, the standard SC32 is a simpler, more cost-effective alternative. This model is a direct replacement for any AirTAC SCJ32X100-50 with PT ports and basic mounting; ensure the adjust range matches your current setup.
For strokes of 100 mm, side-loading is generally manageable, but always align the rod with the load axis. If the application introduces any radial force, consider an external guide rail or switch to a guided cylinder to protect the rod bearing and piston seal from premature wear.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-50)
- ✓ 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 SCJ32X100-50 FAQ
At the standard operating pressure of 0.5 MPa, this cylinder provides 402 N of push force (extending) and 345 N of pull force (retracting). The pull force is lower because the 12 mm piston rod reduces the effective piston area on the return stroke. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N.
Yes, provided your application can accommodate the slightly longer body length required for the rear adjusting mechanism (body length A is 182 mm). The SCJ32X100-50 offers the same bore, port size (PT1/8), and rod thread (M10x1.25) as the SC32, but adds the ability to shorten the stroke end by up to 50 mm. If you do not need adjustability, the standard SC32 is a direct dimensional match.
