About the Airtac SCJ32 Standard Cylinder SCJ32X500-100
The SCJ32X500-100 is a double-acting, single-rod AirTAC pneumatic cylinder with a field-adjustable stroke, delivering 402 N of push force at 0.5 MPa. Its rear-cap adjusting screw provides up to 100 mm of stroke-end reduction, letting you fine-tune the 500 mm nominal stroke for precise commissioning or format changes without swapping the cylinder.
This 32 mm bore tie-rod cylinder uses a 12 mm diameter piston rod with an M10x1.25 thread and PT1/8 ports. The adjustable air cushion decelerates the piston over the final 21 mm of travel. With a body length of 182 mm plus the stroke, it is a compact solution for applications requiring on-machine stroke adjustment within a 30-800 mm/s speed range.
Airtac SCJ32 Standard Cylinder SCJ32X500-100 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X500-100 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 500 mm |
| Stroke adjustment | Up to 100 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 SCJ32X500-100 Is Used
Commissioning & Setup
The 100 mm adjustment range allows technicians to quickly fine-tune the end-of-stroke position during machine commissioning, eliminating the need to fabricate custom shims or swap cylinders to achieve the exact stopping point.
Wear Compensation
On high-cycle clamping or pressing fixtures, the adjustable stroke can be periodically extended to compensate for mechanical wear on tooling or contact surfaces, maintaining consistent clamping force without immediate part replacement.
Product Changeover
For packaging or assembly lines handling multiple product sizes, the rear screw enables operators to quickly reset the cylinder's stroke end for a new format, significantly reducing changeover time compared to fixed-stroke actuators.
Is the Airtac SCJ32 Standard Cylinder SCJ32X500-100 the Right Cylinder?
Choose the SCJ32X500-100 when you need to dial in the exact stroke end position on a 32 mm bore platform. If your force requirement increases, stepping up to the 40 mm bore SCJ provides 628 N of push at the same 0.5 MPa pressure. For applications where the stroke is fixed and never needs field adjustment, the standard SC32X500 is a simpler, cost-effective alternative. This SCJ model is a direct replacement for another AirTAC SCJ32 adjustable-stroke cylinder with a 500 mm nominal stroke, 100 mm adjust range, PT ports, and basic mounting. For this 500 mm stroke length, ensure the rod is not subjected to high side loads; if lateral forces are present, couple the cylinder with an external guide rail or switch to a guided cylinder series.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ32X500-100 FAQ
At the standard operating pressure of 0.5 MPa, this 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 pull force is lower due to the area of the 12 mm piston rod.
Yes, if you need the adjustable stroke feature. The SCJ shares the same mounting footprint and port size as the SC series. To replace an existing SCJ, match the 32 mm bore, 500 mm nominal stroke, 100 mm adjust range, PT thread, and basic mounting configuration. The SCJ body is slightly longer than the fixed-stroke SC to accommodate the adjusting screw mechanism.
