About the Airtac SCJ32 Standard Cylinder SCJ32X230-100S
The SCJ32X230-100S is a double-acting, single-rod pneumatic cylinder featuring a rear-cap adjusting screw that provides a 100 mm field-adjustable stroke range, letting you fine-tune the end position without swapping the unit. Its 12 mm diameter rod and M10x1.25 rod thread handle a push force of 402 N at 0.5 MPa, making it a precise actuator for light automation tasks where commissioning or format changes demand on-the-fly stroke modification.
Built with a tie-rod construction and a PT1/8 port, this model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling reliable end-of-stroke detection. The 21 mm air cushion decelerates the piston smoothly, and the body length A(SCJ) of 182 mm provides a compact footprint for integration into space-constrained machines.
Airtac SCJ32 Standard Cylinder SCJ32X230-100S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X230-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 230 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 SCJ32X230-100S Is Used
Commissioning Fine-Tuning
During machine setup, the 100 mm adjustment screw allows technicians to precisely dial in the actuator's stop point for pick-and-place or diverting mechanisms without mechanical rework.
Wear Take-Up on Stops
In packaging lines, the adjustable stroke compensates for wear on end-of-travel dampers over time, maintaining consistent positioning of pusher arms without replacing the cylinder.
Sensor-Ready Light Assembly
The built-in magnet supports CMSG/DMSG sensors for cycle counting in automated screwdriving or dispensing cells, where the stroke is trimmed to match different product heights.
Is the Airtac SCJ32 Standard Cylinder SCJ32X230-100S the Right Cylinder?
Choose the SCJ32X230-100S when you need a 32 mm bore cylinder with a nominal 230 mm stroke that can be shortened by up to 100 mm during setup. If your force requirements increase, stepping up to the 40 mm bore delivers 628 N of push force at the same 0.5 MPa. For applications where the stroke never needs field adjustment, a fixed-stroke SC32 cylinder is a simpler, cost-effective alternative. To replace this unit, match the bore, the 230 mm nominal stroke, the 100 mm adjust range, the PT port thread, and the integrated magnet; the basic mounting style uses no additional bracket. For strokes of this length, ensure the rod is not subjected to significant side loads, or pair the cylinder with an external guide rail to prevent bending.
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 SCJ32X230-100S FAQ
A rear-cap adjusting screw sets the stroke end position. The nominal maximum stroke is 230 mm, and the screw can shorten this by up to 100 mm in the field, giving you an effective stroke range of 130 mm to 230 mm. It adjusts the stop point, not the cylinder's force or speed.
At 0.5 MPa operating pressure, the push force is 402 N and the pull force is 345 N. The push force is higher because the single rod reduces the piston area on the return side. The maximum push force at 0.9 MPa is 724 N.
