About the Airtac SCJ32 Standard Cylinder SCJ32X70-10S
The SCJ32X70-10S is a double-acting, single-rod pneumatic cylinder with a 10 mm field-adjustable stroke end, letting you fine-tune the 70 mm nominal stroke without swapping the unit. Its 12 mm diameter rod and M10x1.25 knuckle thread suit light-duty positioning tasks.
At 0.5 MPa, this cylinder delivers 402 N of push force and 345 N on the pull stroke. The built-in magnet allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for end-of-stroke detection. The body length A(SCJ) is 182 mm, and it features a 21 mm air cushion for smooth deceleration.
Airtac SCJ32 Standard Cylinder SCJ32X70-10S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X70-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 70 mm |
| Stroke adjustment | Up to 10 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 SCJ32X70-10S Is Used
Commissioning Trials
The 10 mm adjust range lets technicians fine-tune the end stop during initial machine setup without replacing the cylinder or adding external hard stops.
Small Part Diverting
Adjust the stroke end to match different lane widths on a conveyor, using the sensor magnet to confirm the cylinder has fully retracted or extended.
Wear Compensation
Take up mechanical play in a clamping or pressing fixture over time by incrementally extending the stroke end with the rear adjusting screw.
Is the Airtac SCJ32 Standard Cylinder SCJ32X70-10S the Right Cylinder?
Choose the SCJ32X70-10S when you need to dial in a precise stroke end position within a 10 mm window during commissioning or format changes. If your force requirement grows, the SCJ40 series offers 628 N of push force at the same pressure. For applications needing a fixed, non-adjustable stroke, the standard SC32 series is a direct alternative. A matching replacement must share the 32 mm bore, 70 mm nominal stroke, 10 mm adjust range, PT ports, and the -S magnet option.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ32X70-10S FAQ
A rear-cap screw sets the stroke end position within a 10 mm range. The nominal 70 mm stroke is the maximum; the screw only shortens the extension, not the force or speed.
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The single-rod design means push force is always greater than pull force.
