About the Airtac SCJ32 Standard Cylinder SCJ32X175-100
The SCJ32X175-100 is a double-acting, single-rod pneumatic cylinder with a rear-cap adjusting screw that provides a full 100 mm of field-adjustable stroke-end control, letting you fine-tune the 175 mm nominal stroke without swapping the unit. Its 32 mm bore delivers 402 N of push force at 0.5 MPa, and the 12 mm diameter piston rod threads into an M10x1.25 knuckle, making it a compact yet precise actuator for light automation tasks.
This tie-rod cylinder uses PT1/8 ports and includes a 21 mm air cushion to decelerate the piston smoothly. With a body length A of 182 mm, it fits neatly into space-constrained assemblies. The adjustable screw only sets the stroke end position—it does not alter output force or speed—so it is ideal for commissioning trials, format changeovers, or taking up mechanical wear on a production line.
Airtac SCJ32 Standard Cylinder SCJ32X175-100 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X175-100 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 175 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 SCJ32X175-100 Is Used
Commissioning & Setup
During machine bring-up, the 100 mm adjust range lets technicians dial in the exact stroke end for gripper close positions or ejector extensions without cutting and re-threading rod ends.
Wear Take-Up on Stops
In high-cycle diverting gates, the screw can be periodically advanced to compensate for wear on the external mechanical stop, maintaining precise part placement without replacing the cylinder.
Format Changeover
When a packaging line switches between product sizes, the adjustable stroke allows a quick mechanical change of the pusher stroke length, reducing changeover time compared to fixed-stroke cylinders.
Is the Airtac SCJ32 Standard Cylinder SCJ32X175-100 the Right Cylinder?
Step up to the SCJ40 bore for 628 N of push force at 0.5 MPa if this 32 mm model's 402 N is marginal for your payload. If your application does not require a field-changeable stroke, the fixed-stroke SC32 series offers the same force and mounting footprint at a lower cost. For direct replacement, match the 32 mm bore, 175 mm nominal stroke, 100 mm adjust range, PT1/8 ports, and basic mounting style. At this 175 mm stroke, ensure the rod is guided externally if side loads are present, as a long, unguided single rod can experience bending moments.
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 SCJ32X175-100 FAQ
At the standard 0.5 MPa operating pressure, the push force is 402 N and the pull force is 345 N. At the maximum 0.9 MPa, the push force reaches 724 N. The pull force is always lower because the rod reduces the effective piston area on the return stroke.
You can, provided the 100 mm adjustment range does not interfere with your mechanism. The SCJ body is slightly longer than a comparable SC to house the adjusting screw. Ensure the mounting, port size (PT1/8), and rod thread (M10x1.25) match your existing setup.
