About the Airtac SCJ32 Standard Cylinder SCJ32X75-50TC
The SCJ32X75-50 is a 32mm bore, double-acting, single-rod pneumatic cylinder that lets you fine-tune the stroke end position on the machine. A rear-cap adjusting screw provides up to 50mm of retraction from the 75mm nominal maximum, so you can dial in the exact stopping point during commissioning or format changes without swapping the cylinder.
This model delivers 402N of push force and 345N of pull force at 0.5MPa, rising to 724N push at the maximum operating pressure of 0.9MPa. It features a 12mm diameter piston rod, PT1/8 ports, and a 21mm air cushion for smooth deceleration. The body length A(SCJ) is 182mm, and it is supplied with a TC centre trunnion pivot and TCM1 bracket for applications that require the cylinder to swing.
Airtac SCJ32 Standard Cylinder SCJ32X75-50TC Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X75-50TC |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 75 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 SCJ32X75-50TC Is Used
End-Stop Commissioning
Fine-tune the retracted position of a compact clamp or ejector during machine setup. The 50mm adjustment range allows operators to quickly dial in the perfect stroke end without disassembling linkages.
Small-Part Diverter Gates
Adjust the gate opening stroke on a conveyor line to handle different product sizes. The rear screw makes it easy to change the stop point when switching between batches, reducing changeover time.
Wear Take-Up on Stops
Compensate for mechanical wear on an external hard stop in a cycling fixture. The adjustable stroke allows maintenance teams to recover the precise position without replacing the cylinder or the tooling.
Is the Airtac SCJ32 Standard Cylinder SCJ32X75-50TC the Right Cylinder?
Choose the SCJ32 when you need a compact, adjustable-stroke actuator with a push force around 402N at standard plant air. If your load demands more force, step up to the SCJ40, which provides 628N push at 0.5MPa. If your application does not require field-adjustable stroke, a fixed-stroke SC32 cylinder is a simpler, more cost-effective alternative. For a direct replacement, match the 32mm bore, 75mm nominal stroke, 50mm adjustment range, PT port thread, and TC centre trunnion mounting with the F-SC32TC bracket.
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 SCJ32X75-50TC FAQ
At 0.5MPa, the push force is 402N and the pull force is 345N. The maximum push force at the 0.9MPa operating limit is 724N. The pull force is lower because the 12mm piston rod reduces the effective area on the return stroke.
A screw in the rear cap sets the stroke end position. You can shorten the stroke by up to 50mm from the 75mm nominal maximum. It only adjusts the end position; it does not change the cylinder's force or speed. The cylinder must be depressurized before making adjustments.
