About the Airtac SCJ32 Standard Cylinder SCJ32X100-50TC
The SCJ32X100-50 is a 32 mm bore, double-acting, single-rod adjustable-stroke cylinder that delivers 402 N of push force at 0.5 MPa. Its rear-cap adjusting screw provides up to 50 mm of stroke-end fine-tuning, allowing machine builders to dial in the exact stop position during commissioning or changeovers without swapping the cylinder. The 12 mm diameter piston rod and M10x1.25 rod thread are standard for this bore, and the PT1/8 port supplies air filtered to 40 µm.
This model is equipped with a TC centre trunnion mount, making it ideal for pivoting applications where the cylinder body needs to swing through an arc. The trunnion bracket (F-SC32TC) is supplied with the cylinder, and the adjustable air cushion decelerates the piston smoothly at both ends. With an operating pressure range of 0.15–1.0 MPa and a standard stroke of 100 mm, it fits compact automation tasks requiring precise, repeatable end-position adjustment.
Airtac SCJ32 Standard Cylinder SCJ32X100-50TC Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X100-50TC |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 100 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 SCJ32X100-50TC Is Used
Commissioning & Setup
The 50 mm adjusting screw lets technicians fine-tune the end-stop position during initial machine setup without removing the cylinder, speeding up the commissioning process for packaging or assembly fixtures.
Format Changeovers
Quickly adjust the stroke end to accommodate different product sizes on a conveyor diverter or sorting gate. The rear screw eliminates the need for external hard stops when switching between formats.
Wear Compensation
In clamping or pressing operations, the adjustable stroke can take up for tooling wear or material thickness variations over time, maintaining consistent contact force without reprogramming the machine.
Is the Airtac SCJ32 Standard Cylinder SCJ32X100-50TC the Right Cylinder?
Choose the SCJ32X100-50 when your application requires a compact 32 mm bore with the ability to fine-tune the stroke end by up to 50 mm on the machine. If you need more force, step up to the 40 mm bore SCJ40 series, which provides 628 N of push at 0.5 MPa. For applications where the stroke is fixed and never needs adjustment, a standard SC32X100 fixed-stroke cylinder eliminates the adjusting screw and is slightly shorter. To replace this unit, match the 32 mm bore, 100 mm nominal stroke, 50 mm adjust range, PT port thread, and TC centre trunnion mounting. Since the nominal stroke is under 300 mm, side-load concerns are minimal, but always align the rod with the load path to prevent premature seal wear.
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 SCJ32X100-50TC FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum operating push force at 0.9 MPa is 724 N. Because it is a single-rod cylinder, the pull force is lower due to the area of the 12 mm rod.
Yes, if your existing cylinder matches the 32 mm bore, 100 mm nominal stroke, 50 mm adjustable range, PT ports, and TC centre trunnion mount. The F-SC32TC trunnion bracket is included. Verify the rod thread (M10x1.25) and port size (PT1/8) match your current setup.
