About the Airtac SCJ32 Standard Cylinder SCJ32X165-50S
The SCJ32X165-50S is a double-acting, single-rod pneumatic cylinder from AirTAC, featuring a rear adjusting screw that provides a 50 mm range for fine-tuning the stroke end. This allows machine builders to dial in the exact end position on the fly without swapping the cylinder, which is invaluable during commissioning or for format changeovers. With a 32 mm bore and a nominal 165 mm stroke, it delivers 402 N of push force at 0.5 MPa, rising to 724 N at the 0.9 MPa maximum operating pressure.
This model includes a built-in magnet (suffix -S), enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for precise, contactless position sensing. The cylinder uses a 12 mm diameter piston rod with an M10x1.25 thread, PT1/8 ports, and a 21 mm air cushion to decelerate the piston smoothly. Its body length A(SCJ) is 182 mm, and it operates within a standard temperature range of -20 to +70 °C with TPU seals.
Airtac SCJ32 Standard Cylinder SCJ32X165-50S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X165-50S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 165 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 SCJ32X165-50S Is Used
Commissioning & Setup
The 50 mm rear adjustment screw lets technicians fine-tune the actuator's end stop precisely during initial machine setup, eliminating the need for shims or custom mechanical stops.
Small Part Ejection
Ideal for a packaging line where the push distance for ejecting different-sized products must be adjusted quickly. The magnetic piston allows sensors to verify full extension and retraction.
Test & Measurement Fixtures
Used in a test rig where the stroke length must be calibrated for different samples. The 724 N max push force at 0.9 MPa provides ample power for clamping or pressing small components.
Is the Airtac SCJ32 Standard Cylinder SCJ32X165-50S the Right Cylinder?
Choose the SCJ32X165-50S when you need a compact, adjustable-stroke actuator with sensor feedback. The 50 mm adjustment range is ideal for applications where the end position may need to be tweaked after installation. If you require more force, stepping up to the 40 mm bore provides 628 N of push at 0.5 MPa. For a fixed, non-adjustable stroke, the standard SC32 series is a simpler and more cost-effective alternative. This unit is a direct replacement for any AirTAC SCJ32 cylinder with a 165 mm nominal stroke, a 50 mm adjust range, PT ports, and a magnetic piston.
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 SCJ32X165-50S FAQ
At the standard 0.5 MPa operating pressure, it produces 402 N of push force and 345 N of pull force. The maximum push force at 0.9 MPa is 724 N. Because it is a single-rod cylinder, the push force is greater than the pull force due to the area of the 12 mm rod.
No, this double-acting cylinder will not hold its position if air pressure is exhausted or the directional valve is centered. The piston will drift or drop under load. If load holding is required in a power-off state, you must add an external rod lock, brake, or a pilot-operated check valve to the circuit.
