About the Airtac SCJ32 Standard Cylinder SCJ32X100-50SH
The SCJ32X100-50SH is a 32 mm bore double-acting single-rod cylinder with a field-adjustable stroke end, configurable across a 50 mm range via the rear-cap adjusting screw. It delivers 402 N of push force at 0.5 MPa, making it a compact yet capable actuator for light positioning and clamping tasks that demand fine-tuned end-stop control.
This specific model includes a built-in magnet for barrel-mounted CMSG/DMSG/EMSG sensors and high-temperature Viton (FKM) seals, extending the operating temperature window to 0–150 °C. The 12 mm diameter piston rod and PT1/8 ports are standard for the 32 mm bore, and the body length A(SCJ) is 182 mm, providing a slightly longer envelope than the fixed-stroke SC version to accommodate the adjusting mechanism.
Airtac SCJ32 Standard Cylinder SCJ32X100-50SH Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X100-50SH |
|---|---|
| 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 SCJ32X100-50SH Is Used
Commissioning & Fine-Tuning
The 50 mm adjustment range lets technicians dial in the exact stroke end position during machine setup without machining hard stops, accelerating commissioning on packaging and assembly lines.
Wear Take-Up in Clamping
In light-duty clamping fixtures, the adjustable stroke compensates for part thickness variation or jaw wear over time, maintaining consistent clamping force without reprogramming the PLC.
Small Part Sorting Gates
The 32 mm bore and 100 mm stroke suit compact diverter gates on conveyors; the adjustable end-stop lets operators fine-tune the gate opening to match different product sizes on the fly.
Is the Airtac SCJ32 Standard Cylinder SCJ32X100-50SH the Right Cylinder?
Choose the SCJ32X100-50SH when you need to dial in a precise stroke end position without swapping cylinders—ideal for commissioning trials or format changeovers on small automation cells. If 402 N push force is marginal, stepping up to the 40 mm bore SCJ40 series provides 628 N at the same 0.5 MPa pressure. For applications where the stroke is permanently fixed and the adjusting screw is unnecessary, the standard SC32 fixed-stroke cylinder is a more economical alternative. This unit is a direct replacement for another AirTAC SCJ32 adjustable-stroke cylinder with a 100 mm nominal stroke, 50 mm adjust range, PT ports, basic mount, magnet, and Viton seals.
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 SCJ32X100-50SH FAQ
At the standard 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force (the lower pull force is due to the 12 mm rod reducing the effective piston area). At the maximum operating pressure of 0.9 MPa, push force reaches 724 N.
The SCJ32X100-50SH can replace an SC32 of the same 100 mm nominal stroke if you need the added 50 mm stroke-end adjustment range. However, the SCJ body length A(SCJ) of 182 mm is slightly longer than the standard SC32, so verify the available envelope. Mounting accessories from the SCJ subset (Basic, FA, LB, TC) are required.
