About the Airtac SCJ32 Standard Cylinder SCJ32X200-50SH
The SCJ32X200-50SH is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw that provides 50 mm of field-adjustable stroke-end control, letting you fine-tune the 200 mm nominal stroke without swapping the unit. Its 12 mm rod and M10x1.25 knuckle thread suit light-duty positioning, while the 21 mm air cushion decelerates the piston smoothly at end-of-travel.
Built with a Viton (FKM) seal for 0 to +150 °C operation and a built-in magnet for CMSG/DMSG/EMSG sensors, this variant handles hot environments and easy position feedback. At 0.5 MPa it delivers 402 N push and 345 N pull, matching the SC series force profile in a compact tie-rod body with a length A of 182 mm.
Airtac SCJ32 Standard Cylinder SCJ32X200-50SH Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X200-50SH |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 200 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 SCJ32X200-50SH Is Used
Hot-Zone End-Stop Tuning
The 50 mm adjustment screw and Viton seals allow technicians to dial in the exact stroke end on heated packaging platens or drying fixtures without waiting for the machine to cool, reducing setup time.
Small-Part Assembly Fixtures
Fine-tune the push-to-stop position for inserting pins, bushings, or connectors on benchtop assembly cells. The 402 N push force at 0.5 MPa handles light press-fit and insertion tasks reliably.
Wear Take-Up on Clamping Jigs
As clamp pads or tooling wear, use the rear screw to advance the stroke end incrementally, maintaining consistent clamping pressure without reprogramming the PLC or changing mechanical stops.
Is the Airtac SCJ32 Standard Cylinder SCJ32X200-50SH the Right Cylinder?
Choose the SCJ32 when your machine needs a compact, adjustable end-stop within a 50 mm window—ideal for commissioning trials or format changeovers on small assembly fixtures. If you need more push force, step up to the SCJ40 (628 N push at 0.5 MPa); for a fixed stroke with a simpler bill of materials, the standard SC32 is the direct alternative. This model is a direct replacement for any AirTAC SCJ32X200-50SH with PT ports, basic mount, magnet, and Viton seals.
At a 200 mm stroke, rod deflection is minimal under axial loads, but if the application introduces side forces, pair the cylinder with an external linear guide or switch to a guided cylinder to protect the rod bearing and seal.
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 SCJ32X200-50SH FAQ
At 0.5 MPa, the cylinder provides 402 N of push force and 345 N of pull force. The maximum push force at the 0.9 MPa operating limit is 724 N. The pull force is lower because the 12 mm piston rod reduces the effective piston area on the return stroke.
A rear-cap screw lets you shorten the stroke end by up to 50 mm, giving you a 150–200 mm working range. Pick the SCJ when you need to fine-tune the end position during commissioning, accommodate product format changes, or compensate for tooling wear. Choose a fixed-stroke SC32 if your stroke length is permanently fixed and you want a lower-cost, simpler bill of materials.
