About the Airtac SCJ32 Standard Cylinder SCJ32X100-30
The SCJ32X100-30 is a 32mm bore double-acting single-rod cylinder with a rear adjusting screw that provides up to 30mm of field-adjustable stroke reduction. This allows fine-tuning of the end position without swapping the cylinder, delivering 402N of push force at 0.5 MPa.
Weighing the compact 12mm rod diameter and M10x1.25 rod thread, this model suits light-duty positioning tasks. The 21mm air cushion decelerates the piston smoothly, and the body length A(SCJ) is 182mm, making it a direct dimensional match for genuine AirTAC SCJ32 replacements requiring this specific adjustable range.
Airtac SCJ32 Standard Cylinder SCJ32X100-30 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X100-30 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 30 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 SCJ32X100-30 Is Used
Commissioning Fine-Tuning
Adjust the 30mm screw during machine setup to perfectly align the cylinder end stop with a mating part, eliminating the need for shims or external hard stops.
Wear Take-Up on Stops
On a small divert gate, the adjustable stroke compensates for pad wear over time, maintaining consistent actuation without immediate replacement.
Small Part Ejection
Set the precise ejection depth for a 32mm bore pusher, with the 30mm range allowing for quick changeover between different component thicknesses.
Is the Airtac SCJ32 Standard Cylinder SCJ32X100-30 the Right Cylinder?
Choose the SCJ32X100-30 when you need to dial in a precise end stop on a 32mm bore platform. If the 402N push force at 0.5 MPa is marginal, stepping up to the SCJ40 series provides 628N. For applications where the stroke is fixed after commissioning, the standard SC32X100 fixed-stroke cylinder removes the adjustment mechanism for a simpler, lower-cost option. The exact replacement match is another AirTAC SCJ32X100-30 with PT ports and basic mounting.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ 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 SCJ32X100-30 FAQ
A rear-cap screw lets you shorten the stroke end by up to 30mm. The nominal 100mm stroke is the maximum; turning the screw limits how far the piston extends, giving you a field-adjustable range from 70mm to 100mm.
At 0.5 MPa, push force is 402N and pull force is 345N. At the maximum operating pressure of 0.9 MPa, push force reaches 724N. This is a single-rod cylinder, so push force is always higher than pull force.
