About the Airtac SCJ32 Standard Cylinder SCJ32X600-100S
The SCJ32X600-100S is a 32mm bore double-acting, single-rod cylinder with a field-adjustable stroke, providing up to 100mm of end-position fine-tuning on its 600mm nominal stroke. This model delivers 402 N of push force at 0.5 MPa and features a 12mm diameter piston rod with M10x1.25 threads, making it a precise actuator for light to medium automation tasks.
The rear-cap adjusting screw allows operators to dial in the exact stroke end without dismounting the cylinder, which is invaluable during commissioning or for accommodating part variations. This unit includes a built-in magnet, enabling direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors along the tie-rod body for reliable end-of-stroke detection. The body length A is 182mm plus stroke.
Airtac SCJ32 Standard Cylinder SCJ32X600-100S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X600-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 600 mm |
| Stroke adjustment | Up to 100 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 SCJ32X600-100S Is Used
Commissioning & Setup
The 100mm adjustment range lets technicians fine-tune the end-stop position on a new machine without fabricating custom hard stops, speeding up factory acceptance testing.
Wear Compensation
On a conveyor diverter gate, the adjustable stroke can be periodically shortened to compensate for wear on a pusher pad, maintaining consistent part placement over time.
Format Changeovers
In a small packaging cell, operators can quickly adjust the stroke of a label applicator arm via the rear screw to handle different product heights, minimizing downtime between batches.
Is the Airtac SCJ32 Standard Cylinder SCJ32X600-100S the Right Cylinder?
Choose this 32mm bore SCJ for applications needing up to 402 N of push force at standard plant pressure. If your load requires more power, stepping up to the 40mm bore provides 628 N of push force at the same 0.5 MPa. For tasks where the stroke length is fixed and never needs field changes, the standard SC fixed-stroke cylinder offers a simpler, more compact alternative.
For this 600mm stroke, be mindful of side-loading which can cause rod bending. If the load is not guided externally, consider pairing the cylinder with an external guide rail or switching to a guided cylinder assembly. As a direct replacement, match this unit with another SCJ32X600-100S with a PT port, basic mount, and the -S magnet option.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-100)
- ✓ 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 SCJ32X600-100S FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum push force at the 0.9 MPa operating limit is 724 N. Because it is a single-rod cylinder, the pull force is always lower due to the area of the 12mm rod.
A screw mechanism in the rear cap acts as an internal, adjustable end-stop. You can shorten the stroke end by up to 100mm from the 600mm nominal maximum. It only adjusts the stroke length, not the cylinder's force or speed.
