About the Airtac SCJ32 Standard Cylinder SCJ32X150-100S
The SCJ32X150-100S is a double-acting, single-rod pneumatic cylinder featuring a rear-cap adjusting screw that provides up to 100 mm of stroke-end adjustability, letting you fine-tune the 150 mm nominal stroke on the fly. With a 12 mm diameter piston rod and PT1/8 ports, it delivers 402 N of push force at 0.5 MPa and up to 724 N at the maximum operating pressure of 0.9 MPa.
This model includes a built-in magnet (suffix -S), allowing CMSG, DMSG, or EMSG sensors to be clamped directly onto the tie-rod barrel for reliable, non-contact position sensing. The body length A(SCJ) is 182 mm, and the adjustable air cushion decelerates the piston smoothly at the end of its travel, protecting the end cap during high-cycle applications.
Airtac SCJ32 Standard Cylinder SCJ32X150-100S Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X150-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 150 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 SCJ32X150-100S Is Used
Commissioning & Setup
The 100 mm adjustment range allows engineers to dial in the exact stroke end position during machine commissioning without swapping cylinders or machining external hard stops, saving hours of setup time.
Product Changeover
On packaging or assembly lines, operators can quickly adjust the stroke to accommodate different product sizes or formats, minimizing downtime between batches with a simple turn of the rear screw.
Wear Compensation
In clamping or pressing fixtures, the adjustable stroke can be periodically extended to compensate for tooling wear or material compression, maintaining consistent process force without replacing the actuator.
Is the Airtac SCJ32 Standard Cylinder SCJ32X150-100S the Right Cylinder?
Choose the SCJ32 bore for compact automation tasks requiring up to 724 N of push force. If your application demands more power, stepping up to the SCJ40 bore provides 628 N of push force at the same 0.5 MPa pressure. For applications where the stroke length never needs field adjustment, the fixed-stroke SC32 cylinder is a simpler, more cost-effective alternative. This SCJ32X150-100S is a direct replacement for any AirTAC SCJ32 cylinder with a 150 mm nominal stroke, 100 mm adjust range, PT ports, and a magnet sensor.
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 SCJ32X150-100S FAQ
A screw mechanism in the rear end cap acts as an internal stop for the piston. By turning the screw, you can shorten the stroke end by up to 100 mm from the 150 mm maximum. This adjusts the physical stopping point of the piston, not the air pressure or speed.
The theoretical push force is 402 N at 0.5 MPa and 724 N at 0.9 MPa. The pull force is lower due to the 12 mm rod area, providing 345 N at 0.5 MPa. Always consider the pull force when sizing for retraction tasks.
