Airtac SCJ32 Standard Cylinder SCJ32X150-40
The AirTAC Airtac SCJ32 Standard Cylinder SCJ32X150-40 is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 40 mm range without swapping the cylinder. Ø32mm bore, 150mm nominal stroke, PT1/8 ports and adjustable end cushioning.

About the Airtac SCJ32 Standard Cylinder SCJ32X150-40
The SCJ32X150-40 puts 402 N of push force at 0.5 MPa into a compact 32 mm bore body, with a rear adjusting screw that lets you shorten the stroke end by up to 40 mm without removing the cylinder. Its 12 mm piston rod and M10x1.25 rod thread handle light positioning and clamping tasks, while the 21 mm air cushion decelerates the load quietly.
Because the effective stroke is field-adjustable, one SCJ32X150-40 can replace several fixed-stroke trial cylinders during commissioning or cover multiple product formats on a single machine. The tie-rod construction and PT1/8 ports keep it simple to plumb into existing circuits, and the body length A of 182 mm plus stroke fits neatly into guarded areas.
Airtac SCJ32 Standard Cylinder SCJ32X150-40 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X150-40 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 150 mm |
| Stroke adjustment | Up to 40 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 SCJ32X150-40 Is Used
Commissioning & Setup
Dial in the exact stroke end during machine bring-up by turning the rear screw through the 40 mm range, eliminating the need to swap cylinders or fabricate shims.
Format Changeover
Quickly re-set the push stroke for different box sizes or product widths on a packaging line without touching the PLC program or mechanical hard stops.
Wear Take-Up
Compensate for gripper pad wear or seal compression over time by advancing the stroke end slightly, keeping the tooling in full contact without replacing parts.
Is the Airtac SCJ32 Standard Cylinder SCJ32X150-40 the Right Cylinder?
Step up to the 40 mm bore if your application needs more than 402 N push at 0.5 MPa—the SCJ40 delivers 628 N at the same pressure. For purely fixed-stroke applications where the adjust screw adds unnecessary length, the standard SC32 is a simpler alternative. If side load is a concern, pair the cylinder with an external guide or switch to a guided cylinder.
When replacing an existing SCJ32X150-40, match the bore, 150 mm nominal stroke, 40 mm adjust range, PT1/8 ports, and basic mounting. For a magnet-equipped version, order SCJ32X150-40S to accept CMSG/DMSG sensors.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-40)
- ✓ 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 SCJ32X150-40 FAQ
At 0.5 MPa the cylinder delivers 402 N pushing and 345 N pulling (the pull force is lower because the 12 mm rod reduces the piston area on the return side). At the maximum operating pressure of 0.9 MPa, push force reaches 724 N.
Only if you need the adjustable stroke feature. The SCJ body is slightly longer than the SC of the same nominal stroke to house the adjusting screw. If you need exactly 150 mm fixed stroke and the extra length is a problem, the standard SC32X150 is the direct fit.
