About the Airtac SCJ32 Standard Cylinder SCJ32X75-40
The SCJ32X75-40 is a double-acting, single-rod pneumatic cylinder with a rear-cap adjusting screw that provides up to 40 mm of field-adjustable stroke reduction. This lets you dial in the exact stroke end position for commissioning, format changes, or wear compensation without swapping the cylinder. Its 12 mm diameter piston rod and M10x1.25 rod thread are matched to the 32 mm bore, and the PT1/8 port supplies the filtered air.
At 0.5 MPa, this cylinder delivers 402 N of push force and 345 N on the pull stroke, reflecting the single-rod area differential. The body length A is 182 mm, and the adjustable air cushion decelerates the piston smoothly over the final 21 mm of travel. This is a tie-rod cylinder, not an ISO 15552 profile unit, so dimensional interchangeability is limited to other AirTAC SCJ32 models.
Airtac SCJ32 Standard Cylinder SCJ32X75-40 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X75-40 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 75 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 SCJ32X75-40 Is Used
End-Stop Calibration
During machine commissioning, the 40 mm adjustment screw allows technicians to fine-tune the actuator's stop point to perfectly align with tooling or fixtures, eliminating the need for shims or custom hard stops.
Product Format Changeover
On a packaging line, operators can quickly re-set the stroke end to accommodate different box sizes or product heights, reducing downtime between batches without any mechanical disassembly.
Wear Compensation
In clamping or pressing applications, the adjustable stroke can be periodically extended to compensate for wear on gripper pads or tooling surfaces, maintaining consistent clamping force over the life of the fixture.
Is the Airtac SCJ32 Standard Cylinder SCJ32X75-40 the Right Cylinder?
Choose the SCJ32X75-40 when you need a compact, adjustable-stroke actuator in the 400 N push class. If you require more force, step up to the 40 mm bore SCJ40 series, which provides 628 N push at the same 0.5 MPa pressure. For a fixed, non-adjustable stroke, the standard SC32 cylinder is a simpler, lower-cost alternative. The adjustable stroke is ideal for applications where the end position must be precisely tuned after installation.
For replacement, match this model with another AirTAC SCJ32 cylinder having a 75 mm nominal stroke and a 40 mm adjust range, with PT ports and basic mounting. If you need position sensing, the -S magnet option allows CMSG/DMSG sensors to be mounted directly on the tie-rod barrel.
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 SCJ32X75-40 FAQ
The push force is 402 N at 0.5 MPa and 724 N at the maximum operating pressure of 0.9 MPa. The pull force is lower due to the rod area, providing 345 N at 0.5 MPa. The adjusting screw does not alter the cylinder's force output; it only limits the stroke end position.
Yes, provided the mounting and porting match. The SCJ32 body is slightly longer (A=182 mm) to house the adjusting mechanism. Ensure the 40 mm adjustment range is sufficient for your application, and verify that the PT1/8 port and M10x1.25 rod thread are compatible with your existing connections.
