About the Airtac SCJ40 Standard Cylinder SCJ40X160-100S
The SCJ40X160-100S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, giving you up to 100 mm of fine-tuning range without swapping the unit. Its 40 mm bore delivers 628 N of push force at 0.5 MPa, making it a capable mid-range actuator for positioning tasks that need frequent tweaking.
This model includes a built-in magnet (suffix -S), so CMSG/DMSG/EMSG reed or solid-state sensors clamp directly onto the tie-rod barrel for non-contact position sensing. The 16 mm diameter piston rod, PT1/4 port, and 21 mm air cushion work together for smooth, reliable cycling. The body length A(SCJ) is 185 mm, slightly longer than a fixed-stroke SC of the same bore to house the rear adjusting screw.
Airtac SCJ40 Standard Cylinder SCJ40X160-100S Technical Specifications
| Model | Airtac SCJ40 Standard Cylinder SCJ40X160-100S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø40 mm |
| Nominal stroke | 160 mm |
| Stroke adjustment | Up to 100 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/4 |
| Rod thread | M12×1.25 |
| 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 1200 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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 SCJ40 Standard Cylinder SCJ40X160-100S Is Used
Commissioning & Setup
Fine-tune the end position of a stop gate or pusher during initial machine commissioning without needing to re-drill mounting holes or swap cylinders.
Wear Compensation
In clamping or pressing fixtures, use the 100 mm adjustment screw to take up mechanical wear on tooling or workpieces, maintaining consistent contact force over time.
Format Changeovers
Quickly adjust the stroke of a diverter arm on a packaging line to handle different box sizes, reducing downtime between production runs.
Is the Airtac SCJ40 Standard Cylinder SCJ40X160-100S the Right Cylinder?
Choose the SCJ40X160-100S when your machine setup, format changeover, or wear compensation demands a stroke that can be shortened on the fly by up to 100 mm. If you need more push force, stepping up to the 50 mm bore SCJ delivers 982 N at the same 0.5 MPa pressure. For applications where the stroke is permanently fixed and never needs adjustment, the standard SC40X160 is a simpler, more cost-effective alternative. As a direct replacement, match this unit to another AirTAC SCJ adjustable-stroke cylinder with a 40 mm bore, 160 mm nominal stroke, 100 mm adjustment range, PT thread, and a built-in magnet.
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 SCJ40 Standard Cylinder SCJ40X160-100S FAQ
At the maximum operating pressure of 1.0 MPa, the theoretical push force is 1130 N. At the more common 0.5 MPa, it provides 628 N of push force. The pull force is lower at 528 N due to the area of the 16 mm piston rod.
A screw mechanism in the rear cap allows you to shorten the stroke end position by up to 100 mm. The nominal 160 mm stroke is the maximum. Turning the screw changes where the piston stops on its return, providing a flexible, mechanical end-stop without altering the cylinder's force or speed.
