About the Airtac SCJ40 Standard Cylinder SCJ40X100-10
The SCJ40X100-10 is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, offering a 10 mm adjustment range via a rear-cap screw. With a 40 mm bore and 16 mm rod, it delivers 628 N of push force at 0.5 MPa, making it a precise actuator for applications requiring fine end-position tuning without swapping the cylinder.
This tie-rod cylinder features a PT1/4 port, M12x1.25 rod thread, and a 21 mm air cushion for smooth deceleration. The body length (A dimension) is 185 mm, providing a compact yet robust solution for commissioning trials or format changeovers where the stroke end must be dialed in on the machine.
Airtac SCJ40 Standard Cylinder SCJ40X100-10 Technical Specifications
| Model | Airtac SCJ40 Standard Cylinder SCJ40X100-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø40 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 10 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 SCJ40X100-10 Is Used
Commissioning & Setup
The 10 mm rear adjustment screw lets technicians dial in the exact stroke end position during machine commissioning, eliminating the need for shims or external hard stops on a 40 mm bore actuator.
Product Format Changeover
Quickly adapt the 100 mm nominal stroke for different product sizes on a packaging line by adjusting the screw, reducing downtime between batches without replacing the cylinder.
Wear Compensation
In clamping or pressing fixtures, the adjustable stroke compensates for tooling wear over time, maintaining consistent contact pressure from the 628 N push force without reprogramming the machine.
Is the Airtac SCJ40 Standard Cylinder SCJ40X100-10 the Right Cylinder?
Choose the SCJ40X100-10 when you need to fine-tune the stroke end position by up to 10 mm during setup or production. If your force requirement is lower, stepping down to a 32 mm bore reduces push force to 402 N at 0.5 MPa; for more power, the 50 mm bore provides 982 N. For a direct replacement, match the 40 mm bore, 100 mm nominal stroke, 10 mm adjust range, PT port thread, and basic mounting. If the stroke is fixed and never needs field adjustment, the standard SC series offers a simpler, cost-effective alternative.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ40X100-10 FAQ
At 0.5 MPa, the push force is 628 N and the pull force is 528 N. The maximum push force at the 0.9 MPa operating limit is 1130 N. Because this is a single-rod cylinder, push force is always greater than pull force.
A rear-cap screw sets the stroke end position within a 10 mm range from the 100 mm nominal maximum. Pick the SCJ when you need to fine-tune the end position on the machine for setup, changeovers, or wear take-up. If your stroke is permanently fixed, the standard SC cylinder is the better choice.
