About the Airtac SCJ40 Standard Cylinder SCJ40X160-100STC
The SCJ40X160-100STC is a double-acting, single-rod pneumatic cylinder that puts stroke-end tuning directly in your hands. Its rear adjusting screw provides a full 100 mm of adjustment range, letting you dial in the exact 160 mm maximum stroke for commissioning or format changes without swapping the cylinder. With a 16 mm rod and PT1/4 ports, it delivers 628 N of push force at 0.5 MPa, making it a versatile workhorse for medium-duty automation.
This model comes ready for pivoting applications with a built-in magnet (-S) for sensor feedback and a centre trunnion mount (TC) supplied with the TCM1 bracket. The body length A is 185 mm, and the adjustable air cushion decelerates the piston smoothly at the end of travel. It's a genuine AirTAC component built for reliable, repeatable motion control.
Airtac SCJ40 Standard Cylinder SCJ40X160-100STC Technical Specifications
| Model | Airtac SCJ40 Standard Cylinder SCJ40X160-100STC |
|---|---|
| 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 SCJ40X160-100STC Is Used
Format Changeovers
Quickly adjust the end stop by up to 100 mm to accommodate different product sizes on packaging or assembly lines, minimizing downtime between batches.
Commissioning & Setup
Fine-tune the actuator's stroke on a new machine during initial setup without needing to order multiple fixed-stroke cylinders, saving time and inventory costs.
Wear Compensation
Compensate for mechanical wear in tooling or grippers over time by slightly extending the stroke end position, maintaining consistent process quality.
Is the Airtac SCJ40 Standard Cylinder SCJ40X160-100STC the Right Cylinder?
Choose the SCJ40 when your application requires up to 628 N of push force at 0.5 MPa. If you need more power, step up to the SCJ50 bore, which provides 982 N of push force at the same pressure. For applications that don't require field-adjustable stroke, a fixed-stroke SC40 cylinder is a simpler, cost-effective alternative. The 100 mm adjustment range on this model is ideal for processes with significant format variations or wear take-up requirements.
To replace this cylinder, match it with another SCJ adjustable-stroke cylinder of 40 mm bore, a 160 mm nominal stroke, and a 100 mm adjustment range (-100). Ensure the replacement has a centre trunnion mount (F-SC40TC), a built-in magnet (-S), and PT ports. For strokes of 300 mm or more, assess the side load on the 16 mm rod; an external guide or a guided cylinder may be necessary to prevent rod bending and ensure long seal life.
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 SCJ40X160-100STC FAQ
At 0.5 MPa, this 40 mm bore cylinder generates 628 N of pushing force and 528 N of pulling force. The maximum push force at the 0.9 MPa operating limit is 1130 N.
Yes, but only if you need the adjustable stroke feature. The SCJ40X160-100STC has a slightly longer body (A=185 mm) than a fixed SC40 to house the adjusting screw. Ensure your mounting arrangement, which here includes a centre trunnion (TC), has clearance for the longer body and the adjustment mechanism.
