About the Airtac SCJ50 Standard Cylinder SCJ50X160-30S
The SCJ50X160-30S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, giving you 30 mm of fine-tuning range from the nominal 160 mm maximum. With a 20 mm diameter piston rod and a push force of 982 N at 0.5 MPa (1767 N at 0.9 MPa), it delivers the muscle needed for mid-range clamping, pressing, and positioning tasks where the final stop point must be dialled in precisely during commissioning or changeover.
A built-in magnet (the -S suffix) allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The body length A(SCJ) is 194 mm, and the adjustable air cushion decelerates the piston smoothly at both ends. This model uses the default TPU seals and PT ports, suiting standard industrial air supplies from -20 to +70 °C.
Airtac SCJ50 Standard Cylinder SCJ50X160-30S Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X160-30S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 160 mm |
| Stroke adjustment | Up to 30 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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 SCJ50 Standard Cylinder SCJ50X160-30S Is Used
Commissioning & Setup
Fine-tune the end-of-stroke position by up to 30 mm without re-mounting the cylinder, speeding up machine commissioning and eliminating the need for shims or custom stops.
Format Changeovers
Quickly adjust a stop gate or pusher for different product sizes on a packaging line. The 30 mm range handles multiple SKUs with a simple screw adjustment, not a cylinder swap.
Wear Compensation
In clamping or pressing fixtures, take up pad wear or material thickness variation over time by advancing the stroke end, maintaining consistent clamping force without replacing tooling.
Is the Airtac SCJ50 Standard Cylinder SCJ50X160-30S the Right Cylinder?
Step up to the 63 mm bore SCJ if your application demands more force; the SCJ63 delivers 1559 N of push at the same 0.5 MPa. If your stroke is fixed and never needs field adjustment, the standard SC50X160 is a simpler, slightly shorter alternative. For replacement, match the bore (50 mm), nominal stroke (160 mm), and the 30 mm adjust range (-30). This model includes a magnet, so your replacement must also carry the -S suffix. The basic mounting style accepts FA front flange or LB foot accessories from the F-SC50 series.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ 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 SCJ50 Standard Cylinder SCJ50X160-30S FAQ
At the standard operating pressure of 0.5 MPa, it generates 982 N of push force and 825 N of pull force. The maximum push force at 0.9 MPa is 1767 N. Because it is a single-rod cylinder, the push force is always greater than the pull force due to the rod area.
Yes, if you need the 30 mm stroke-end adjustability. The SCJ50X160-30S shares the same bore, rod, and port dimensions as the SC50, but the body is slightly longer to house the adjusting screw. Ensure your mounting and sensor setup accommodates the SCJ's 194 mm body length.
