About the Airtac SCJ50 Standard Cylinder SCJ50X160-50S
The SCJ50X160-50S is a double-acting, single-rod pneumatic cylinder that puts stroke-end fine-tuning directly in the hands of the machine builder. With a 50 mm bore and a 20 mm diameter piston rod, it delivers 982 N of push force at 0.5 MPa (1767 N at 0.9 MPa), while the rear adjusting screw lets you shorten the effective stroke by up to 50 mm without dismounting the cylinder or adding external hard stops.
This model includes a built-in magnet (-S suffix), so CMSG, DMSG, or EMSG reed and solid-state sensors clamp directly onto the tie-rod barrel for reliable end-of-stroke detection. The body length A(SCJ) is 194 mm, and the adjustable air cushion decelerates the piston smoothly over the last 21 mm of travel. Operating pressure spans 0.15–1.0 MPa with filtered air, and the standard PT port is PT1/4.
Airtac SCJ50 Standard Cylinder SCJ50X160-50S Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X160-50S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 160 mm |
| Stroke adjustment | Up to 50 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 SCJ50X160-50S Is Used
Commissioning & Setup
Fine-tune the stroke end position by up to 50 mm on the machine during initial build and debug, eliminating the need to swap cylinders or fabricate custom stops.
Format Changeover
Adjust the actuator throw quickly when a packaging or assembly line switches between product sizes, reducing downtime and mechanical rework.
Wear Compensation
Take up mechanical play or tooling wear over time by advancing the stroke end screw, maintaining precise end-position repeatability without replacing the cylinder.
Is the Airtac SCJ50 Standard Cylinder SCJ50X160-50S the Right Cylinder?
Choose the SCJ50X160-50S when your application needs a 50 mm bore force class and the ability to dial in the stroke end during commissioning or changeover. If you need more push, stepping up to the 63 mm bore SCJ63 provides 1559 N at 0.5 MPa; for a lighter, more compact solution, the 40 mm bore SCJ40 delivers 628 N. The 50 mm adjustable range is ideal for format changes or wear take-up on medium-stroke actuators.
For a direct replacement, match an AirTAC SCJ adjustable-stroke cylinder with the same 50 mm bore, 160 mm nominal stroke, -50 adjust range, PT1/4 port, and built-in magnet. If your motion does not require field adjustment, the fixed-stroke SC50X160 is a simpler, lower-cost alternative. At this 160 mm stroke, rod deflection is minimal, but for high side loads or guided motion, pair the cylinder with an external linear guide or consider a guided cylinder series.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-50)
- ✓ 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 SCJ50X160-50S FAQ
At 0.5 MPa, the cylinder produces 982 N pushing and 825 N pulling. At the maximum operating pressure of 0.9 MPa, push force reaches 1767 N. The pull force is lower because the 20 mm rod reduces the effective piston area on the return stroke.
A rear-cap adjusting screw lets you shorten the stroke end by up to 50 mm from the nominal 160 mm maximum. Choose the SCJ when you need to fine-tune the end position on the machine—for commissioning, format changes, or wear take-up. If the stroke is fixed and never needs field adjustment, the standard SC series is a more economical choice.
