About the Airtac SCJ50 Standard Cylinder SCJ50X110-100
The SCJ50X110-100 is a double-acting, single-rod pneumatic cylinder that provides a field-adjustable stroke end via a rear-cap screw, offering up to 100 mm of adjustment from its 110 mm nominal stroke. This 50 mm bore model delivers 982 N of push force at 0.5 MPa and 1767 N at 0.9 MPa, making it a versatile actuator for applications requiring precise end-position tuning without swapping the cylinder.
Built on a durable tie-rod design with a 20 mm piston rod and PT1/4 ports, the cylinder includes an adjustable air cushion for smooth deceleration. The body length A(SCJ) is 194 mm, and the unit operates reliably on filtered air from 0.15 to 1.0 MPa. This basic configuration comes with a TPU seal, PT threads, and no magnet, providing a robust, cost-effective solution for commissioning and format changeovers.
Airtac SCJ50 Standard Cylinder SCJ50X110-100 Technical Specifications
| Model | Airtac SCJ50 Standard Cylinder SCJ50X110-100 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø50 mm |
| Nominal stroke | 110 mm |
| Stroke adjustment | Up to 100 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 SCJ50X110-100 Is Used
Commissioning & Setup
Dial in the exact end-stop position during machine commissioning without needing to order multiple fixed-stroke cylinders or fabricate external hard stops.
Format Changeovers
Quickly adjust a pusher or stopper cylinder's stroke on a packaging line to handle different box or product sizes, minimizing downtime between batches.
Wear Compensation
Periodically adjust the stroke end to compensate for wear on tooling or gripper pads, maintaining consistent part contact without replacing the actuator.
Is the Airtac SCJ50 Standard Cylinder SCJ50X110-100 the Right Cylinder?
Select the SCJ50X110-100 when you need to fine-tune the stroke end position on the machine, such as during initial setup or for different product sizes. If you require more force, stepping up to a 63 mm bore provides 1559 N of push force at the same 0.5 MPa pressure. For a fixed, non-adjustable stroke, the standard SC series is a simpler, more economical alternative. A direct replacement must match the 50 mm bore, 110 mm nominal stroke, 100 mm adjustment range, PT ports, and basic mounting style.
For this 110 mm stroke, side-loading is generally not a primary concern, but always ensure the load is guided externally and aligned with the rod axis to prevent premature seal wear and rod bending.
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 SCJ50 Standard Cylinder SCJ50X110-100 FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides 982 N of push force and 825 N of pull force. The maximum push force at the 0.9 MPa operating limit is 1767 N.
A threaded screw in the rear cap acts as an internal, adjustable end-stop for the piston. Turning the screw changes the retracted stroke end position by up to 100 mm, allowing you to shorten the effective stroke from the nominal 110 mm maximum without affecting the cylinder's force or speed.
