About the Airtac SCJ100 Standard Cylinder SCJ100X500-50
The SCJ100X500-50 is a double-acting, single-rod pneumatic cylinder delivering 3927 N of push force at 0.5 MPa from its 100 mm bore. A rear-cap adjusting screw provides up to 50 mm of stroke-end reduction, allowing you to fine-tune the 500 mm nominal stroke directly on the machine without swapping the cylinder or adding external hard stops.
This tie-rod cylinder uses a 25 mm diameter piston rod with an M20x1.5 male thread and PT1/2 ports. Its adjustable air cushion decelerates the piston across a 29 mm cushion length, protecting end caps during high-cycle operation. The body length (A dimension) is 245 mm, making it a compact solution for heavy-duty adjustable-position applications.
Airtac SCJ100 Standard Cylinder SCJ100X500-50 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X500-50 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 500 mm |
| Stroke adjustment | Up to 50 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/2 |
| Rod thread | M20×1.5 |
| 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, 29 mm |
| Max stroke | Up to 1500 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SCJ100 Standard Cylinder SCJ100X500-50 Is Used
Format Changeovers
Quickly adjust the end stop for different product sizes on packaging or filling lines, reducing downtime between batches.
Clamping & Pressing
Dial in the exact pressing depth for glue curing or assembly fixtures, compensating for part tolerance variations.
Commissioning Trials
Fine-tune actuator travel during machine setup and testing without needing multiple fixed-stroke cylinders on hand.
Is the Airtac SCJ100 Standard Cylinder SCJ100X500-50 the Right Cylinder?
Choose the SCJ100X500-50 when your application needs a robust, field-tunable end position within a 50 mm window. If you require more force, stepping up to the 125 mm bore provides 6136 N of push force at the same 0.5 MPa. For a fixed, non-adjustable stroke, the standard SC100X500 cylinder is a direct alternative with the same force output and mounting footprint. This model is a direct replacement for any AirTAC SCJ100X500-50 with PT ports and basic mounting. For strokes of 500 mm, always check for potential rod buckling under high side loads; if lateral forces are present, an external guide rail or a guided cylinder should be used to protect the rod and bearing.
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 SCJ100 Standard Cylinder SCJ100X500-50 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. The maximum push force at the 0.9 MPa operating limit is 7068 N. Because it is a single-rod cylinder, the push force is always higher than the pull force.
Yes, provided the mounting and porting match. The SCJ100X500-50 shares the same 100 mm bore, PT1/2 ports, and basic mounting footprint as the SC100 series, but adds the rear adjusting screw. Ensure you have clearance for the slightly longer body length (245 mm) to accommodate the stroke adjustment mechanism.
