About the Airtac SCJ100 Standard Cylinder SCJ100X500-10S
The SCJ100X500-10S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, delivering 3927 N of push force at 0.5 MPa. Its rear-cap adjusting screw provides a 10 mm fine-tuning range, allowing operators to dial in the precise stroke end position without removing the cylinder from the machine. This model features a 25 mm piston rod and PT1/2 ports, with a body length A of 245 mm.
Built with a tie-rod construction, this cylinder is designed for reliable industrial service on filtered air up to 1.0 MPa. The integrated magnet allows for direct mounting of CMSG, DMSG, or EMSG sensors along the barrel for electronic end-of-stroke detection. The adjustable air cushion at both ends decelerates the piston smoothly, protecting the end caps during high-cycle operations.
Airtac SCJ100 Standard Cylinder SCJ100X500-10S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X500-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 500 mm |
| Stroke adjustment | Up to 10 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 SCJ100X500-10S Is Used
Commissioning & Setup
The 10 mm adjusting screw allows technicians to precisely set the end-of-stroke position during machine commissioning, eliminating the need for shims or external hard stops and saving significant setup time.
Wear Compensation
In high-cycle material handling, the adjustable stroke can be used to take up mechanical wear in tooling or grippers over time, maintaining consistent part contact without reprogramming the controller.
Format Changeovers
For packaging or assembly lines running multiple product sizes, the stroke can be quickly re-adjusted on the fly to accommodate different box heights or part dimensions, reducing changeover downtime.
Is the Airtac SCJ100 Standard Cylinder SCJ100X500-10S the Right Cylinder?
Choose the SCJ100X500-10S when you need a powerful 100 mm bore cylinder with the ability to fine-tune the stroke end by up to 10 mm on the machine, ideal for commissioning and format changeovers. If your application requires a higher force, stepping up to the 125 mm bore provides 6136 N of push force at the same 0.5 MPa pressure. For applications where the stroke is fixed and never needs adjustment, the standard SC100X500 fixed-stroke cylinder is a simpler, more cost-effective alternative.
For this 500 mm stroke length, carefully evaluate side-loading on the 25 mm rod. If the load is not guided externally, the rod may be subject to bending moments. In such cases, use an external guide rail or consider a guided cylinder assembly. This model is a direct replacement for any AirTAC SCJ100X500-10S with PT ports, a basic mount, and a magnet.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ100X500-10S FAQ
At the standard operating pressure of 0.5 MPa, this cylinder provides a push force of 3927 N and a pull force of 3681 N. The push force is greater because the single rod reduces the effective piston area on the return stroke. The maximum push force at 0.9 MPa is 7068 N.
Yes, you can replace an SC100X500 with this SCJ100X500-10S if you need the adjustable stroke feature. The mounting footprint and port locations are identical. Ensure you match the port thread (PT), and note that this model includes a magnet for sensors, which the original may not have had.
