About the Airtac SCJ100 Standard Cylinder SCJ100X500-40
The SCJ100X500-40 is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, providing a 40 mm adjustment range via a rear-cap screw. This 100 mm bore model delivers a substantial 3927 N of push force at 0.5 MPa, making it a powerful actuator for heavy-duty industrial tasks. The 25 mm piston rod and PT1/2 port ensure robust air flow and mechanical strength, while the adjustable air cushion decelerates the 500 mm stroke smoothly.
This genuine AirTAC tie-rod cylinder allows engineers to fine-tune the stroke end position on the machine without swapping the cylinder or adding external hard stops. The adjustment screw shortens the nominal 500 mm stroke by up to 40 mm, which is ideal for commissioning, format changeovers, and compensating for tooling wear. The body length A for this SCJ series is 245 mm, providing a compact footprint for its force class.
Airtac SCJ100 Standard Cylinder SCJ100X500-40 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X500-40 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 500 mm |
| Stroke adjustment | Up to 40 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 SCJ100X500-40 Is Used
Multi-Product Conveyor Stops
A 100 mm bore cylinder provides the high stopping force for heavy pallets on a conveyor. The 40 mm adjustable stroke allows operators to quickly fine-tune the stop position for different pallet sizes during a product changeover.
Press-Fit Depth Adjustment
In a hydraulic replacement or low-pressure press, the SCJ100X500-40 can be set to a precise end-of-stroke depth. The adjusting screw is used during initial setup and later tweaked to compensate for tooling wear, ensuring consistent press-fit quality.
Clamp Stroke Optimization
For a large industrial clamp, the 500 mm stroke provides ample opening clearance. The 40 mm adjustment range lets the commissioning engineer dial in the exact clamping position for a specific workpiece thickness without modifying the machine's PLC program or adding external sensors.
Is the Airtac SCJ100 Standard Cylinder SCJ100X500-40 the Right Cylinder?
Choose the SCJ100X500-40 when you need a high-force, mid-stroke actuator with the flexibility to adjust the end position by up to 40 mm in the field. If your application requires less force, stepping down to an 80 mm bore provides 2513 N of push force at 0.5 MPa. For applications needing a fixed, non-adjustable stroke, the standard SC100X500 is the direct alternative. This model is a direct replacement for any AirTAC SCJ100X500-40 with basic mounting, TPU seals, and PT ports.
For a 500 mm stroke, managing side loads is critical to prevent rod bending and premature seal wear. Ensure the load is guided externally and aligned axially with the piston rod. If external guidance is not feasible, consider using a guided cylinder or integrating a linear slide to absorb transverse forces.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-40)
- ✓ 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 SCJ100X500-40 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. The pull force is lower because the piston rod reduces the effective area on the return stroke. The maximum push force at 0.9 MPa is 7068 N.
Yes, physically it will fit, but the SCJ body is slightly longer to house the adjusting screw. It is a direct functional replacement if you need the added 40 mm stroke adjustment feature. Ensure the mounting, port type (PT), and magnet option match your current setup.
