About the Airtac SCJ100 Standard Cylinder SCJ100X500-40S
The SCJ100X500-40S is a double-acting, single-rod pneumatic cylinder featuring a rear-cap adjusting screw that allows the effective stroke end to be fine-tuned by up to 40 mm. This field-adjustable design is ideal for commissioning, format changes, or compensating for wear without replacing the cylinder. With a 100 mm bore and 500 mm nominal stroke, it delivers a substantial 3927 N of push force at 0.5 MPa, scaling up to 7068 N at 0.9 MPa.
A built-in magnet is integrated into the piston, enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback. The cylinder uses a 25 mm diameter piston rod, PT1/2 port connections, and features an adjustable air cushion for smooth deceleration.
Airtac SCJ100 Standard Cylinder SCJ100X500-40S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X500-40S |
|---|---|
| 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 SCJ100X500-40S Is Used
Format Changeovers
Quickly adjust the end stop by up to 40 mm when switching between product sizes on a packaging or assembly line, eliminating the need for mechanical hard stops.
Wear Compensation
Compensate for gradual wear on tooling or grippers in material handling systems by dialing in the stroke end with the rear screw, maintaining consistent clamping force.
Commissioning Trials
Fine-tune the actuator's travel during initial machine setup and testing, allowing engineers to optimize the stroke without stocking multiple cylinder lengths.
Is the Airtac SCJ100 Standard Cylinder SCJ100X500-40S the Right Cylinder?
Select the SCJ100X500-40S when you need to fine-tune the stroke end position on a machine without swapping cylinders. If your application requires a fixed stroke, the standard SC100X500 is the direct alternative. For higher push force, step up to the SCJ125 bore, which provides 6136 N at 0.5 MPa; for a more compact footprint, the SCJ80 delivers 2513 N. At a 500 mm stroke, ensure the piston rod is supported against side loads to prevent bending, or consider an external guide unit.
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 SCJ100X500-40S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N due to the 25 mm rod. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 7068 N.
Yes, it replaces another AirTAC SCJ100 with a 500 mm nominal stroke and 40 mm adjust range, matching the PT1/2 port and magnetic piston. The adjustable screw adds length to the rear cap, so verify the envelope space.
