About the Airtac SCJ100 Standard Cylinder SCJ100X500-75S
The SCJ100X500-75S is a double-acting, single-rod tie-rod cylinder engineered for applications demanding high force and field-adjustable stroke end positioning. With a 100 mm bore, it delivers a substantial 3927 N of push force at 0.5 MPa, scaling up to 7068 N at the maximum operating pressure of 0.9 MPa. The rear-cap adjusting screw provides a 75 mm range to fine-tune the stroke end, allowing operators to dial in the exact stopping position without dismounting the cylinder or adding external hard stops.
This model includes a built-in magnet (-S suffix), enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for reliable, non-contact piston position feedback. The 25 mm piston rod and PT1/2 ports ensure robust flow for consistent actuation, while the adjustable air cushion, with a 29 mm cushion length, decelerates the 500 mm stroke smoothly. The body length A(SCJ) is 245 mm, making it a compact yet powerful solution for heavy-duty adjustable-stroke tasks.
Airtac SCJ100 Standard Cylinder SCJ100X500-75S Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X500-75S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 500 mm |
| Stroke adjustment | Up to 75 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 SCJ100X500-75S Is Used
Product Diverter Gates
In high-speed sortation systems, the 75 mm adjustment range allows maintenance teams to precisely set the gate's open position for different package sizes, eliminating mechanical shimming and reducing changeover time.
Clamping & Fixturing Stations
For welding or assembly fixtures handling varied part families, the adjustable stroke lets operators quickly set the clamp's final position to accommodate new workpiece dimensions without swapping the cylinder.
Press & Forming Die Cushions
The high 3927 N push force at 0.5 MPa combined with a field-adjustable stroke end makes this cylinder ideal for controlling the depth of a forming die, allowing fine-tuning during commissioning to achieve perfect part geometry.
Is the Airtac SCJ100 Standard Cylinder SCJ100X500-75S the Right Cylinder?
Select the SCJ100X500-75S when your application requires a powerful 100 mm bore cylinder with the ability to fine-tune a 500 mm maximum stroke by up to 75 mm on the machine. If your force requirement is lower, consider stepping down to the 80 mm bore SCJ80 series, which provides 2513 N of push force at 0.5 MPa. For applications where the stroke is fixed and never needs adjustment, the standard SC100 series offers a simpler, more economical solution. A direct replacement must match the 100 mm bore, 500 mm nominal stroke, 75 mm adjust range, PT port thread, and the -S magnet option. For this 500 mm stroke, be mindful of side-loading on the rod; if the load is not guided, use an external guide rail or consider a guided cylinder to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-75)
- ✓ 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 SCJ100X500-75S FAQ
As a single-rod cylinder, push and pull forces differ. At 0.5 MPa, the theoretical push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. These values are based on the 100 mm bore and 25 mm rod diameter.
The rear adjusting screw shortens the stroke end by up to 75 mm from the 500 mm nominal maximum. It is a mechanical stop, not a speed or force control. It can replace an SC100 if you need field-adjustable stroke end positioning, provided the bore, port thread (PT), and sensor option (-S magnet) match your current setup.
