About the Airtac SCJ100 Standard Cylinder SCJ100X60-30S
The SCJ100X60-30S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke, delivering 3927 N of push force at 0.5 MPa. Its rear-cap adjusting screw provides up to 30 mm of stroke-end reduction, allowing precise fine-tuning of the piston stop position without replacing the cylinder or adding external hard stops. The 25 mm piston rod and PT1/2 ports suit medium-to-heavy force applications requiring on-machine adjustability.
This model includes a built-in magnet (-S suffix), enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for reliable end-of-stroke or mid-stroke position feedback. With a 29 mm air cushion and a body length A of 245 mm, it offers smooth deceleration. The maximum operating pressure is 1.0 MPa, yielding a theoretical push force of 7068 N.
Airtac SCJ100 Standard Cylinder SCJ100X60-30S Technical Specifications

|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 60 mm |
| Stroke adjustment | Up to 30 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 SCJ100X60-30S Is Used
Format Changeovers
Quickly dial in a new end-stop position for different product sizes on packaging or filling lines, using the 30 mm adjustment range to avoid mechanical change parts.
Commissioning & Setup
Fine-tune the actuator stroke during machine commissioning to perfectly align tooling or stops, eliminating the need to shim or modify mounting brackets.
Wear Compensation
Adjust the stroke end to take up mechanical wear in grippers or linkages over time, maintaining precise positioning without replacing the entire cylinder.
Is the Airtac SCJ100 Standard Cylinder SCJ100X60-30S the Right Cylinder?
Choose the SCJ100 bore when your application needs around 3927 N of push force at standard shop air. If you require a more compact package and can accept lower force, stepping down to an 80 mm bore provides 2513 N of push at 0.5 MPa. For applications where the stroke length is fixed and never needs field adjustment, the standard SC100 fixed-stroke cylinder is a simpler, more cost-effective alternative. This SCJ100X60-30S is a direct replacement for an existing AirTAC SCJ adjustable-stroke cylinder of the same 100 mm bore, 60 mm nominal stroke, and 30 mm adjustment range, with PT ports, basic mounting, and a magnet.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ 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 SCJ100X60-30S FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. The maximum operating pressure is 1.0 MPa, which provides a theoretical push force of 7068 N. The push force is greater than the pull force because it is a single-rod cylinder.
A screw in the rear cap sets the retracted end position of the piston. You can shorten the nominal 60 mm stroke by up to 30 mm. It only adjusts the stroke end; it does not change the cylinder's force, speed, or the forward end position.
