About the Airtac SCJ200 Standard Cylinder SCJ200X600-75S
The SCJ200X600-75S is a double-acting, single-rod pneumatic cylinder from the AirTAC SCJ series, featuring a rear-cap adjusting screw that provides a 75 mm field-adjustable stroke range. This allows you to fine-tune the stroke end position without removing the cylinder, making it ideal for commissioning and format changeovers on large-scale equipment. With a 200 mm bore, it generates a substantial 15708 N of push force at 0.5 MPa, driven by a 40 mm diameter piston rod.
This model includes a built-in magnet (suffix -S), enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the tie-rod barrel for reliable end-of-stroke sensing. It uses the standard TPU seal for a -20 to +70°C operating range and PT ports. The body length for this bore is 342 mm (A dimension), with a 33 mm air cushion to decelerate the high-inertia loads typical of this force class.
Airtac SCJ200 Standard Cylinder SCJ200X600-75S Technical Specifications
| Model | Airtac SCJ200 Standard Cylinder SCJ200X600-75S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder (ISO 6430 class) |
| Bore size | Ø200 mm |
| Nominal stroke | 600 mm |
| Stroke adjustment | Up to 75 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT3/4 |
| Rod thread | M36×2 |
| 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 – 500 mm/s |
| Cushion | Adjustable, 33 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 (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 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 SCJ200 Standard Cylinder SCJ200X600-75S Is Used
Heavy Press End-Stop Adjustment
In large hydraulic or pneumatic presses, the 75 mm adjustment range allows operators to quickly change the final pressing depth for different tooling setups or material thicknesses without disassembling the actuator.
Palletizer Pusher Arm Tuning
For palletizing systems handling varied box sizes, the adjustable stroke lets a single SCJ200 cylinder handle multiple format changes, precisely setting the push distance for each product run.
Damper and Valve Actuation
In large-scale water treatment or power generation, this cylinder can actuate heavy dampers or valves, with the stroke adjustment used to fine-tune the open/closed positions during commissioning to ensure a perfect seal.
Is the Airtac SCJ200 Standard Cylinder SCJ200X600-75S the Right Cylinder?
Select the SCJ200X600-75S when you need high force and the ability to dial in the stroke end on the machine. If your application requires even greater force, the next step up is the 250 mm bore, which delivers 24544 N of push at 0.5 MPa. For applications with a fixed, unchanging stroke, a standard SC200X600 cylinder is a more economical choice. This cylinder is a direct replacement for another AirTAC SCJ200X600-75S with a PT port and built-in magnet.
Given the 600 mm stroke length, be mindful of side loading on the 40 mm rod. For applications where the load is not perfectly guided and aligned with the rod axis, an external guide rail or a switch to a guided cylinder is strongly recommended 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 SCJ200 Standard Cylinder SCJ200X600-75S FAQ
The theoretical push force at 0.5 MPa is 15708 N, and the pull force is 15080 N (due to the 40 mm rod). At the maximum operating pressure of 1.0 MPa, the push force reaches 28274 N. Always apply a safety factor for real-world dynamic loads.
Yes, if you need the 75 mm adjustable stroke feature. The SCJ200X600-75S is a direct dimensional replacement for another AirTAC SCJ200 cylinder with the same bore, nominal stroke, and adjust range. It is not dimensionally interchangeable with ISO 15552 cylinders, as it is a tie-rod design.
