About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-50S
The AirTAC SAIJ200X75-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suited for heavy-duty pressing or clamping. The built-in magnet enables position detection with CMSE reed or DMSE electronic sensors.
This specific SKU provides a 75 mm nominal stroke that can be dialed back by up to 50 mm, creating a precise 25-75 mm usable travel window for exact end-position tuning. It features a carbon steel rod, PT tapered ports, and variable air cushions at both ends to decelerate the heavy 40 mm diameter rod. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-50S Is Used
Heavy Press Tuning
Dial in the exact 25-75 mm travel window on a heavy-duty press to accommodate material thickness variations without swapping out the entire cylinder.
Product Changeover
Quickly adjust the rear stopper on a packaging line to handle different product sizes, reducing machine setup time and avoiding external stop hardware.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-50S the Right Cylinder?
When matching this for an ISO 15552 replacement, verify the 75 mm stroke, 50 mm adjustment range, PT port threads, and the -S magnet requirement. Although the 75 mm stroke is relatively short, the heavy moving mass of a 200 mm bore cylinder means the adjuster strictly acts as a travel stop and the air cushions manage deceleration; neither will hold the load without live air. For fail-safe load holding, consider an AirTAC SAIL or BSAI variant. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-50S FAQ
The rear adjusting screw acts as a mechanical stopper that allows you to shorten the effective stroke by up to 50 mm. This turns the 75 mm nominal stroke into a 25-75 mm usable travel window, which can be fine-tuned during commissioning. The adjuster is a stop, not a lock, and requires live air to hold position.
At the maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf of push force.
