About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-50S
The AirTAC SAIJ200X80-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. Its 50mm adjustment screw allows you to trim the 80mm nominal stroke back, creating a precise 30-80mm usable travel window for exact end-position tuning. This built-in stopper eliminates the need to swap cylinders or bolt on external stops during product changeovers.
As an extruded aluminum profile cylinder, it features sensor grooves on both sides and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state switches. The robust 40mm carbon steel rod and M36x2 thread handle high side loads, while the PT tapered port threads ensure a secure, leak-free pneumatic connection.

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 SAIJ200X80-50S Is Used
Heavy Press Tuning
Fine-tune the 30-80mm pressing depth on heavy machinery without changing the cylinder, ensuring precise force application for different material thicknesses.
Product Changeover
Quickly dial in the end-stop position during production line size changes, using the rear adjuster to accommodate varying part dimensions on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-50S the Right Cylinder?
Choose this 200mm bore cylinder when an application demands extreme force, as stepping down to a 160mm bore drops the 0.5 MPa push force to 10053N. The adjustable stroke is ideal for machines requiring variable end-stops or fine commissioning tweaks without replacing hardware. Keep in mind the rear adjuster acts strictly as a travel stop, not a lock; the SAIJ200X80-50-S cannot hold a load without live air, so utilize a SAIL or BSAI cylinder if load-holding is required.
For an exact ISO 15552 replacement, match the 200mm bore, 80mm stroke, 50mm adjustment, PT ports, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 80mm stroke is relatively short for this bore, side-load stress is minimized compared to longer strokes, but an external guide remains recommended for heavy payloads.
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 SAIJ200X80-50S FAQ
It can reach a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 80mm nominal stroke by up to 50mm, providing a usable travel window between 30mm and 80mm. It functions as a mechanical stop for end-position tuning and is not a locking device.
