About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-50S
The AirTAC SAIJ200X475-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 425 to 475 mm, allowing you to dial back the nominal 475 mm stroke by up to 50 mm during commissioning. This bore generates massive thrust, pushing 21991 N and pulling 15080 N at 0.7 MPa, making it suitable for heavy-duty press operations.
Equipped with a standard magnet (-S), it supports AirTAC CMSE reed and DMSE solid-state sensors via the dual-sided extruded aluminum barrel grooves. The robust 40 mm carbon steel rod with an M36x2 thread handles high side loads, while the PT tapered ports ensure a secure pneumatic seal under high flow demands.

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 SAIJ200X475-50S Is Used
Heavy-Duty Press Tuning
Fine-tune the 425-475 mm stroke end-position precisely during machine commissioning to accommodate varying material thicknesses in heavy pressing operations.
Product Size Changeover
Quickly dial in a new retract stop for different product dimensions on a high-force assembly line without disassembling the cylinder mount.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-50S the Right Cylinder?
An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops for product size changeovers without physically swapping the cylinder or adding external stops. For a direct ISO 15552 replacement, match the 475 mm stroke, 50 mm adjustment, PT G3/4 ports, and the -S magnet.
Because the 475 mm stroke is long, an external guide is required to prevent rod deflection and premature seal wear. Remember that the rear adjuster is a travel stop, not a lock; a plain SAIJ cannot hold a load without live air. For fail-safe load holding, use an external rod lock or explore the SAIL or BSAI series.
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 SAIJ200X475-50S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the nominal 475 mm down to 425 mm. It only sets the end-position and deceleration; it does not lock the load without continuous live air pressure.
