About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X50-20S
The AirTAC SAIJ200X50-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster and a piston magnet. It provides a 30-50 mm usable travel window by allowing you to trim up to 20 mm from the 50 mm nominal stroke.
This model features a carbon steel rod and PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure.

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 SAIJ200X50-20S Is Used
Heavy Press Tuning
Dial in the exact 30-50 mm end position for high-force pressing and forming operations during machine setup.
Product Changeover
Quickly adjust the travel stop to accommodate varying material thicknesses on a heavy-duty conveyor line.
Assembly Station Setup
Fine-tune the clamping reach during initial commissioning without needing to install secondary external stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X50-20S the Right Cylinder?
Choose this 200 mm bore if you require maximum thrust up to 15708 N at 0.5 MPa; stepping down to a 160 mm bore yields 10053 N, which may be insufficient for heavy loads. The adjustable stroke is ideal for fine-tuning the end position during commissioning or product changeover without swapping the cylinder or adding external stops. For load-holding without live air, use a SAIL or BSAI cylinder instead, as the adjuster here is a stop, not a lock. To match this ISO 15552 replacement exactly, specify the 200 mm bore, 50 mm stroke, 20 mm adjustment, PT ports, and the -S magnet.
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 SAIJ200X50-20S FAQ
The 50 mm nominal stroke can be adjusted back by up to 20 mm, providing a usable travel window of 30 to 50 mm.
A rear screw acts as a mechanical stop to trim the travel end for commissioning. It is not a lock, so the cylinder will not hold its load without live air pressure; use a SAIL or BSAI model for positive holding.
