About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-50S
The AirTAC SAIJ160X180-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 130-180 mm window. This made-to-order configuration utilizes a SUS304 stainless steel piston rod and PT tapered ports, making it highly suitable for demanding industrial environments.
Unlike a fixed-stroke SAI cylinder, this model integrates an external stopper screw at the rear for precise end-position tuning during commissioning or product changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and because this unit includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for position feedback.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 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 SAIJ160 Adjustable Cylinder SAIJ160BX180-50S Is Used
Heavy Press Tuning
Dial in the exact 130-180 mm end-stop for large stamping or press operations, ensuring precise contact without overtravel.
Product Changeover
Quickly adjust the stroke window on packaging lines when product sizes change, eliminating the need to physically swap out the entire cylinder.
Assembly Station Setup
Fine-tune the retraction end position during initial machine commissioning to perfectly align heavy 160 mm bore tooling components.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX180-50S the Right Cylinder?
The 50 mm adjustment range is ideal for machinery requiring variable end-stops without physically swapping cylinders or adding external mechanical stops. For stroke lengths of 300 mm or more, an external guide is recommended to manage side-load, though this 180 mm stroke remains well within standard limits.
When specifying an ISO 15552 replacement, match the 160 mm bore, 180 mm nominal stroke, 50 mm adjustment code, PT port thread, and -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster functions strictly as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider 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 SAIJ160 Adjustable Cylinder SAIJ160BX180-50S FAQ
The operational speed range for this bore size is 30-500 mm/s.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 50 mm from the 180 mm nominal stroke, creating a usable 130-180 mm window. It only sets the end position and does not lock the load without live air pressure.
