About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-50S
The AirTAC SAIJ160X190-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 140-190 mm usable travel window, allowing you to dial back the nominal 190 mm stroke by up to 50 mm during commissioning. Belonging to the 160 mm bore class, it delivers substantial thrust with 10053 N pull force at 0.5 MPa and 18095 N push at 0.9 MPa.
This carbon-rod unit includes a -S magnet for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting. Because the rear adjuster acts purely as a mechanical stop and does not hold the load without live air, you must use a SAIL or BSAI cylinder for pneumatic locking applications.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-50S Is Used
Press Fitment Tuning
Dial in the exact 140-190 mm insertion depth for heavy press operations without swapping cylinders or adding external mechanical stops.
Product Changeover
Quickly adjust the rear stopper by up to 50 mm to accommodate varying product lengths on automated assembly lines.
End-Stop Calibration
Fine-tune the retract end position during machine setup to perfect timing and avoid hard impacts, leveraging the 30-500 mm/s speed range.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X190-50S the Right Cylinder?
Select this 160 mm bore model when an application requires heavy force and variable end-positioning without external stops. If your thrust requirements are lower, stepping down to a 125 mm bore yields 5734 N pull at 0.5 MPa. The 50 mm adjustment range is ideal for accommodating product size changes on a line. As an ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, featuring a PT tapered G3/4 port, a 50 mm cushion, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). For any stroke of 300 mm or more, an external guide is recommended to manage side loads, though this 190 mm unit handles moderate loads well with its 40 mm rod.
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 SAIJ160X190-50S FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N pull force and 14074 N push force at 0.7 MPa. The maximum push force is 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that shortens the effective travel from 190 mm down to 140 mm. It is a travel stop, not a lock, so it will not hold the load without live air pressure.
