About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-20S
The AirTAC SAIJ160X195-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel window down to 175 mm from its 195 mm nominal length. Built with a robust 40 mm carbon steel rod and a PT tapered port thread, it delivers massive thrust up to 18095 N at 0.9 MPa, making it ideal for heavy-duty positioning tasks.
This variant includes a magnet for use with AirTAC CMSE reed and DMSE electronic sensors, fitting neatly into the standard sensor grooves on both sides of the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to dial in the end position during commissioning without swapping hardware; it is not a lock, so live air is required to hold the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-20S Is Used
Heavy Press Tuning
Dial in the exact 175-195 mm end position during heavy press commissioning to accommodate varying material thicknesses without external stopper hardware.
Product Changeover
Rapidly adjust the stroke end-stop on automated lines when switching between different product sizes, utilizing the 20 mm rear adjustment range.
High-Force Positioning
Leverage the 18095 N push force to move heavy pallets or tooling into exact alignment, relying on the 40 mm carbon steel rod for durability.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-20S the Right Cylinder?
Choose this 160 mm bore when you need significantly more force than the 100 mm bore provides (7068 N push at 0.9 MPa), but less than the massive 3204 kgf output of the 200 mm version. The adjustable stroke is highly beneficial for machine setups requiring precise end-stop tuning during product changeovers, avoiding the need to bolt on external stoppers or buy a different fixed-stroke SAI cylinder.
Because this cylinder uses a PT tapered port thread and includes the -S magnet, ensure your pneumatic fittings and sensor arrays match these specifications. For any application requiring the load to be held in place without continuous air pressure, this adjustable stopper will not suffice; you should consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead. Additionally, for any stroke length of 300 mm or more, an external guide is recommended to manage side-load stress on the 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 SAIJ160X195-20S FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 9425 N. The maximum force at 1.0 MPa is 2050 kgf.
The rear adjuster screw allows you to shorten the 195 mm nominal stroke by up to 20 mm, providing an effective travel window of 175-195 mm. It functions as a mechanical stop for end-position tuning and is not a locking mechanism.
