About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-10S
The AirTAC SAIJ160X650-10-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a substantial 10053N thrust at 0.5 MPa and uses a 40mm SUS304 stainless steel rod with PT tapered ports. The built-in adjuster allows you to fine-tune the usable travel window down from a 650mm nominal stroke to a precise 640-650mm range, eliminating the need to swap components during machine commissioning.
Because this is a profile cylinder with an extruded aluminum barrel, it integrates sensor grooves on both sides for CMSE and DMSE switches. The rear stopper mechanism acts solely as a travel end deceleration point, meaning it cannot hold a load without live air pressure. For applications requiring true load-holding without continuous pneumatic pressure, an external rod lock or the related SAIL pneumatic-lock cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-10S Is Used
Press Stroke Tuning
Dial in the exact 640-650mm end position during press setup to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the travel limit on automated assembly lines when switching between different product sizes or stacking heights.
Heavy Material Handling
Leverage the 10053N push force to move heavy pallets or structural components, fine-tuning the stop point to prevent mechanical crashes.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-10S the Right Cylinder?
Choose this 160mm bore when the 10053N pull force at 0.5 MPa is insufficient, or step down to a 125mm bore offering 6136N if your application has lower force requirements. An adjustable stroke is highly beneficial for product changeovers where exact end-position tuning is required without physically replacing the cylinder or adding external stops. This model includes the -S magnet for electronic DMSE or reed CMSE position sensing.
When configuring an ISO 15552 replacement, match the 160mm bore, 650mm stroke, 10mm adjustment range, PT port thread, and -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Given the 650mm stroke length, the 40mm rod is highly susceptible to side-loading forces; always use an external guide rail to prevent premature seal wear and rod bending.

- ✓ 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 SAIJ160BX650-10S FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. The operational speed range is 30-500 mm/s.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 10mm. This creates a usable travel window between 640mm and 650mm, enabling precise end-position tuning at commissioning without replacing the cylinder.
