About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-20S
The AirTAC SAIJ32X195-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. Equipped with a SUS420J2 stainless steel rod and a position magnet, it provides a usable travel window of 175-195 mm, allowing you to dial back the nominal 195 mm stroke by up to 20 mm during commissioning. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
Because the adjuster acts purely as a mechanical stop at the retract end, it sets the end position without holding the load pneumatically. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback. This model uses PT tapered port threads and omits the FB, CA, CB, and CR mounting styles found on some standard cylinders.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-20S Is Used
Commissioning Fine-Tuning
Dial in the exact retract distance within a 175-195 mm window during machine setup, eliminating the need to physically swap cylinders for minor position corrections.
Product Size Changeover
Quickly adjust the end-stop to accommodate varying product lengths on a packaging line, leveraging the 20 mm adjustment range to maintain precise positioning.
Sensor-Verified Positioning
Utilize the integrated magnet with DMSE electronic sensors to confirm the adjusted end position, ensuring repeatable operations in compact assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX195-20S the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires fine end-position tuning without adding external stops; for higher force needs, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The rear adjuster allows a 175-195 mm travel window, making it ideal for product changeovers. If your machine requires true load holding without live air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is a stop, not a lock. For direct replacement, match the 32 mm bore, 195 mm stroke, 20 mm adjustment, PT port, and -S magnet.
With a 195 mm stroke, this cylinder approaches the threshold where side loads become a concern. The 12 mm rod and M10x1.25 thread provide a robust interface, but for unsupported lengths at or near this travel, incorporating an external guide rail will prevent premature seal wear. The mounting hardware is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 Adjustable Cylinder SAIJ32 SAIJ32AX195-20S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from the nominal 195 mm down to 175 mm. It sets the travel end point but does not lock or hold the load without continuous air pressure.
