Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-30
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 80mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-30
The AirTAC SAIJ32X80-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 50-80 mm usable travel window by allowing you to trim the 80 mm nominal stroke back by up to 30 mm. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This variant uses a SUS304 stainless steel rod for corrosion resistance and PT tapered port threads. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure. For load-holding without continuous air, consider an external pilot-operated check valve or the AirTAC SAIL lock series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-30 Is Used
Machine Changeover
Dial in the 50-80 mm travel window during product size changes without swapping the cylinder or repositioning hard stops.
End-Position Tuning
Fine-tune the retract stroke end at commissioning to absorb mechanical tolerances and achieve exact positioning.
Light-Duty Clamping
Apply 402 N of push force for securing delicate components, using the rear screw to set the exact clamping depth.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX80-30 the Right Cylinder?
Choose this 32 mm bore when 402 N of thrust at 0.5 MPa is sufficient, or step up to the 40 mm bore if you need 628 N. The adjustable stroke is selected over a fixed SAI cylinder when you need to fine-tune the retract end during commissioning or product changeover without adding external stops. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. To match ISO 15552 replacements, ensure the 80 mm stroke, 30 mm adjustment, PT G1/8 port, and standard rod configuration align.

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.
