Airtac Adjustable Cylinder SAIJ32 SAIJ32BX85-10
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX85-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 85mm 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 SAIJ32BX85-10
The AirTAC SAIJ32X85-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 75-85 mm window. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for corrosion resistance and uses a PT tapered port. This 32 mm bore actuator operates at speeds between 30-800 mm/s.
The rear adjuster acts purely as a mechanical stop for end-position tuning during commissioning; it is not a lock, so the cylinder will not hold a load without live air pressure. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX85-10 Is Used
Machine Setup Tuning
Dial in the exact 75-85 mm end position during initial commissioning without adding external physical stops to your fixture.
Product Changeover
Quickly adapt the stroke end-point on a packaging line when switching between slightly different product sizes or thicknesses.
Variable End Stops
Use the rear adjuster screw to set precise retract limits for light-duty 32 mm bore positioning tasks requiring 402 N of force.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX85-10 the Right Cylinder?
Choose this 32 mm bore model when your application requires 402 N of push force at 0.5 MPa, or step up to the 40 mm bore if you need 628 N. The 10 mm adjustment range is ideal for machine setups requiring variable end-stops or product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. For position holding without live air, consider the SAIL or BSAI series instead. To match this ISO 15552 interchangeable cylinder, specify: 32 mm bore, 85 mm stroke, 10 mm adjustment, PT G1/8 port, and no magnet.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX85-10 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw lets you shorten the nominal 85 mm stroke by up to 10 mm, creating a 75-85 mm usable travel window. It functions as a mechanical stop for fine-tuning, not as a lock, so it cannot hold a load without live air pressure.
