Airtac Adjustable Cylinder SAIJ32 SAIJ32BX60-20S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX60-20S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 60mm 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 SAIJ32BX60-20S
The AirTAC SAIJ32X60-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 32 mm bore and a 60 mm nominal stroke, yielding a usable travel window of 40 to 60 mm. This adjustment capability allows you to fine-tune the retract end-position at commissioning without adding external stops. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod (option B) and includes a magnet for position sensing.
This model uses PT tapered port threads and is fully dimensionally interchangeable with ISO 15552 cylinders. The rear adjuster acts purely as a mechanical stop to set the travel end; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports AirTAC CMSE reed and DMSE electronic switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX60-20S Is Used
End-Position Tuning
Dial in the exact retract distance within the 40-60 mm window during machine commissioning without swapping out the physical cylinder.
Product Changeover
Quickly adapt the end-stop for different part sizes on a conveyor line using the rear adjustment screw instead of repositioning hard stops.
Assembly Clamping
Apply up to 402 N of precise clamping force at 0.5 MPa while making micro-adjustments to the stroke to accommodate material thickness variations.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX60-20S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa. If you need less force, stepping down to a 20 mm bore is an option, while moving up to a 40 mm bore provides 628 N at the same pressure. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot provide.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 60 mm stroke, 20 mm adjustment range, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Since the stroke is under 300 mm, the 12 mm rod handles standard side loads well without needing an external guide.

- ✓ 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 SAIJ32BX60-20S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. At the maximum pressure of 1.0 MPa, it can deliver up to 801 N of push force.
The rear adjuster screw lets you shorten the effective stroke by up to 20 mm. For this 60 mm stroke model, it creates an adjustable travel window between 40 mm and 60 mm, allowing precise end-position tuning without external stops.
