Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-20
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 100mm 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 SAIJ32X100-20
The AirTAC SAIJ32X100-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 100 mm stroke that can be dialed back by up to 20 mm, giving you a precise 80-100 mm usable travel window for commissioning without external stops. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty tasks.
This model features a 12 mm carbon steel rod with an M10x1.25 thread, and its extruded aluminum barrel includes sensor grooves on both sides. The rear adjuster acts purely as a travel stop for end-position tuning and deceleration; it does not hold the load without live air. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-20 Is Used
End-Position Tuning
Dial in the exact 80 to 100 mm travel distance during machine commissioning to perfect stopping points without adding external physical stops.
Product Changeover
Quickly adapt the cylinder's stroke window on packaging lines when handling slightly different product sizes, minimizing downtime.
Light Assembly Tasks
Utilize the 402 N push force for precise pressing or lightweight component placement that requires exact positional depth control.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X100-20 the Right Cylinder?
Choose this 32 mm bore when your application requires roughly 402 N of push force at 0.5 MPa. If you need less force, a smaller option is unavailable in this series, but stepping up to a 40 mm bore yields 628 N. The adjustable stroke is perfect for machine setups requiring variable end-stops on the fly rather than swapping a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 100 mm stroke, PT tapered port threads, and mounting choice from the available Basic, FA, LB, TC, FTC, TCM1, or TCM2 set. Since this model lacks the -S magnet option, it cannot host CMSE or DMSE sensors. At a 100 mm stroke, side-load is minimal, but always guide the load on longer travels.
Quick checklist
- ✓ 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 SAIJ32X100-20 FAQ
A rear external adjusting screw acts as a stopper, allowing you to shorten the effective travel from 100 mm down to 80 mm. This provides a 20 mm tuning window at commissioning without replacing the cylinder.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
