About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X155-100S
The AirTAC SAIJ32X155-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a carbon steel piston rod and a PT tapered port thread. Because this specific SKU carries a 100 mm adjustment code, you can dial back the nominal 155 mm stroke to create a highly flexible 55-155 mm usable travel window.
Delivering 402 N of push force at 0.5 MPa, this 32 mm bore unit is built for fine end-position tuning. The integrated magnet works seamlessly with AirTAC CMSE reed and DMSE solid-state sensors, while the extruded aluminum barrel includes sensor grooves on both sides. Remember that the rear adjuster acts only as a mechanical stop for deceleration, not as a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X155-100S Is Used
Machine Setup & Changeover
Dial in the exact end-position during commissioning or product changeover using the 55-155 mm travel window, eliminating the need for external stopper blocks.
Variable End-Stop Positioning
Ideal for test fixtures and assembly stations where the effective stroke length must be frequently modified to accommodate different part depths.
Light-Duty Clamping
Provides 402 N of precise clamping force at 0.5 MPa, with an integrated magnet for DMSE solid-state sensors to confirm end-of-travel.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X155-100S the Right Cylinder?
Choose this SAIJ32X155-100-S variant when your application requires frequent product-size changeovers or variable end-stops without swapping the cylinder. The 100 mm adjustment range allows massive on-the-fly stroke modifications at commissioning. If you need slightly less force, stepping down is not an option since 32 mm is the smallest bore, but stepping up to a 40 mm bore provides 628 N of push force at 0.5 MPa.
Because the standard SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR), you can easily match your ISO 15552 footprint. For any load-holding requirements without live air pressure, skip this cylinder and look at the SAIL or BSAI series, as the adjuster here does not lock the load.
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 SAIJ32X155-100S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum operating pressure is 1.0 MPa.
The rear external adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 155 mm down to as little as 55 mm. This provides a 55-155 mm adjustable travel window for fine-tuning end positions without replacing the cylinder.
