About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-20S
The AirTAC SAIJ32X135-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. It provides a usable travel window of 115 to 135 mm without requiring external stops. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance.
This model includes a magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves. The extruded aluminum barrel design omits tie-rods, and the PT tapered G1/8 port ensures a tight pneumatic connection.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-20S Is Used
Machine Changeover
Dial in the exact 115-135 mm end stop during product size transitions without swapping out the physical cylinder.
Assembly Positioning
Fine-tune the retract stroke to perfectly seat small components, leveraging the 345 N pull force at 0.5 MPa.
Lab Automation
The SUS304 stainless steel rod provides the corrosion resistance needed for cleanroom and wet laboratory environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX135-20S the Right Cylinder?
Select this 32 mm bore cylinder when an application requires precise end-position tuning on the fly, which is ideal for machine changeovers compared to a fixed-stroke SAI model. If your process needs greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa.
To match this exact SKU for an ISO 15552 replacement, specify a 32 mm bore, 135 mm stroke, 20 mm adjustment range, PT port thread, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and a magnet for sensors. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air, so consider an SAIL or BSAI cylinder if load-holding is required.
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.
