About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-50S
The AirTAC SAIJ32X145-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and provides a usable travel window of 95 to 145 mm, allowing you to dial back the nominal 145 mm stroke by up to 50 mm during commissioning.
This variant features a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports position detection with AirTAC CMSE reed or DMSE electronic solid-state switches.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-50S Is Used
Machine Changeover
Quickly fine-tune the 95-145 mm stroke window during product size changes on a packaging line without replacing the cylinder.
Variable End Stops
Dial in the exact retract position on small-bore assembly fixtures where a fixed 145 mm stroke would crash delicate components.
Lab Positioning
Leverage the SUS304 stainless steel rod and adjustable travel for precise, repeatable end-point tuning in corrosive test environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-50S the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning at machine setup or product changeover without swapping cylinders or adding external stops. If your application requires greater force, stepping up to the 40 mm bore yields 628N of push force at 0.5 MPa. The rear adjuster acts purely as a travel stop and cannot hold a load without live air pressure; for true drop-prevention, consider an AirTAC SAIL or BSAI series cylinder.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints using the Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessory set. It features a 12 mm carbon steel piston rod, M10x1.25 rod threading, G1/8 port, and operates at speeds from 30 to 800 mm/s.
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 SAIJ32BX145-50S FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke by up to 50 mm. This creates a usable travel window of 95 to 145 mm, which is ideal for fine-tuning end positions at commissioning without adding external stops.
At 0.5 MPa operating pressure, it provides 402N of push force and 345N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
