About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-30
The AirTAC SAIJ32X300-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 402N of push force and 345N of pull force at 0.5 MPa, operating via a G1/8 PT port. By dialing in the 30mm adjustment screw, you achieve a precise 270-300mm usable travel window, perfect for fine-tuning retract end positions during commissioning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses a 12mm rod with an M10x1.25 thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. Because the 300mm stroke is relatively long for a 32mm bore, an external guide is recommended to prevent excessive side loading on the rod.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-30 Is Used
Machine Setup & Changeover
Dial in the exact 270-300mm retract position during product changeovers without machining new stopper blocks or changing the cylinder.
Variable End Stops
Adjust the stroke on the fly to accommodate varying package sizes on a packaging line, ensuring precise positioning every time.
Fixture Alignment
Fine-tune the clamping distance during initial commissioning to perfect part seating, utilizing the 30mm rear adjustment window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-30 the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your application requires exact end-position tuning without swapping out components or adding external stops. If your setup needs greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. The SAIJ32X300-30 is dimensionally interchangeable per ISO 15552, matching standard bore, stroke, PT port, and mounting interfaces.
Keep in mind the rear adjuster functions strictly as a travel stop, not a lock; it cannot hold a load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series. Available mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ32BX300-30 FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It operates at speeds between 30 and 800 mm/s.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective stroke back by up to 30mm, creating a 270-300mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
