Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-50
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 280mm 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 SAIJ32BX280-50
The AirTAC SAIJ32X280-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 50 mm. This creates a highly usable 230-280 mm adjustable window, letting you dial in the exact retract end-position during commissioning without swapping out the cylinder or adding external mechanical stops. It delivers 402 N of push force at 0.5 MPa and utilizes a PT tapered port thread.
Built with a SUS304 stainless steel rod (option B), this 32 mm bore unit is equipped with variable air cushions at both ends to manage impact deceleration. The extruded aluminum barrel includes sensor grooves on both sides for mounting DMSE solid-state or CMSE reed switches, though this specific SKU is configured without a standard magnet. The rear adjuster functions strictly as a travel stop for position tuning, not as a load-holding lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-50 Is Used
Changeover Calibration
Dial in the 230-280 mm retract position during product size changeovers without disassembling the machine or adding external spacers.
End-Stop Tuning
Use the 50 mm rear adjuster to precisely set the final resting position of the 32 mm rod, compensating for mechanical wear over time.
Variable Product Diverter
Adjust the actuation distance on the fly to accurately divert packages of varying lengths on a packaging line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX280-50 the Right Cylinder?
Choose this 32 mm bore if your application requires 402 N of push force at 0.5 MPa; stepping down is not an option in this series, but moving up to a 40 mm bore provides 628 N if your payload increases. The 50 mm adjustment range is ideal for machinery that undergoes frequent product changeovers, allowing the end-stop to be fine-tuned on the fly versus a fixed-stroke SAI cylinder. To match this ISO 15552 footprint for a direct replacement, verify the 280 mm stroke, 50 mm adjuster, PT G1/8 port, and your required mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the stroke is 280 mm, the 12 mm rod and M10x1.25 thread will experience greater leverage forces under side loads; an external guide rail is recommended to prevent rod binding. Remember that the SAIJ rear adjuster and air cushions only set the travel end and decelerate the load—they do not hold the cylinder in place without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series.

- ✓ 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 SAIJ32BX280-50 FAQ
The rear adjuster screw acts as an external stopper that can shorten the nominal 280 mm stroke by up to 50 mm, giving you an effective 230-280 mm travel window. It allows fine-tuning of the retract end-position at commissioning without changing the cylinder itself.
At 0.5 MPa, the SAIJ32X280-50 provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
