Airtac SAIJ50 Adjustable Cylinder SAIJ50BX350-100S
The AirTAC Airtac SAIJ50 Adjustable Cylinder SAIJ50BX350-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 350mm stroke, G1/4 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 SAIJ50 Adjustable Cylinder SAIJ50BX350-100S
The AirTAC SAIJ50X350-100-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering 982N of push force at 0.5MPa. It features a 250-350mm usable travel window, allowing you to dial back the 350mm nominal stroke by up to 100mm. The SUS304 stainless steel rod offers superior corrosion resistance, and the integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic sensors.
This model uses a PT tapered G1/4 port and includes variable air cushions at both ends to decelerate the load. The rear adjuster acts purely as a travel stop for end-position tuning and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX350-100S Is Used
Machine Changeover
Dial in the 250-350mm travel window during product size changes without physically replacing the cylinder or bolting on external stops.
Variable End Stops
Sort or divert packages on a line by adjusting the retract end-position up to 100mm to accommodate different carton lengths on the fly.
Fixture Clamping
Fine-tune the clamping reach on multi-part fixtures, using the SUS304 rod for corrosion resistance in environments with coolant or washdowns.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX350-100S the Right Cylinder?
Choose this 50mm bore when your application requires 982N push force at 0.5MPa, stepping up from the 40mm bore that provides 628N. The 100mm adjustment range is ideal for product changeovers, letting you fine-tune the end position at commissioning without swapping cylinders or adding external stops. Since the stroke is 350mm, an external guide is recommended to prevent excessive side loading on the rod thread.
This SAIJ50X350-100-S is dimensionally interchangeable per ISO 15552 mounting interface dimensions. It supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The PT port thread and -S magnet configuration must be specified to match your setup exactly.

- ✓ 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 SAIJ50 Adjustable Cylinder SAIJ50BX350-100S FAQ
At 0.5MPa operating pressure, this 50mm bore cylinder provides 982N of push force and 825N of pull force. At the maximum 1.0MPa pressure, it delivers up to 200kgf.
The rear adjuster screw lets you shorten the effective stroke from the nominal 350mm down to 250mm. This creates a 250-350mm usable travel window for fine-tuning end positions at commissioning. The adjuster is a stop, not a lock, and requires live air to hold the load.
