Airtac SAIJ50 Adjustable Cylinder SAIJ50AX500-100
The AirTAC Airtac SAIJ50 Adjustable Cylinder SAIJ50AX500-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 500mm 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 SAIJ50AX500-100
The AirTAC SAIJ50X500-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 400-500 mm usable travel window, allowing you to dial back the nominal 500 mm stroke by up to 100 mm during commissioning. This bore delivers 982 N of push force and 825 N of pull force at 0.5 MPa, making it a robust choice for moderate linear actuation.
Equipped with a SUS420J2 stainless steel rod (material code A) and PT tapered port threads, it handles demanding environments better than standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster functions strictly as a travel stop for end-position tuning, not as a lock; for load-holding without live air pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX500-100 Is Used
Product Changeover
Quickly adapt packaging line stroke length for different carton sizes using the 100 mm adjustment range instead of replacing the entire cylinder assembly.
End-Stop Calibration
Fine-tune the final retract position during machine commissioning to achieve precise seating without adding bulky external mechanical stops.
Variable Sorting
Adjust the pusher travel window from 400 to 500 mm on the fly to accommodate varying product lengths on a conveyor sorting system.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX500-100 the Right Cylinder?
Choose this 50 mm bore adjustable-stroke cylinder when your machine setup requires variable end stops or product-size changeovers without swapping the physical actuator. If you need less force, stepping down to a 40 mm bore yields 628 N push at 0.5 MPa, while stepping up to a 63 mm bore provides 1559 N. Because the nominal stroke is 500 mm, the M16x1.5 rod and 20 mm diameter face side-load risks over long unsupported distances; always guide the load externally to prevent premature seal wear.
This model uses a reduced mounting interface set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. It is dimensionally interchangeable with ISO 15552 cylinders. Since no magnet is specified, it will not work with CMSE reed or DMSE electronic sensors without modification.

- ✓ 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 SAIJ50 Adjustable Cylinder SAIJ50AX500-100 FAQ
The rear adjuster screw lets you shorten the effective travel by up to 100 mm, creating a 400-500 mm usable window. It acts as a mechanical stop to tune the end position, but it does not lock the load without live air pressure.
At 0.5 MPa operating pressure, it provides 982 N of push force and 825 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 1767 N.
