Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-100S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 650mm stroke, G3/4 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 SAIJ160 Adjustable Cylinder SAIJ160BX650-100S
The AirTAC SAIJ160X650-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 650 mm travel by up to 100 mm. This creates a precise 550-650 mm usable window, allowing exact end-position tuning at commissioning without swapping the barrel or adding external stops. It features a SUS304 stainless steel rod and a PT tapered port thread.
Belonging to the 160 mm bore class, it delivers substantial thrust, pushing 18095 N at 0.9 MPa. The extruded aluminum profile includes sensor grooves on both sides, and because this unit includes a magnet (-S), it supports AirTAC CMSE reed and DMSE electronic switches for position feedback. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-100S Is Used
Machine Changeover
Dial in the 550-650 mm travel window during product size changes on a line without physically replacing the actuator.
Long-Stroke Pressing
Leverage the 18095 N push force at 0.9 MPa for heavy pressing, using the rear stopper to set exact material contact depth.
Variable End-Stop Setup
Use the 100 mm adjustment range to fine-tune the retract position during machine commissioning, avoiding external stop hardware.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-100S the Right Cylinder?
Choose this 160 mm bore cylinder when an application demands high force combined with variable end stops for product changeover. If you need less thrust, stepping down to a 125 mm bore yields 11045 N of push force at 0.9 MPa. Because the stroke is 650 mm, the M36x2 rod thread and 40 mm rod diameter provide rigidity, but an external guide is recommended to prevent side-load damage over this long unsupported travel.
The adjustable rear screw is ideal for fine-tuning deceleration at the travel end, but remember it is a stop, not a lock. For load-holding without live pressure, select an SAIL air-released lock or BSAI clamp-lock cylinder. To match this ISO 15552 footprint, specify the 160 mm bore, 650 mm stroke, 100 mm adjustment, PT G3/4 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX650-100S FAQ
The rear adjuster allows you to shorten the 650 mm nominal stroke by up to 100 mm, creating a 550-650 mm usable travel window. It functions as a mechanical stop to tune the end position and does not lock the load without live air.
At 0.9 MPa, the push force is 18095 N and the pull force is 9425 N. At 0.5 MPa, it provides 10053 N of push force.
