Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-50S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 950mm 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 SAIJ160BX950-50S
The AirTAC SAIJ160X950-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end-position within a 900 to 950 mm travel window without adding external stops. It delivers robust thrust, generating 14074 N of push force and 9425 N of pull force at a 0.7 MPa operating pressure. This non-standard 950 mm stroke is built to order but remains well within the 1500 mm maximum standard stroke limit for this bore size.
Equipped with a SUS304 stainless steel rod (option B) and a PT tapered port thread, this unit is tailored for harsher environments. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop to decelerate the load, so it does not hold position without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-50S Is Used
Large Press Setup
Dial in the exact 900-950 mm retract position during heavy press commissioning without swapping out the cylinder.
Product Size Changeover
Adapt the stroke end-stop on automated lines quickly when handling different sizes of large bulk materials.
Heavy Material Handling
Move substantial loads using 14074 N of thrust at 0.7 MPa while relying on the external guide for stability.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-50S the Right Cylinder?
Choose this 160 mm bore when a 125 mm bore falls short, as the smaller neighbor only provides 8590 N of push force at 0.5 MPa compared to this bore's 10053 N. An adjustable-stroke cylinder is selected over a fixed SAI model when you need precise end-position tuning during commissioning or product changeover. To replace this cylinder with an equivalent ISO 15552 dimensionally interchangeable unit, match the 160 mm bore, 950 mm stroke, 50 mm adjustment, PT port, and the -S magnet requirement.
Because the 950 mm stroke is long and unsupported, the 40 mm rod diameter and M36x2 thread will carry significant side-load stress, making an external guide rail essential to prevent premature wear. For applications that must hold a load without continuous live air, pair this cylinder with an external rod lock or select the SAIL or BSAI clamp-lock series instead.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX950-50S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw lets you shorten the effective travel from the 950 mm nominal stroke by up to 50 mm, providing a usable 900-950 mm window. This stopper decelerates the load at the end of travel but does not lock the position without live air pressure.
