Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-40S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 200mm 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 SAIJ160X200-40S
The AirTAC SAIJ160X200-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 160 to 200 mm window. Delivering 14074 N of push force at 0.7 MPa, it handles heavy-duty positioning with precision. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for position detection.
This model uses a robust 40 mm carbon steel rod with an M36x2 thread, providing high rigidity against side loads. The rear adjuster acts purely as a travel stop for end-position tuning during commissioning; it is not a locking device and will not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-40S Is Used
Heavy Press Tuning
Dial in the exact bottoming position of a heavy press during tooling changes, using the 40 mm adjustment window to compensate for material thickness variations.
Product Diversion
Adjust the retract distance of a heavy-duty diverter arm on a conveyor line to accommodate different package sizes without changing the cylinder.
Machine Changeover
Rapidly reset the end-stop on automated assembly machinery during product line changeovers, saving time by avoiding mechanical cylinder swaps.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-40S the Right Cylinder?
Choose this 160 mm bore when your application requires over 14000 N of thrust at 0.7 MPa and you need to dial in the exact end-stop without adding external bumpers. If your force requirements are lower, stepping down to a 125 mm bore yields 8590 N of push force at 0.7 MPa, which may offer a more compact footprint. Conversely, if you need maximum thrust, the 200 mm bore provides 21991 N at 0.7 MPa.
An adjustable stroke is ideal for machine setups that undergo frequent product changeovers, allowing the end position to be trimmed by up to 40 mm rather than swapping out a fixed-stroke SAI cylinder. This specific configuration includes PT tapered ports, a standard carbon steel rod, and a -S magnet for use with AirTAC CMSE reed and DMSE electronic sensors. Because the total stroke reaches 200 mm, ensure proper external guidance to prevent rod binding under offset loads. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

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 SAIJ160X200-40S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke from its nominal 200 mm down to 160 mm. This creates a 160-200 mm usable travel window for fine-tuning the end position at commissioning, but it functions only as a stop and does not lock the load without air pressure.
