Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-40S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 195mm 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 SAIJ160X195-40S
The AirTAC SAIJ160X195-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 155-195 mm window without adding external stops. In the 160 mm bore class, it generates a substantial 14074 N push force at 0.7 MPa, making it well-suited for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for direct compatibility with CMSE reed and DMSE electronic solid-state switches.
This model uses a robust 40 mm diameter carbon steel rod with an M36x2 thread, providing excellent rigidity against side loads, though long unsupported strokes still require an external guide. The rear adjuster acts strictly as a mechanical stop to set the retract end-position and pairs with variable air cushions at both ends for deceleration; it is not a locking mechanism and cannot hold a load without live air pressure. For load-holding without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-40S Is Used
Heavy Machinery Changeover
Dial in the 155-195 mm retract stroke during product size changes on heavy machinery without replacing the cylinder or bolting on external stopper blocks.
Press Positioning
Leverage the 14074 N push force at 0.7 MPa to seat heavy components, using the rear adjuster to fine-tune the final contact position precisely.
Automated Assembly Tuning
Adjust the end-stop during commissioning of large automated assembly lines, using the integrated magnet with DMSE electronic sensors for precise position verification.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-40S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires high thrust (up to 18095 N at 0.9 MPa) combined with a variable end-stop for product changeovers. If you need less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, while moving up to a 200 mm bore provides 21991 N at 0.7 MPa. The 40 mm adjustment range is ideal for dialing in precise retract positions at commissioning without swapping the cylinder body.
To replace an ISO 15552 cylinder, match the 160 mm bore, 195 mm stroke, 40 mm adjustment, PT tapered port threads, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR mounts. Because the stroke approaches 195 mm, ensure your mounting configuration supports the rod adequately to prevent binding.

- ✓ 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 SAIJ160X195-40S FAQ
At 0.7 MPa, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. At its maximum operating pressure of 1.0 MPa, it achieves a push force of 18095 N.
The rear adjusting screw allows you to shorten the effective 195 mm stroke by up to 40 mm, creating a usable travel window of 155-195 mm. This mechanical stop fine-tunes the retract end position at commissioning but does not lock or hold the load without live air pressure.
