About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-10
The AirTAC SAIJ160X85-10 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to fine-tune the retract end position. It provides a usable travel window of 75 to 85 mm, letting you dial back the nominal 85 mm stroke by up to 10 mm without adding external stops. Built with an extruded aluminum barrel, it is dimensionally interchangeable per ISO 15552 standards.
This bore size delivers substantial thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa. The piston rod is constructed from SUS304 stainless steel (code B) for superior corrosion resistance, and the PT tapered port threads match the G3/4 air supply requirement. It features variable air cushions at both ends to decelerate heavy loads smoothly within its 30 to 500 mm/s operating speed range.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-10 Is Used
Heavy Press Tuning
Dial in the exact 75 to 85 mm pressing depth during commissioning to accommodate material thickness variations without swapping physical components.
Product Changeover
Quickly adjust the retract end-stop by up to 10 mm on a packaging line to handle slightly different pallet or product sizes on the fly.
High-Force Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy jigs into place, relying on the rear stopper for precise final positioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-10 the Right Cylinder?
Selecting this 160 mm bore makes sense when your application requires high force, as it outputs 10053 N of push force even at a conservative 0.5 MPa. If you need less force, stepping down to a 125 mm bore drops the 0.5 MPa push force to 6136 N. The 10 mm adjustment range is ideal for precise machine setup and product changeovers, offering exact end-position tuning that a fixed-stroke SAI cylinder cannot provide.
When matching this for an ISO 15552 replacement, verify the 85 mm stroke, 10 mm adjustment, PT port thread, and SUS304 rod material. Note that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither will hold a load without live air pressure. For positive load-holding, consider an AirTAC SAIL or BSAI cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ160BX85-10 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. At 0.5 MPa, the push force is 10053 N.
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a usable travel window of 75 to 85 mm. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
