About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-50S
The AirTAC SAIJ160X80-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 30 to 80 mm from its 80 mm nominal stroke, allowing precise end-position tuning without swapping physical hardware. Belonging to the 160 mm bore class, it delivers substantial thrust, pushing 18095 N at 0.9 MPa. This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a -S magnet for position detection.
The rear adjustment mechanism acts purely as a mechanical stop to trim the retract stroke, meaning it will not hold a load without live air pressure. For load-holding applications, a SAIL or BSAI series cylinder is required. This extruded aluminum profile cylinder omits the FB, CA, CB, and CR mounting styles, supporting only the Basic, FA, LB, TC, FTC, TCM1, and TCM2 interface options. The dual-sided sensor grooves accommodate CMSE reed and DMSE electronic switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-50S Is Used
Press Fit Tuning
Dial in the exact 30 to 80 mm insertion depth for heavy-duty press fits during machine setup, ensuring perfect assembly without changing cylinders.
Product Changeover
Quickly adjust the retract end-stop on a packaging line when switching to a different product size, using the rear screw to modify the travel window instantly.
Position Verification
Leverage the built-in -S magnet with DMSE electronic sensors to confirm end-of-stroke positioning while fine-tuning the mechanical stop for commissioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-50S the Right Cylinder?
Choose this 160 mm bore if your application requires heavy thrust, such as pushing 14074 N at 0.7 MPa, but stepping down to the 125 mm bore (8590 N at 0.5 MPa) is preferable for lighter, faster tasks. The adjustable 50 mm trim is ideal for product changeovers, letting you dial in the exact end-stop on the fly instead of installing a fixed-stroke SAI cylinder. When ordering an ISO 15552 replacement, match the 160 mm bore, 80 mm stroke, PT tapered ports, -S magnet, and SUS304 rod material. Because the stroke is under 300 mm, side-load stress on the M36x2 rod thread is manageable, though external guidance is recommended for heavy radial loads.
Quick checklist
- ✓ 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 SAIJ160BX80-50S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. It achieves a maximum push force of 2050 kgf at 1.0 MPa.
The rear adjuster screw lets you mechanically shorten the 80 mm nominal stroke by up to 50 mm, creating a usable travel window of 30 to 80 mm. This stop only sets the end position; it does not lock the load without live air pressure.
