Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-30
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 80mm 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 SAIJ160BX80-30
The AirTAC SAIJ160X80-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel down to a 50-80 mm window without swapping hardware. Built with a SUS304 stainless steel rod, it delivers 14074 N of push force at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides, though this specific unit ships without a magnet for electronic positioning.
By turning the rear stopper screw, you can dial in the exact end position during machine commissioning or product changeovers. This adjuster acts strictly as a travel stop and works alongside the standard 50 mm air cushions to decelerate the load, but it will not hold the load without live air pressure. For load-holding requirements, consider an external rod lock or the AirTAC SAIL series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-30 Is Used
Product Changeovers
Quickly adjust the 50-80 mm travel window on packaging lines to accommodate different carton or product sizes without changing the cylinder.
End-Position Tuning
Fine-tune the retraction end-stop during machine commissioning to achieve exact clamping or pressing positions on heavy assemblies.
Heavy Forming Presses
Leverage the 14074 N push force at 0.7 MPa for short-stroke pressing operations, using the rear stopper to set precise forming depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-30 the Right Cylinder?
Choose this 160 mm bore when you need substantial thrust—14074 N push at 0.7 MPa—within a compact 80 mm stroke that can be precisely trimmed by up to 30 mm. If your application requires less force, stepping down to a 125 mm bore yields 8590 N push at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991 N. The adjustable end-stop is ideal for setups requiring variable end positions, offering more flexibility than a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 80 mm nominal stroke, PT tapered port threads, and the specific 30 mm adjustment code. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Although the stroke is short, the 40 mm rod diameter and M36x2 thread provide excellent side-load resistance for heavy tooling.
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 SAIJ160BX80-30 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At a maximum 1.0 MPa, the push force reaches 18095 N.
The rear adjuster screw allows you to shorten the 80 mm nominal stroke by up to 30 mm, creating a usable travel window of 50-80 mm. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
