About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-30S
The AirTAC SAIJ160X650-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a massive 18095N push force at 0.9 MPa. It features a 650mm nominal stroke that can be fine-tuned down by up to 30mm, creating a precise 620-650mm usable travel window. This adjustability allows you to dial in exact end positions during commissioning without swapping hardware.
Built with a SUS304 stainless steel rod and a PT tapered port, this unit includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear stopper acts purely as a travel limit, meaning it will not hold a load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-30S Is Used
Heavy Press Tuning
Fine-tune the 620-650mm travel window during setup to precisely control heavy pressing operations without machining custom spacers.
Product Changeovers
Quickly adjust the end-stop position by up to 30mm on packaging lines to accommodate different carton sizes on the fly.
Large Assembly Jigs
Leverage the 18095N push force to move heavy fixtures, using the rear screw to perfectly seat components at the end of the stroke.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-30S the Right Cylinder?
Choose this 160mm bore when an 80mm cylinder (providing 4523N push at 0.9 MPa) lacks the thrust for heavy positioning tasks. The adjustable 620-650mm window is perfect for machines processing varying product sizes, eliminating the need for external stops. If your application requires true load-holding without air pressure, step over to the SAIL or BSAI series, as the SAIJ adjuster is a stop, not a clamp lock.
For a direct ISO 15552 replacement, match the 160mm bore, 650mm stroke, 30mm adjustment, PT port, and -S magnet. Because the 650mm stroke is long and unsupported, the 40mm rod and M36x2 thread still require an external guide to prevent excessive side-loading. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX650-30S FAQ
At 0.9 MPa, this 160mm bore cylinder generates 18095N of push force and 15080N of pull force. It reaches a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 650mm nominal stroke by up to 30mm, providing a usable travel range of 620-650mm. This stopper only limits travel and does not lock the load without live air.
