About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-30S
The AirTAC SAIJ160X45-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 45 mm travel to a highly precise 15 to 45 mm usable window. In the 160 mm bore class, it generates 14074 N of push force and 9425 N of pull force at 0.7 MPa, making it well suited for heavy-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The rear adjustment mechanism acts strictly as a mechanical stop to fine-tune the end position at commissioning without requiring external stops. Remember that this adjuster is not a lock; the cylinder cannot hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-30S Is Used
Heavy Press Tuning
Dial in the exact 15 to 45 mm travel window during heavy press commissioning to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the retract end-stop on automated assembly lines when switching between product sizes, saving downtime on physical mechanical modifications.
Corrosive Forming
Leverage the SUS304 stainless steel rod in high-humidity or washdown manufacturing environments while utilizing DMSE solid-state sensors for position feedback.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX45-30S the Right Cylinder?
Select this 160 mm bore adjustable-stroke cylinder when your application requires exact end-position tuning during machine setup or product changeover, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your process demands less force, stepping down to a 125 mm bore yields 8590 N of push at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991 N.
For a true ISO 15552 replacement, match the 160 mm bore, 45 mm stroke, 30 mm adjustment range, PT tapered port threads, and the -S magnet option. This profile cylinder supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300 mm, side-load concerns are minimal, but always ensure the load is guided to prevent binding.
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 SAIJ160BX45-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It operates at speeds between 30 and 500 mm/s.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 45 mm down to as little as 15 mm. It is used for fine-tuning end positions at commissioning but does not lock or hold the load without continuous air pressure.
