About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-100
The AirTAC SAIJ160X450-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 350 to 450 mm, allowing you to dial back the nominal stroke by up to 100 mm. This bore size generates a substantial 10053 N of push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific unit ships without a magnet. You can fine-tune the retract end-position directly at commissioning without adding external stops.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-100 Is Used
Heavy Press Tonnage
Delivers 18095 N of push force at 0.9 MPa for heavy assembly and pressing operations requiring precise end-stop control.
Machine Changeover
The 350-450 mm travel window allows operators to quickly adapt machinery for different product sizes without swapping cylinders.
Large Material Handling
Moves substantial payloads with a 40 mm rod and G3/4 PT port, handling high flow rates for rapid cycling at 30-500 mm/s.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-100 the Right Cylinder?
Choose this 160 mm bore when 100 mm bore's 3927 N at 0.5 MPa is insufficient, but the 200 mm bore's 15708 N is excessive. The 100 mm adjustment range is ideal for machinery requiring significant setup flexibility or product-size changeovers. Because the stroke is 450 mm, the 40 mm rod diameter should be paired with an external guide to prevent excessive side-loading on the piston.
The rear adjuster acts as a travel stop to set the end position, not a lock. It will not hold a load without live air pressure. For drop-prevention, consider the SAIL (lock) or BSAI (clamp-lock) series. This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: 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 SAIJ160BX450-100 FAQ
At 0.5 MPa, the 160 mm bore provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster lets you shorten the effective travel from 450 mm down to 350 mm. It acts as a mechanical stop for end-position tuning at commissioning, but it is not a lock and requires live air to hold the load.
