About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-100S
The AirTAC SAIJ160X500-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 10053N push force at 0.5 MPa, featuring a 40 mm stainless steel SUS304 rod and a PT G3/4 port. By integrating a 100 mm adjustment mechanism at the rear cap, this model creates a usable travel window between 400 and 500 mm, allowing technicians to dial in the exact retract position during commissioning without swapping out the physical cylinder.
This heavy-duty actuator incorporates an extruded aluminum barrel with sensor grooves on both sides, designed specifically to house CMSE reed and DMSE electronic switches for precise end-position feedback. The rear stopper screw acts purely as a travel end-limit and deceleration point, meaning it cannot hold a load without continuous live air pressure. For applications requiring true load-holding upon air loss, you should explore the SAIL pneumatic lock or BSAI clamp-lock series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-100S Is Used
Heavy Press Tonnage
Delivers 10053N of thrust at 0.5 MPa for forming and stamping rigid materials where high force is non-negotiable.
Pallet Size Changeover
The 100 mm rear adjuster shortens the travel window down to 400 mm, allowing a single actuator to handle variable pallet depths without hardware swaps.
Washdown Assembly
The SUS304 stainless steel rod provides the corrosion resistance needed for food processing or washdown environments while retaining ISO 15552 dimensions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-100S the Right Cylinder?
Selecting this 160 mm bore over a 125 mm unit steps the thrust up from 6136N to 10053N at 0.5 MPa, while moving to a 200 mm bore would push that figure to 15708N. The 100 mm adjustment range is ideal for large-scale product changeovers where the effective stroke needs to be shortened significantly, offering a 400-500 mm window that prevents the need for external mechanical stops. Because the nominal stroke is 500 mm, the 40 mm SUS304 rod will experience leverage forces under load, so an external guide carriage is strongly recommended to prevent side-loading damage.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 500 mm stroke, PT G3/4 port, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This unit includes the -S magnet for CMSE / DMSE sensors and utilizes a SUS304 stainless steel rod for superior corrosion resistance.

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 SAIJ160BX500-100S FAQ
At a 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053N of push force and 9425N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The nominal stroke is 500 mm, but the rear adjuster allows you to trim the travel back by up to 100 mm. This creates a usable stroke window between 400 and 500 mm, enabling fine-tuning of the retract end position without changing the cylinder.
