About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-50S
The AirTAC SAIJ160X260-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 260 mm travel by up to 50 mm. This creates a precise 210-260 mm usable window for fine-tuning the retract end position during commissioning without swapping out the barrel. It delivers a substantial 14074 N push force at 0.7 MPa, matching the standard SAI thrust class for heavy-duty tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel carries sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical stop for end-position tuning; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-50S Is Used
Machine Changeover
Dial in the exact retract position within the 210-260 mm window during product size changes without replacing the cylinder.
Heavy Pressing
Leverage 14074 N of push force at 0.7 MPa for heavy assembly operations while fine-tuning the end stop.
Position Sensing
Utilize the integrated magnet with DMSE solid-state sensors for precise position feedback in automated lines.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX260-50S the Right Cylinder?
Choose this 160 mm bore when an application demands high thrust—delivering 10053 N push at 0.5 MPa—stepping up from a 125 mm bore that yields 6136 N, or down from a 200 mm bore providing 15708 N. The adjustable stroke is ideal for product changeovers where the exact retract distance varies, offering a built-in external stop instead of requiring fixed-stroke SAI cylinders. For load-holding without continuous air pressure, this cylinder is insufficient; the rear stop is not a brake, so you must integrate a SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock.
To match this ISO 15552 replacement, specify a 160 mm bore, 260 mm stroke, 50 mm adjustment range, PT tapered ports, and the -S magnet option. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 260 mm stroke is relatively long, ensure external guide rails are used to support the load and prevent excessive side-loading on the M36x2 rod thread.

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 SAIJ160BX260-50S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can deliver up to 10053 N push at 0.5 MPa.
The rear adjuster screw lets you shorten the 260 mm nominal stroke by up to 50 mm, providing a usable travel window of 210 to 260 mm. This allows you to set the exact retract end position during commissioning without adding external stops.
