About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-50S
The AirTAC SAIJ160X280-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 230 to 280 mm for fine-tuning end positions. Built with a 160 mm bore, it delivers substantial thrust, pulling 9425 N at 0.5 MPa and pushing 18095 N at 0.9 MPa. The extruded aluminum barrel features sensor grooves on both sides, and this variant includes a magnet for position detection.
This model utilizes a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered ports. The rear adjustment mechanism acts strictly as a travel stop to dial in the retract distance during commissioning or product changeovers without swapping the cylinder. It is important to note that this adjuster and the variable air cushions at both ends decelerate the load but do not hold it without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-50S Is Used
Heavy Press Fine-Tuning
Dial in the exact end-stop during heavy press commissioning over a 230 to 280 mm window without adding external stopper blocks.
Product Changeover
Quickly adjust the retract position on a packaging line to handle different product sizes using the 50 mm rear adjuster.
Automated Assembly
Leverage the 18095 N push force at 0.9 MPa to seat heavy components while using the variable end-stop for precise alignment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-50S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires heavy force combined with variable end-stops, stepping up from a 125 mm bore that yields 5734 N pull at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring precise positioning over a 230 to 280 mm window, whereas a fixed SAI cylinder locks you into a single 280 mm dimension. For load-holding without continuous air pressure, this plain SAIJ is insufficient; consider an SAIL air-released lock, a BSAI clamp-lock, or an external rod lock.
As a dimensionally interchangeable per ISO 15552 cylinder, this SKU matches the standard 160 mm bore, 280 mm stroke, 50 mm adjustment, PT ports, and Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting options (omitting FB, CA, CB, and CR). The included -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors. Given the 280 mm stroke and 40 mm rod diameter, long unsupported strokes still require an external guide to manage side loads.

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 SAIJ160BX280-50S FAQ
This 160 mm bore cylinder delivers a push force of 14074 N at 0.7 MPa and 18095 N at 0.9 MPa. The pull force is 9425 N at 0.5 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 280 mm down to 230 mm. It sets the end position but does not lock the load without live air pressure.
