About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-50
The AirTAC SAIJ160X850-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the retract position. Based on an 850 mm nominal stroke, the external stopper screw provides a 50 mm adjustment range, creating a usable travel window between 800 and 850 mm. This enables precise end-position calibration during commissioning without adding external stops.
Delivering substantial thrust, this 160 mm bore unit generates 18095 N of push force at 0.9 MPa. It features a SUS304 stainless steel rod for corrosion resistance and utilizes a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, while the generous 50 mm cushioning at both ends manages the deceleration of heavy moving loads.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-50 Is Used
Press Tonnage Setup
Adjust the 800-850 mm travel window to set precise lower-die positions during machine commissioning or when changing die heights.
Variable Length Diverter
Tune the retract stop point on the fly to accommodate different package lengths on a sorting line without changing cylinders.
Heavy Assembly Station
Dial in the exact 850 mm end-position to push large components into fixtures, relying on the 18095 N push force for secure seating.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX850-50 the Right Cylinder?
Choose this adjustable-stroke model when an application requires variable end-stops or frequent product changeovers, as the rear adjuster allows rapid recalibration without swapping out a fixed-stroke SAI cylinder. If your process demands less force, stepping down to a 125 mm bore yields 11045 N of push force at 0.9 MPa. Because this is a long 850 mm stroke, the 40 mm rod diameter and M36x2 thread provide rigidity, but an external guide is still recommended to prevent side-loading damage.
This SAIJ configuration uses a PT tapered port and lacks a magnet for sensors. The rear adjuster acts purely as a mechanical travel stop to set deceleration, not as a lock; it will not hold a load without live air pressure. For true load-holding without continuous air, consider an SAIL or BSAI cylinder. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles.

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 SAIJ160BX850-50 FAQ
The rear adjuster screw lets you mechanically shorten the effective travel. For this model, you can trim the 850 mm nominal stroke back by up to 50 mm, providing an 800 to 850 mm usable window for exact end-position tuning.
At an operating pressure of 0.9 MPa, the SAIJ160X850-50 generates a push force of 18095 N and a pull force of 9425 N.
