About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-75S
The AirTAC SAIJ160X500-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 500 mm nominal stroke by up to 75 mm. This yields a 425-500 mm usable travel window, providing fine end-position tuning at commissioning without swapping the barrel or adding external stops. The 40 mm SUS304 stainless steel rod and M36x2 thread handle high side loads, while the PT tapered ports seal securely.
Delivering 14074 N of pull force at 0.7 MPa, this heavy-duty actuator features an extruded aluminum barrel with sensor grooves on both sides. It includes a magnet for CMSE reed and DMSE electronic sensors, enabling precise position feedback. The rear adjuster acts purely as a travel stop for deceleration; it does not hold the load without live air, so use a SAIL or BSAI lock for fail-safe holding.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-75S Is Used
Press Tonnage Calibration
Dial in the exact 425-500 mm end-of-stroke position during press setup to accommodate varying material thicknesses without repositioning the entire fixture.
Product Size Changeover
Adjust the retract stop up to 75 mm on packaging lines when switching to a different pallet or container size, minimizing downtime between production runs.
Heavy Material Ejection
Leverage the 14074 N pull force at 0.7 MPa to reliably eject heavy molded parts from machinery, using the adjustable stop to time the ejection point accurately.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-75S the Right Cylinder?
Choose this 160 mm bore when an application requires substantial thrust, such as 18095 N pull at 0.9 MPa, but stepping down to the 125 mm bore yields only 11045 N. The 75 mm adjustment range is ideal for product-size changeovers on a line, letting operators set variable end-stops quickly. If you need pure fixed travel without a rear screw, the standard SAI series is simpler, but this SAIJ variant excels when mechanical fine-tuning is required during setup.
For ISO 15552 replacement matching, specify the 160 mm bore, 500 mm stroke, 75 mm adjustment, PT port thread, and the -S magnet. Because the stroke is 500 mm, the long unsupported rod is susceptible to deflection; always guide the load externally to prevent binding. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

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 SAIJ160BX500-75S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm, creating a 425-500 mm travel window. It acts as a mechanical stop to fine-tune the end position and works with the built-in air cushion for deceleration, but it does not lock or hold the load without continuous air pressure.
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 14074 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 18095 N of pull force.
