About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-75
The AirTAC SAIJ160X500-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits you to dial back the retract end by up to 75 mm. This yields a usable travel window between 425 and 500 mm, enabling exact end-position tuning at commissioning without adding external stops. It delivers substantial thrust, pushing with 14074 N and pulling with 9425 N at 0.7 MPa, making it suited for heavy-duty positioning tasks.
This SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for straightforward detection integration. Remember that the rear adjuster acts purely as a travel stop to set deceleration; it does not lock the load. For true position holding without live air pressure, consider the related SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-75 Is Used
Heavy Press Fine-Tuning
Dial in the exact 425-500 mm end position during machine commissioning to accommodate varying material thicknesses without replacing the entire cylinder.
Product Size Changeovers
Quickly adjust the retract stop on a packaging line to handle different product lengths, utilizing the 75 mm adjustment range for rapid format changes.
Large Fixture Positioning
Position heavy manufacturing fixtures with 14074 N of thrust at 0.7 MPa, relying on the rear stopper to set the precise retraction point.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX500-75 the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high force—delivering 14074 N of push force at 0.7 MPa—and a variable retract end-stop. If you require less force and a more compact footprint, stepping down to the 125 mm bore yields 8590 N of push force. Conversely, if your application needs even greater thrust, the 200 mm bore provides 21991 N. The adjustable 425-500 mm window is ideal for product changeovers on a line, allowing you to fine-tune the stroke on the fly rather than swapping out a fixed-stroke SAI cylinder.
Because this unit features a 500 mm stroke, the long unsupported rod length necessitates an external guide to prevent excessive side-loading and premature seal wear. The robust M36x2 rod thread handles heavy loads, but external guidance remains critical. This cylinder uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. It operates at speeds of 30-500 mm/s.

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 SAIJ160BX500-75 FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke by up to 75 mm. For a 500 mm nominal stroke, this creates an adjustable travel window of 425 to 500 mm, allowing you to fine-tune the end position without swapping the cylinder.
At an operating pressure of 0.7 MPa, this 160 mm bore double-acting cylinder generates a push (extend) force of 14074 N and a pull (retract) force of 9425 N. The maximum push force is 18095 N at 0.9 MPa.
