About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-75
The AirTAC SAIJ160X115-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning. With a nominal 115 mm stroke and a 75 mm adjustment code, the effective travel window can be dialed back anywhere from 115 mm down to 40 mm. This wide usable range allows operators to accommodate multiple product sizes on a single line without physically swapping the actuator or adding external mechanical stops.
Belonging to the 160 mm bore class, this heavy-duty unit delivers a substantial 14074 N of push force at 0.7 MPa and utilizes a robust 40 mm carbon steel piston rod with an M36x2 thread. It features a PT tapered port, dual-sided sensor grooves for mounting standard switches, and variable air cushions at both ends to manage deceleration. The extruded aluminum barrel design maintains strict ISO 15552 mounting-interface interchangeability while avoiding the bulk of traditional tie-rod cylinders.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-75 Is Used
Variable Format Changeovers
Quickly dial in the exact end-position from 40 to 115 mm during product size transitions on large machinery without disassembling the pneumatic circuit.
Heavy Pressing Operations
Leverage the 14074 N push force at 0.7 MPa for heavy-duty pressing or forming tasks, fine-tuning the travel limit to accommodate different material thicknesses.
Prototyping and R&D Fixtures
Ideal for test rigs where the optimal stroke distance is unknown, allowing engineers to set and lock the rear stopper at various points within the 75 mm adjustment range.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-75 the Right Cylinder?
Choose this 160 mm bore actuator when an application demands high thrust combined with variable end-stops, such as format changeovers on large packaging equipment. If the 10045 N push force at 0.5 MPa is excessive for your fixture, stepping down to the 125 mm bore yields 6136 N at the same pressure while preserving the ISO 15552 footprint. Conversely, moving up to the 200 mm bore provides 21991 N at 0.7 MPa for extreme load requirements.
Because this model carries a 115 mm stroke, the integrated rear adjuster provides a massive 75 mm trim window, making it highly effective for prototyping or varying part lengths on the fly. Remember that the rear adjuster acts strictly as a travel stop and does not lock the load; for position holding without live air pressure, consider an AirTAC SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 160 mm bore, 115 mm stroke, PT port, and required mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).

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 SAIJ160X115-75 FAQ
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke from 115 mm down to 40 mm. It allows fine-tuning of the end-position during commissioning without swapping the cylinder, though it does not hold the load without live air pressure.
At 0.7 MPa operating pressure, the SAIJ160X115-75 generates 14074 N of push force and 9425 N of pull force. It can deliver up to 18095 N of push force at its maximum rated pressure of 0.9 MPa.
