About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-100
The AirTAC SAIJ160X125-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 10053N push force at 0.5 MPa. Its extruded aluminum barrel features sensor grooves on both sides, and it operates efficiently at speeds between 30-500 mm/s. This heavy-duty actuator uses a PT tapered port thread and a carbon steel piston rod.
With a 125mm nominal stroke and a 100mm adjustment range, this model provides a highly versatile 25-125mm usable travel window. The rear screw mechanism allows operators to dial in the exact retract end-position during commissioning without swapping hardware. Remember that this rear stopper only sets the travel limit and decelerates the load via the variable air cushion; it does not function as a lock, so live air is required to hold the load in place.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-100 Is Used
Heavy Machinery Setup
Fine-tune the 25-125mm retract position during heavy equipment commissioning to achieve precise alignment without machining custom spacer blocks.
Product Size Changeovers
Quickly adapt automated pressing stations to different material thicknesses by dialing the rear stopper, maximizing line flexibility.
Variable End-Stop Forming
Leverage the 10053N thrust for metal-forming tasks that require adjustable depth limits within a 25-125mm travel window across production runs.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X125-100 the Right Cylinder?
Choose this 160mm bore actuator when an application demands high thrust combined with variable end-stop positioning, such as accommodating multiple product sizes on a single line. If the 10053N push force at 0.5 MPa exceeds your requirements, stepping down to a 125mm bore yields 6136N; conversely, moving up to a 200mm bore provides 15708N. For fixed-position tasks without the need for end-tuning, the standard SAI cylinder is a simpler alternative.
When replacing an ISO 15552 cylinder, match the 160mm bore, 125mm stroke, PT port thread, and carbon steel rod. This SAIJ model supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 40mm rod and M36x2 thread handle substantial loads, ensure your external guiding mechanism is robust enough to absorb side loads, particularly since this actuator lacks a magnet for position sensing.

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 SAIJ160X125-100 FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster screw lets you trim the effective stroke within a 25-125mm travel window. It acts as a mechanical stop to set the end position and relies on the air cushion for deceleration, but it does not lock the load without continuous air pressure.
