About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-75
The AirTAC SAIJ100X175-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that creates a 100-175 mm usable travel window from its 175 mm nominal stroke. Delivering 7068N of push force at 0.9 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This adjustable model lets you fine-tune the retract end position during commissioning or product changeovers without swapping the cylinder or adding external stops. It supports a standard operating speed of 30-800 mm/s and features adjustable air cushions at both ends to manage kinetic energy, though the rear adjuster functions strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-75 Is Used
Variable End Stops
Dial in the retract distance by up to 75 mm to accommodate different material thicknesses or tooling offsets without replacing the actuator.
Machine Setup Changeover
Quickly fine-tune the 100-175 mm travel window during line changeovers to minimize downtime and avoid adding external mechanical stops.
Heavy-Duty Positioning
Leverage the 7068N push force and SUS304 rod for robust, corrosion-resistant positioning in demanding industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX175-75 the Right Cylinder?
Select this 100 mm bore when your application requires heavy thrust—up to 7068N push at 0.9 MPa—and a highly flexible end-position window. If you need less force, stepping down to an 80 mm bore yields 4523N push, whereas a 125 mm bore provides 11045N for heavier loads. The generous 75 mm adjustment range is ideal for machinery that handles varying product sizes, allowing operators to dial in the exact stroke without mechanical modifications.
Because this is a double-acting cylinder, the rear adjuster and air cushions only decelerate the travel end; they do not function as a lock. For load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder, or use an external pilot-operated check valve. This SAIJ configuration uses a PT port, omits the -S magnet, and supports the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) without FB, CA, CB, or CR options. As a profile cylinder, it is dimensionally interchangeable per ISO 15552.

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 SAIJ100 Adjustable Cylinder SAIJ100BX175-75 FAQ
At an operating pressure of 0.9 MPa, this 100 mm bore cylinder provides a push force of 7068N and a pull force of 3681N. The maximum thrust at 1.0 MPa is 801 kgf.
The rear adjusting screw acts as a mechanical stop that lets you trim the effective travel back by up to 75 mm from the 175 mm nominal stroke, creating a 100-175 mm usable window. It sets the end position but does not lock or hold the load without continuous air pressure.
