About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-75
The AirTAC SAIJ200X170-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 75 mm of travel reduction. This creates a usable 95-170 mm stroke window, enabling precise end-position tuning at commissioning without swapping the barrel or adding external stops. Built with a SUS420J2 stainless steel rod, it delivers 15708 N of push force at 0.5 MPa.
The rear screw acts purely as a mechanical travel stop to set the retract position; it does not lock or hold the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, and fluid supply connects via PT G3/4 tapered ports. It supports speeds of 30-500 mm/s and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-75 Is Used
Heavy Press Tuning
Dial in the exact 95-170 mm retract distance during machine setup to accommodate varying material thicknesses in high-force pressing operations.
Product Changeover
Adjust the end-stop on the fly during production line changeovers without removing the cylinder or bolting on new external stopper blocks.
Variable End Stops
Set precise retract positions for heavy-duty forming or bending jigs where the final stroke length must be tweaked per workpiece.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-75 the Right Cylinder?
Select this 200 mm bore cylinder when an application requires heavy thrust up to 15708 N at 0.5 MPa combined with variable end-stop positioning. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N of push force. The 75 mm adjustment range is ideal for product changeovers on a line, allowing operators to dial in the exact 95-170 mm travel window on the fly rather than maintaining an inventory of fixed-stroke SAI cylinders.
Because the 170 mm stroke is below the 300 mm side-load threshold, standard mounting is sufficient, though long unsupported loads should still use an external guide. Remember that the rear adjuster and air cushions only decelerate the travel end; for true load-holding without live pressure, specify an external rod lock or choose the SAIL or BSAI series. This SKU is dimensionally interchangeable per ISO 15552 using a 200 mm bore, 170 mm stroke, 75 mm adjustment, PT G3/4 ports, and no magnet.

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 SAIJ200 Adjustable Cylinder SAIJ200AX170-75 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw allows you to shorten the nominal 170 mm stroke by up to 75 mm, creating a usable travel window of 95 to 170 mm. This stopper only sets the end position and does not hold the load without live air.
