About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX850-100S
The AirTAC SAIJ200X850-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers immense thrust, generating 15708N of push force and 15080N of pull force at 0.5 MPa. The integrated -S magnet enables position sensing across both sensor grooves using AirTAC CMSE reed and DMSE electronic solid-state switches. This heavy-duty unit features a SUS420J2 stainless steel rod and PT tapered port threads.
With a nominal 850 mm stroke and a 100 mm adjustment range, this model provides a usable travel window of 750-850 mm. You can fine-tune the retract end-position at commissioning or during product changeovers without swapping the cylinder or adding external stops. The rear adjuster screw acts purely as a travel stop to set deceleration; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX850-100S Is Used
Heavy Press Tuning
Dial in the exact 750-850 mm end-stop for large metal forming or heavy press operations without changing the cylinder.
Product Size Changeover
Quickly adapt long-stroke material handling lines to different pallet or product lengths by adjusting the travel limit up to 100 mm.
Large Assembly Setup
Fine-tune the retract position during the commissioning of large-scale automated assembly machinery to ensure perfect alignment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX850-100S the Right Cylinder?
Choose this 200 mm bore when your application requires maximum force (up to 3204 kgf at 1.0 MPa) over a long 750-850 mm travel window. If your setup needs less force, stepping down to a 160 mm bore yields 10053N push force at 0.5 MPa, which might better suit medium-duty tasks. Because the 850 mm stroke is substantial and the 40 mm rod is heavy, an external guide is strongly recommended to prevent excessive side-loading and rod deflection.
Select the adjustable SAIJ over a fixed-stroke SAI when you need variable end-stops for machine setup or accommodating varying product sizes. Remember that the rear adjuster is a stop, not a lock; for load-holding without live air pressure, use an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder. For a direct ISO 15552 replacement, match the 200 mm bore, 850 mm stroke, 100 mm adjustment, PT G3/4 ports, SUS420J2 rod, and -S magnet, utilizing the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set.

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 SAIJ200AX850-100S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 850 mm stroke by up to 100 mm, creating a 750-850 mm usable window. The adjuster acts only as a mechanical stop to set the end position and does not lock or hold the load without continuous air pressure.
