About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-20S
The AirTAC SAIJ200X1000-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. With a nominal 1000 mm stroke and a 20 mm adjustment screw, it provides a usable travel window of 980-1000 mm for exact commissioning without external stops. This massive 200 mm bore delivers up to 28274 N of push force at 0.9 MPa, making it ideal for heavy-duty pressing and lifting.
Equipped with a SUS304 stainless steel rod (code B) and a PT tapered port, this made-to-order unit handles long-stroke demands while retaining the standard ISO 15552 mounting interface. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors for precise position feedback.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-20S Is Used
Heavy Press Fine-Tuning
Dial in the exact 980-1000 mm travel during heavy press commissioning to accommodate different material thicknesses without changing the cylinder.
Large Assembly Changeover
Adjust the retract end position rapidly during product size changeovers on large-scale assembly lines, saving setup time and tooling costs.
Variable End-Stop Positioning
Use the 20 mm rear adjustment screw to set precise end-stops for oversized component handling, avoiding the need to install external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX1000-20S the Right Cylinder?
Choose this 200 mm bore when your application requires extreme thrust that smaller bores cannot provide, such as heavy mold handling or large press operations. If the full 28274 N push force at 0.9 MPa is excessive, stepping down to a 160 mm bore yields 18095 N, offering a lighter, more compact footprint while retaining the same ISO 15552 interchangeability.
The adjustable stroke is perfect for variable end-stop requirements or product changeovers, eliminating the need to swap cylinders or bolt on external stop blocks. Because this is a 1000 mm stroke, the 40 mm rod and M36x2 thread provide robust support, but an external guide is strongly recommended to manage side loads and prevent rod deflection over the long unsupported travel. Remember that the rear adjuster is a travel stop, not a lock; for fail-safe load holding without live air pressure, select a SAIL or BSAI cylinder. This SAIJ configuration uses the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ200BX1000-20S FAQ
At 200 mm bore, it delivers a push force of 21991 N at 0.7 MPa and 28274 N at 0.9 MPa, with a maximum push force of 3204 kgf at 1.0 MPa. The pull force at 0.5 MPa is 15080 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm. For this 1000 mm stroke model, it creates an adjustable travel window of 980-1000 mm, letting you fine-tune the end position at commissioning. The adjuster acts as a stop and does not lock the load without live air pressure.
