About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX195-75S
The AirTAC SAIJ200X195-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 195 mm travel by up to 75 mm. This yields a precise usable travel window of 120-195 mm, ideal for setting exact retract end-positions during machine commissioning without swapping out the hardware. As the largest bore in the series, it delivers immense thrust, generating 15708 N of push force and 15080 N of pull force at a 0.5 MPa operating pressure.
This specific SKU ships with a SUS304 stainless steel rod (material code B) for superior corrosion resistance and features PT tapered port threads. It includes a magnet (-S) for position sensing, working seamlessly with AirTAC CMSE reed switches and DMSE solid-state electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the unit relies on a robust 40 mm variable air cushion at both ends to decelerate heavy loads across its 30-500 mm/s speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX195-75S Is Used
Heavy Press Tonnage Tuning
Dial in the exact 120-195 mm retract distance on a heavy stamping press to accommodate varying material thicknesses without recalculating fixed stop lengths.
Large Assembly Line Changeover
Rapidly redefine the end-stop position during automated product changeovers, using the 75 mm adjustment window to handle different large-component dimensions.
High-Force Positioning
Leverage the 15708 N push force at 0.5 MPa to shift heavy pallets or industrial molds into precise final positions before a secondary locking mechanism engages.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX195-75S the Right Cylinder?
Selecting this 200 mm bore makes sense when your application requires moving substantial masses, as it outputs up to 21991 N of push force at 0.7 MPa; if you can lighten the payload, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa. The 75 mm rear adjustment screw is highly valuable for product changeovers, letting operators redefine the retract end-stop on the fly. Remember that this rear adjuster functions strictly as a travel stop and cushioning regulator—it does not lock the load. If the machine loses air pressure, the cylinder will drift; for true fail-safe load holding without live air, you must integrate an external rod lock or specify a SAIL or BSAI series cylinder.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 200 mm bore, 195 mm stroke, 75 mm adjustment range, PT G3/4 port, and the -S magnet requirement. Because the stroke is 195 mm, you avoid the external guide complications of longer strokes, though the massive 40 mm rod and M36x2 thread naturally handle high bending stresses. Mounting is limited to the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on fixed-stroke variants.

- ✓ 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 SAIJ200BX195-75S FAQ
The rear adjuster screw acts as an external stopper that shortens the effective stroke. For this model, you can trim the nominal 195 mm stroke back by up to 75 mm, creating a usable travel window of 120-195 mm to fine-tune the retract end-position at commissioning.
At 0.5 MPa, it provides 15708 N of push force and 15080 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 21991 N, making it suitable for heavy-duty pressing and moving tasks.
