About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX195-20
The AirTAC SAIJ200X195-20 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that allows you to fine-tune the effective stroke within a 175 to 195 mm travel window. This 200 mm bore size delivers substantial thrust, providing 21991N of push force at 0.7 MPa and a maximum of 3204 kgf at 1.0 MPa. It uses a robust 40 mm SUS304 stainless steel rod and PT tapered G3/4 ports.
The rear adjustment screw acts purely as a travel stop to dial in the end position during commissioning without adding external stops; it does not lock or hold the load without continuous live air pressure. For load-holding requirements without air, an external rod lock or related types like the SAIL or BSAI are required. This profile cylinder includes sensor grooves on both sides for CMSE reed or DMSE electronic switches, though this specific SKU omits the internal magnet.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX195-20 Is Used
Heavy Press Tuning
Dial in the exact 175 to 195 mm end-stop during heavy press commissioning to compensate for mechanical deflection without swapping out the entire cylinder.
Product Changeover
Quickly adjust the retract end-position by up to 20 mm on a packaging line when switching to a different product size, saving setup time.
Massive Force Positioning
Move heavy industrial loads with up to 28274N of push force at 0.9 MPa while retaining the ability to fine-tune the travel distance on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX195-20 the Right Cylinder?
Choose this 200 mm bore adjustable cylinder when your application demands massive thrust within a 175-195 mm travel window and requires in-situ end-position tuning during machine setup or product changeover. If you need less force, stepping down to a 160 mm bore yields 14074N of push at 0.7 MPa, while sticking with the 200 mm bore provides a maximum of 3204 kgf at 1.0 MPa. Because the 195 mm stroke is substantial, the 40 mm SUS304 rod handles high side loads, but an external guide is still recommended for heavy unsupported loads.
This SAIJ configuration is dimensionally interchangeable per ISO 15552 standards. To match this exact replacement, specify a 200 mm bore, 195 mm stroke, 20 mm adjustment range, PT G3/4 port thread, SUS304 (B) rod material, no magnet, and a mounting set limited to Basic, FA, LB, TC, FTC, TCM1, or TCM2. It operates at 30-500 mm/s and utilizes 50 mm air cushions at both ends for deceleration.

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 SAIJ200BX195-20 FAQ
The rear adjuster screw lets you shorten the nominal 195 mm stroke by up to 20 mm, creating a usable travel window of 175 to 195 mm. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
At a 0.7 MPa operating pressure, it provides 21991N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 3204 kgf.
