About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX95-30S
The AirTAC SAIJ200X95-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers robust thrust, generating 15708N of push force and 15080N of pull force at 0.5 MPa. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic solid-state switches fitted into the dual-side sensor grooves.
This specific SKU features a 95 mm nominal stroke paired with a 30 mm adjustment range, yielding a usable travel window of 65 to 95 mm. The rod is constructed from SUS304 stainless steel (code B), and the pneumatic supply connects via a PT G3/4 tapered port. The extruded aluminum barrel design incorporates adjustable air cushions at both ends, each providing 50 mm of deceleration travel to manage heavy kinetic energy.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX95-30S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 65-95 mm window during machine commissioning to accommodate varying product lengths without hardware changes.
Changeover Optimization
Quickly reset the stroke end-point on packaging lines handling different package sizes, using the rear stopper instead of physically replacing the cylinder.
Heavy-Duty Forming
Leverage the 15708N push force at 0.5 MPa for high-thrust pressing and clamping operations, utilizing the 50 mm air cushions to absorb impact.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX95-30S the Right Cylinder?
Choose this 200 mm bore when your application requires maximum output force, stepping up from the 160 mm bore that provides 10053N push force at 0.5 MPa. The 30 mm rear adjuster screw acts as a travel stopper to fine-tune the retract end position during commissioning or product changeover without adding external stops or swapping a fixed-stroke SAI cylinder. The SAIJ mounting interface is dimensionally interchangeable per ISO 15552 and supports a reduced set of attachments: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
Because the 95 mm stroke exceeds 300 mm? No, but for any long travel exceeding 300 mm, an external guide is recommended to manage side loads. Note that the rear adjuster and air cushions only set the travel end and decelerate the load; they do not function as a lock. For load-holding without live air pressure, select an AirTAC SAIL pneumatic lock, BSAI clamp-lock cylinder, or an external pilot-operated check valve. The 200 mm bore operates at speeds of 30-500 mm/s.

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 SAIJ200BX95-30S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708N of push force and 15080N of pull force. It can achieve a maximum thrust of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stopper that allows you to trim the effective stroke back by up to 30 mm. This creates a usable travel window between 65 mm and 95 mm, enabling fine-tuning of the end position without replacing the cylinder.
