About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX150-75
The AirTAC SAIJ200X150-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning. It provides a usable travel window of 75-150 mm, allowing you to dial back the nominal 150 mm stroke by up to 75 mm during commissioning without adding external stops. Built with a SUS304 stainless steel rod and PT tapered ports, it delivers massive thrust up to 21991 N at 0.7 MPa.
This 200 mm bore unit relies on a 40 mm rod and M36x2 thread to manage substantial side loads, though long unsupported strokes still require an external guide. It uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The extruded aluminum barrel includes sensor grooves on both sides, compatible with CMSE reed and DMSE electronic switches if a magnet is added later.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX150-75 Is Used
Heavy Press Tuning
Dial in the exact 75-150 mm travel window needed for heavy-duty pressing operations, ensuring precise end-position control during machine setup.
Product Changeover
Quickly adjust the rear stopper to accommodate varying product sizes on a high-force assembly line without swapping out the entire cylinder.
Large Tooling Positioning
Fine-tune the retraction point of massive 200 mm bore tooling, leveraging the 40 mm SUS304 rod to withstand industrial stresses.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX150-75 the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires extreme push force, such as 21991 N at 0.7 MPa, exceeding the 14074 N provided by the smaller 160 mm bore. The adjustable stroke is ideal for product changeover or variable end-stop requirements, offering on-the-fly repositioning that a fixed SAI cylinder cannot match. For any stroke of 300 mm or more, you must use an external guide to prevent excessive side-loading on the rod.
Remember that the rear adjuster acts only as a mechanical stop to set deceleration and travel limits; it does not hold the load without live air pressure. If your setup requires true load-holding safety in the event of pressure loss, consider the SAIL pneumatic lock, the BSAI clamp-lock, or an external rod lock. This model is dimensionally interchangeable per ISO 15552, configured with a 150 mm stroke, 75 mm adjustment, PT ports, and no magnet.
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 SAIJ200BX150-75 FAQ
At 0.7 MPa operating pressure, this 200 mm bore cylinder generates a push force of 21991 N and a pull force of 15080 N. It can deliver a maximum push force of 28274 N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stop that shortens the effective travel. For this model, it creates a usable stroke window of 75 to 150 mm, allowing you to trim the nominal 150 mm stroke by up to 75 mm during commissioning.
