About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX260-40
The AirTAC SAIJ200X260-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 220-260 mm window. Equipped with a SUS304 stainless steel rod and PT tapered ports, it delivers massive thrust up to 28274N at 0.9 MPa, making it ideal for heavy-duty pressing. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE electronic switches.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during machine commissioning. The rear adjuster acts purely as a mechanical travel stop to set the retract end-position, working alongside the built-in 50 mm air cushions to decelerate the load. It is not a locking device; for load-holding without live air pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX260-40 Is Used
Heavy Pressing Operations
Dial in the exact 220-260 mm end-stop for heavy pressing tasks, ensuring perfect material deformation without over-traveling the 200 mm bore.
Product Size Changeovers
Quickly adjust the retract end-position by up to 40 mm during product size transitions on the line, avoiding the need to physically swap out the entire cylinder.
Automated Machine Setup
Use the rear mechanical stopper to fine-tune the end position during initial machine commissioning, compensating for mechanical tolerances on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX260-40 the Right Cylinder?
Choose this 200 mm bore when your application requires the highest force output, pushing 28274N at 0.9 MPa. If you need slightly less force, stepping down to a 160 mm bore yields 18095N of push at 0.9 MPa. The 40 mm adjustment range is perfect for variable end stops and product-size changeovers on a line, whereas a fixed SAI cylinder is better for rigid, repeatable end positions. To replace this cylinder on an ISO 15552 footprint, match the 200 mm bore, 260 mm stroke, 40 mm adjustment, PT port thread, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set.
With a 260 mm stroke, the 40 mm diameter rod and M36x2 thread provide excellent rigidity, but long unsupported strokes still require an external guide to prevent side-loading damage. The standard speed range for this large bore is 30-500 mm/s.
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 SAIJ200BX260-40 FAQ
At 0.9 MPa operating pressure, this 200 mm bore cylinder generates a push force of 28274N and a pull force of 15080N. It can achieve a maximum push force of 15708 kgf at 1.0 MPa.
The rear adjuster screw allows you to mechanically shorten the nominal 260 mm stroke by up to 40 mm, providing a usable travel window of 220 to 260 mm. The adjuster acts as a travel stop to set the end position and does not lock or hold the load without continuous air pressure.
