About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX135-75S
The AirTAC SAIJ200X135-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers exceptional power, providing 21991N of push force at 0.7 MPa. The external stopper lets you dial back the nominal 135 mm travel by up to 75 mm, creating a precise 60-135 mm usable window for product changeovers without swapping hardware.
This configuration includes a SUS304 stainless steel rod for corrosion resistance and a magnetic piston for position sensing. It supports AirTAC CMSE reed and DMSE solid-state switches in the dual-side sensor grooves. The rear adjuster acts purely as a travel stop to set end positions; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX135-75S Is Used
Variable End-Stop Tuning
Dial in the exact 60-135 mm retract position during machine setup to accommodate different material thicknesses without changing cylinders.
Product Size Changeover
Rapidly adjust the stroke window on packaging lines handling varied container sizes, leveraging the 21991N force to move heavy loads.
Heavy Assembly Pressing
Apply precise clamping or pressing force at a specific travel endpoint, using the SUS304 rod in environments requiring high corrosion resistance.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX135-75S the Right Cylinder?
Choose this 200 mm bore when you need maximum thrust in a compact footprint, stepping up from a 160 mm bore that yields 14074N push at 0.5 MPa. The adjustable 75 mm window is ideal for lines running mixed product sizes, removing the need to physically swap cylinders or bolt on external stops during commissioning.
For load-holding without continuous air pressure, select a SAIL or BSAI variant, as the SAIJ adjuster is not a lock. This unit uses a PT tapered port and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR. Although the stroke is 135 mm, the heavy 40 mm rod and M36x2 thread handle high stresses, yet any long unsupported overhang still requires an external guide.
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 SAIJ200BX135-75S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 135 mm nominal stroke by up to 75 mm. This creates a usable 60-135 mm window, but it only sets the end position; it does not lock or hold the load without live air pressure.
At 0.7 MPa, the SAIJ200X135-75-S generates 21991N of push force and 15080N of pull force. It can achieve up to 15708N push at 0.5 MPa, with a maximum operating pressure of 1.0 MPa.
