About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX950-75S
The AirTAC SAIJ200X950-75-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications. It features a robust 200mm bore generating 15708N of push force at 0.5MPa and a 950mm stroke. Equipped with a rear adjustment screw, this model allows you to fine-tune the effective travel down by up to 75mm, creating a precise usable stroke window between 875 and 950mm. This built-in adjustability eliminates the need to swap cylinders or bolt on external stops during machine commissioning.
Built for durability and precise feedback, this unit includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and a magnetic piston for position sensing. The sensor groove on both sides of the extruded aluminum barrel accepts AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid ports are PT tapered thread G3/4, and the unit relies on variable air cushions at both ends to decelerate the massive 3204kgf maximum load safely.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX950-75S Is Used
Heavy Press Tuning
Dial in the exact 875-950mm end-position for large metal forming or pressing tasks during machine setup without changing the actuator.
Product Size Changeover
Quickly adjust the travel stop to accommodate varying pallet or product lengths on a high-capacity conveyor line.
Assembly Line Calibration
Fine-tune the retract end-stop during commissioning of heavy automated assembly equipment to ensure perfect alignment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX950-75S the Right Cylinder?
Choose this 200mm bore when 160mm (10053N push at 0.5MPa) cannot move your load, as the step up to 200mm provides 15708N of thrust. An adjustable stroke is preferred over a fixed SAI cylinder when you need variable end-stops to accommodate product size changes on a line without physically replacing the actuator. Because the stroke is 950mm, the long unsupported travel demands an external guide to prevent side-loading damage to the rod and seals.
When matching your ISO 15552 replacement, verify the 200mm bore, 950mm stroke, 75mm adjustment range, G3/4 PT ports, and the -S magnet. Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ200BX950-75S FAQ
At 0.5MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum operating pressure of 1.0MPa, it delivers up to 3204kgf of push force.
The rear adjuster screw lets you shorten the 950mm nominal stroke by up to 75mm, giving a usable travel window of 875 to 950mm. This stopper only sets the end position and does not lock the load without live air pressure.
