About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX90-75S
The AirTAC SAIJ200X90-75-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. Featuring a robust 200mm bore, it delivers a substantial push force of 15708N at 0.5MPa. The integrated rear adjuster allows you to trim the 90mm nominal stroke back by up to 75mm, providing a highly versatile 15-90mm usable travel window without needing external stops.
This configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and a built-in magnet (-S) for position sensing. It operates at 30-500mm/s and uses PT tapered ports sized G3/4. The extruded aluminum barrel features sensor grooves on both sides, fully compatible with AirTAC CMSE reed and DMSE electronic switches for reliable feedback in demanding setups.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX90-75S Is Used
Heavy Press Tuning
Dial in the exact 15-90mm travel window during heavy press commissioning to accommodate varying material thicknesses without mechanical rebuilds.
Product Changeover Stops
Adjust the rear stopper on the fly during production line changeovers to instantly set new end positions for different product sizes.
High-Force Positioning
Leverage the 15708N push force to move heavy pallets or molds, fine-tuning the final resting position to within a precise millimeter range.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX90-75S the Right Cylinder?
Select this 200mm bore cylinder when an application demands extreme force, as stepping down to a 160mm bore reduces the 0.5MPa push force to 10053N. The adjustable stroke is invaluable for product changeovers, allowing operators to dial in the exact 15-90mm travel at commissioning rather than swapping cylinders. Remember that the rear screw acts purely as a travel stop; it cannot hold a load without continuous air pressure. For dead-load holding, consider an AirTAC SAIL or BSAI lock cylinder.
To replace an ISO 15552 cylinder, match the 200mm bore, 90mm stroke, 75mm adjustment range, G3/4 PT ports, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Although the stroke is under 300mm, the massive 40mm rod and M36x2 thread handle high side loads, though external guides remain essential for optimal longevity.
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 SAIJ200BX90-75S FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides a push force of 15708N and a pull force of 15080N. At the maximum 1.0MPa pressure, it achieves a push force of 3204kgf.
The rear adjuster screw allows you to shorten the 90mm nominal stroke by up to 75mm, creating a usable travel window of 15-90mm. This stopper fine-tunes the retract end position but does not lock the load without live air pressure.
