About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX750-75S
The AirTAC SAIJ200X750-75-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 21991N push force at 0.7 MPa. It features a rear-mounted stroke adjuster that allows you to fine-tune the end-of-travel position, creating a usable window of 675 to 750 mm without adding external stops. The 750 mm stroke falls within the standard limit for this bore, while the -S magnet enables precise position tracking via CMSE reed and DMSE electronic sensors.
This variant utilizes a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered port threads. Unlike fixed-stroke SAI units, the external rear stopper lets you dial in the exact retract distance during commissioning or product changeovers. Remember that the adjuster functions purely as a travel stop to set deceleration endpoints; it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX750-75S Is Used
Heavy Machinery Changeover
Adjust the 75 mm travel window during production line changeovers to accommodate different large-scale product dimensions without replacing the cylinder.
Large Assembly Pressing
Delivers up to 21991N of push force at 0.7 MPa for securely seating heavy components, with fine-tuning available at the rear stopper for precise end-positioning.
Bulk Material Diverter
Handles heavy diverter arms on bulk conveyor systems, using the SUS304 rod for environmental resilience and the adjustable end-stop to set exact gating distances.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX750-75S the Right Cylinder?
Select this 200 mm bore cylinder when your machinery requires maximum thrust, as stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053N. The adjustable stroke is ideal for production lines handling varying product sizes, allowing operators to reposition the end stop by up to 75 mm rather than swapping the entire actuator. For load-holding requirements without continuous air pressure, this cylinder is insufficient; you should instead consider an SAIL air-released lock or BSAI clamp-lock unit.
When replacing an actuator, match the 200 mm bore, 750 mm nominal stroke, 75 mm adjustment range, PT G3/4 port, and the -S magnet requirement. Because the 750 mm stroke creates a long unsupported rod, you must use an external guide to prevent excessive side-load wear. This SAIJ model uses the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ200BX750-75S FAQ
At a 0.7 MPa operating pressure, this 200 mm bore cylinder provides 21991N of push force and 19194N of pull force. At the maximum 1.0 MPa pressure, it achieves a push force of 31416N.
The rear adjuster screw acts as an external stopper, allowing you to shorten the effective travel from the 750 mm nominal stroke down to 675 mm. This creates a 675-750 mm adjustable window for fine-tuning the retract position at commissioning without swapping the cylinder.
