About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-75S
The AirTAC SAIJ100X200-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 75 mm. This creates a highly versatile 125-200 mm usable stroke window, letting you fine-tune the retract end-position at commissioning without swapping out the unit or adding external stops. Delivering 3927 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing.
The 25 mm rod and M20x1.5 thread provide a robust interface that handles high side loads well, though any stroke near or over 300 mm still requires an external guide. Unlike fixed-stroke SAI models, this adjustable variant excels in setups requiring variable end-stops. The rear screw acts purely as a travel stop, meaning it cannot hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI locking cylinders. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-75S Is Used
Variable End-Stop Machining
Dial in the exact 125-200 mm retract distance during machine setup to accommodate different part lengths without installing external hard stops.
Product Size Changeover
Quickly adjust the stroke window up to 75 mm during production line changeovers to handle varying package or material sizes efficiently.
Corrosive Assembly Stations
Leverage the SUS304 stainless steel rod and 3927 N push force for robust, reliable actuation in washdown or corrosive manufacturing environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-75S the Right Cylinder?
Choose this 100 mm bore when your application demands substantial thrust; stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, while moving up to 125 mm provides 6136 N. The 75 mm adjustment range is ideal for machines that process varying product sizes, allowing operators to dial in the exact retract distance during changeovers rather than fabricating new hard stops.
To match this cylinder as an ISO 15552 replacement, verify the 100 mm bore, 200 mm nominal stroke, 75 mm adjustment code, PT tapered port thread, and the -S magnet. The integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors mounted in the dual-side barrel grooves. Remember that the adjuster only decelerates and sets the travel end, so an external rod lock is required if the load must be held without continuous air supply.
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 SAIJ100 Adjustable Cylinder SAIJ100BX200-75S FAQ
At 0.5 MPa, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa operating pressure, it delivers up to 801 kgf.
The rear adjuster screw lets you shorten the nominal 200 mm stroke by up to 75 mm, creating a 125-200 mm usable travel window. It functions as a mechanical stop to tune the end position and does not lock the load without live air pressure.
