About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-20S
The AirTAC SAIJ100X230-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. It provides a usable travel window of 210 to 230 mm, letting you dial back the nominal 230 mm stroke by up to 20 mm during commissioning. Built with a SUS304 stainless steel rod, it delivers a robust 3927 N push force at 0.5 MPa and uses G1/2 ports.
This model includes a magnet for position sensing with CMSE reed and DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting. It supports a standard mounting subset including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR configurations.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-20S Is Used
Product Changeover
Quickly adjust the end-of-stroke position by up to 20 mm to accommodate different product sizes on the same production line without changing cylinders.
Machine Setup
Fine-tune the final retracted position during commissioning to achieve precise mechanical alignment without adding external stopper blocks.
Heavy Forming
Leverage the 3927 N push force at 0.5 MPa for pressing or forming tasks where the exact travel distance needs minor on-site calibration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-20S the Right Cylinder?
Choose this 100 mm bore when you need higher thrust than a neighboring 80 mm cylinder, which provides 2513 N of push force at 0.5 MPa. The adjustable stroke is ideal for applications requiring variable end stops or product changeovers without swapping the cylinder. The rear screw acts purely as a travel stop and does not hold the load without live air; for load-holding without pneumatic pressure, consider an external rod lock or the SAIL series.
For a direct ISO 15552 replacement match, verify a 100 mm bore, 230 mm stroke, 20 mm adjustment, PT tapered port threads, and the -S magnet option. Because the 230 mm stroke is relatively long, ensure external guides are used to support the load and prevent excessive side loading on the 25 mm rod.
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 SAIJ100BX230-20S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the effective stroke from its nominal 230 mm down to 210 mm. This creates a 210-230 mm adjustable travel window for fine-tuning the end position without altering the cylinder mounting.
