About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX550-10S
The AirTAC SAIJ100X550-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 540-550 mm usable travel window, allowing you to dial back the 550 mm nominal stroke by up to 10 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance.
This model includes a magnet for position sensing, working seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without needing external stops, though it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX550-10S Is Used
Product Changeover
Dial in the 10 mm stroke adjustment during line changeovers to accommodate slightly different product lengths without swapping the entire cylinder assembly.
Variable End Stops
Use the rear stopper to set precise retract positions for testing fixtures, allowing fine-tuning of the 540-550 mm travel window on the fly.
Corrosive Environments
Leverage the SUS304 stainless steel rod and 3927 N thrust for heavy-duty pushing tasks in washdown or corrosive manufacturing settings.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX550-10S the Right Cylinder?
Choose this 100 mm bore cylinder when you need 3927 N of push force at 0.5 MPa (or 7068 N at 0.9 MPa) and precise end-position tuning. If your application requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. The adjustable stroke is ideal for product changeovers where a fixed SAI cylinder would require physical swapping.
Because the 550 mm stroke is relatively long, ensure an external guide supports the load to prevent excessive side-loading on the SUS304 rod. This cylinder uses a PT tapered G1/2 port and supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. For applications requiring true load-holding without live air, consider the SAIL or BSAI series instead.
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 SAIJ100BX550-10S 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 the maximum pressure of 0.9 MPa, it delivers 7068 N of push force.
The rear adjusting screw lets you shorten the effective travel by up to 10 mm, creating a 540-550 mm usable stroke window. It acts as a mechanical stop for end-position tuning and does not lock the load without continuous air pressure.
