About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-10S
The AirTAC SAIJ100X30-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 5497N of push force at 0.7 MPa. It features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. The integrated rear stopper allows you to fine-tune the end position at commissioning without adding external stops.
With a 30 mm nominal stroke and a 10 mm adjustment range, this SKU provides a usable travel window of 20 to 30 mm. It uses PT tapered ports and supports adjustable air cushions at both ends. The extruded aluminum barrel includes sensor grooves on both sides, directly compatible with AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-10S Is Used
Product Changeovers
Dial in the exact end-stop from 20 to 30 mm during format changes on a packaging line, eliminating the need to physically swap cylinders for different package sizes.
Machine Setup Tuning
Fine-tune the clamping end-position at commissioning to prevent over-travel, using the rear screw to perfectly set the stroke without external mechanical stops.
High-Force Positioning
Leverage the 100 mm bore's 5497N output at 0.7 MPa to securely shift heavy actuators or gates across a short 20-30 mm travel window.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX30-10S the Right Cylinder?
Choose this 100 mm bore cylinder when an application demands high thrust (5497N at 0.7 MPa) but only short, finely tuned travel. If your force requirements are lower, stepping down to an 80 mm bore yields 3518N at 0.7 MPa, whereas moving up to 125 mm provides 8590N. The adjustable stroke is ideal for machine setups requiring a variable end-stop during product changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot match.
For load-holding applications, remember that the rear adjuster functions strictly as a travel stop, not a lock; this SAIJ cylinder will not hold its load without live air pressure. For dead-end holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. The mounting interface uses the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100BX30-10S FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 10 mm. For this 30 mm stroke model, it provides a usable travel window of 20 to 30 mm, which is set during commissioning without swapping the cylinder.
At 0.7 MPa operating pressure, the SAIJ100X30-10-S generates 5497N of push force and 3681N of pull force. It can deliver up to 7068N push force at 0.9 MPa.
