About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX275-10S
The AirTAC SAIJ100X275-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 275 mm stroke that can be dialed back by up to 10 mm, creating a precise 265-275 mm usable travel window for end-position tuning. In the 100 mm bore class, it delivers 3927 N of push force and 3681 N of pull force at 0.5 MPa.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a piston magnet (-S) for solid-state DMSE electronic or CMSE reed switch integration. The extruded aluminum barrel carries sensor grooves on both sides. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX275-10S Is Used
Product Changeover Tuning
Dial in the 265-275 mm travel window during packaging line format changes to set exact end positions without machining new stopper blocks.
Commissioning End-Stop
Fine-tune the retract end position at machine startup to absorb mechanical tolerances, using the rear screw instead of adjusting fixed SAI cylinder mounts.
Long-Stroke Assembly
Drive heavy press operations with 3927 N of push force at 0.5 MPa while relying on the 10 mm adjuster to set the precise final clamping position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX275-10S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires fine end-position tuning at commissioning or during product changeover without physically swapping the cylinder or adding external stops. If you need less force, stepping down to a 63 mm bore yields 1559 N of push force at 0.5 MPa. Since the 275 mm stroke is relatively long, ensure external guidance is used to prevent side-load damage to the M20x1.5 rod thread.
To replace an ISO 15552 cylinder, match the 100 mm bore, 275 mm stroke, 10 mm adjustment, PT tapered G1/2 port, and the -S magnet requirement. Remember that the rear adjuster acts only as a travel stop and the air cushions only decelerate the load. Neither holds the load without live air pressure. For true load-holding without continuous air, use an SAIL air-released lock, a BSAI clamp-lock, or an external rod lock.
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 SAIJ100BX275-10S FAQ
At a 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 lets you shorten the effective travel from the nominal 275 mm down to 265 mm. This creates a 10 mm tuning window for precise end-position setup without replacing the cylinder.
