About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-100S
The AirTAC SAIJ100X110-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3927N of push force at 0.5 MPa and features a PT tapered port thread alongside a SUS420J2 stainless steel rod. Because this specific SKU carries a 100mm adjustment code on a 110mm nominal stroke, you gain an exceptionally wide usable travel window from 10mm up to 110mm without changing the physical cylinder.
This built-in adjustability allows you to dial in the exact retract end-position during commissioning or product changeovers, eliminating the need to bolt on external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position detection. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-100S Is Used
Variable End-Stop Positioning
Ideal for assembly stations requiring different retract distances, allowing operators to trim the stroke from 110mm down to 10mm on the fly for varying component heights.
Machine Changeover
Speeds up product line changeovers by using the rear adjuster to set new end positions instantly, avoiding the downtime of physically swapping cylinders or adding spacer blocks.
Precision Clamping Setup
Provides fine-tuning of the clamping reach during initial machine commissioning, ensuring the 3927N thrust is applied at the exact required position without mechanical rework.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-100S the Right Cylinder?
Choose this 100mm bore when an 80mm bore (delivering 2513N push at 0.5 MPa) is insufficient for your workpiece, or step down if you do not need the 3927N thrust this model provides. An adjustable stroke is selected over a fixed SAI cylinder when a machine handles multiple product sizes and requires rapid end-stop tuning without hardware swaps. For load-holding without continuous air pressure, this cylinder is insufficient; you must integrate an external rod lock, a pilot-operated check valve, or switch to the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder, specify the 100mm bore, 110mm stroke, 100mm adjustment, PT port, SUS420J2 rod, and the -S magnet.
Because the nominal stroke is 110mm, the 25mm rod handles side loads well, but you should still verify that the piston rod is not subjected to excessive lateral forces. Mounting options for the SAIJ series include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

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 SAIJ100AX110-100S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 100mm. This gives the 110mm nominal stroke a usable travel window of 10mm to 110mm, which can be fine-tuned during operation without swapping the cylinder.
At an operating pressure of 0.5 MPa, the SAIJ100X110-100-S provides a push force of 3927N and a pull force of 3681N. At 0.9 MPa, the push force increases to 7068N.
