Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-50S
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 150mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-50S
The AirTAC SAIJ100X150-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 100 to 150 mm. Built with a SUS420J2 stainless steel rod and a PT tapered port, it delivers a robust 3927 N push force at 0.5 MPa. The integrated -S magnet enables precise position detection using AirTAC CMSE reed or DMSE solid-state sensors seated in the dual-sided extruded aluminum barrel grooves.
Unlike a fixed-stroke SAI cylinder, this model allows you to dial back the nominal 150 mm stroke by up to 50 mm at the retract end. This built-in mechanical stopper lets you fine-tune end positions during commissioning or product changeovers without adding external stops. The rear adjuster and air cushions only decelerate the travel end, so a separate SAIL or BSAI locking cylinder is required to hold loads without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-50S Is Used
Product Size Changeovers
Dial in the 100 to 150 mm travel window instantly on the rear stopper when line dimensions change, avoiding mechanical rebuilds.
Machine Setup Tuning
Fine-tune the retract end position during initial commissioning without swapping out the entire ISO 15552 cylinder or adding external stops.
Variable End-Stop Positioning
Use the 50 mm adjustment range to alter the final resting position of the tooling for different production batches on the same assembly line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX150-50S the Right Cylinder?
Choose this 100 mm bore when the 50 mm bore's 982 N push force at 0.5 MPa is insufficient, but you want to avoid the larger 125 mm footprint. The 50 mm adjustment range is ideal for machines processing varying product sizes, allowing rapid end-stop tuning without cylinder replacement. When matching an ISO 15552 replacement, verify the 150 mm stroke, 50 mm adjuster, PT G1/2 port, and the -S magnet requirement.
For any stroke of 300 mm or more, an external guide is recommended to prevent excessive side-loading on the rod. This SAIJ model utilizes the reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The 25 mm rod and M20x1.5 thread handle high side loads, but always support long unsupported loads externally.
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 SAIJ100AX150-50S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. The maximum push force reaches 7068 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back from the 150 mm nominal stroke down to 100 mm. It sets the end position but does not lock the load without live air pressure.
