About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X150-100S
The AirTAC SAIJ80X150-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 150 mm travel back by up to 100 mm, creating a highly flexible 50-150 mm usable window. It delivers a robust 2513 N push force at 0.5 MPa, making it well-suited for medium-to-heavy actuation tasks. The extruded aluminum barrel incorporates sensor grooves on both sides, and this -S variant includes a magnet for direct compatibility with AirTAC CMSE reed and DMSE electronic solid-state switches.
This model uses a 25 mm carbon steel piston rod with an M20x1.5 thread, providing excellent rigidity against side loads. The rear adjuster functions strictly as a mechanical stop to fine-tune the end position during commissioning or product changeovers without adding external stops. Remember that the adjuster and the variable air cushions at both ends do not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series instead. The mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X150-100S Is Used
Product Changeover
Dial the stroke back from 150 mm to 50 mm instantly on the production line when switching to a smaller product format, eliminating the need to physically swap cylinders.
End-Stop Calibration
Fine-tune the exact retracted position during machine commissioning using the rear screw, ensuring perfect alignment without adding external mechanical stops.
Variable Positioning
Actuate multiple processes with different travel requirements in a single station by adjusting the 80 mm bore's effective stroke window to match the specific task.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X150-100S the Right Cylinder?
Choose this 80 mm bore cylinder when your application requires a substantial 2513 N thrust at 0.5 MPa (or 4523 N at 0.9 MPa) alongside a widely variable end-position. The 100 mm adjustment range is particularly valuable for machines processing different product sizes, allowing operators to dial in the stroke precisely without swapping the cylinder. If your force requirements are lower, stepping down to a 63 mm bore provides 1559 N at 0.5 MPa, while moving up to a 100 mm bore yields 3927 N.
Because this is an adjustable-stroke model rather than a fixed-stroke SAI, it simplifies mechanical setup during changeovers. The cylinder operates at speeds of 30-800 mm/s and uses a PT tapered G3/8 port. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. For any application exceeding 300 mm of stroke, an external guide is recommended to prevent rod side-loading, though this 150 mm stroke is well within standard limits.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80X150-100S FAQ
This 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.9 MPa, the push force increases to 4523 N. The operational speed range is 30-800 mm/s.
The rear adjuster acts as a mechanical stop that allows you to shorten the nominal 150 mm stroke by up to 100 mm, providing a usable travel window of 50-150 mm. It sets the end position but does not lock or hold the load without continuous air pressure.
