About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-50S
The AirTAC SAIJ100X80-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, providing 3927N of push force and 3681N of pull force at 0.5 MPa. The integrated -50 adjustment code allows you to trim the nominal 80mm stroke backward, creating a highly specific 30-80mm usable travel window for exact end-position tuning.
This configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions, while the rear adjuster acts purely as a mechanical stop to set the retraction end without holding the load pneumatically.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-50S Is Used
Product Changeover Tuning
Dial in the 30-80mm travel window during format changes on a packaging line, using the rear stopper to set exact retraction depths without changing the cylinder.
High-Force End Positioning
Leverage the 3927N push force at 0.5 MPa to securely press or form components, relying on the fine adjustment screw to dial out mechanical slack during commissioning.
Sensor-Driven Clamping
Utilize the integrated magnet with DMSE electronic sensors to confirm clamp positions, while the SUS304 rod provides reliable performance in humid production environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-50S the Right Cylinder?
Choose this 100mm bore when an 80mm bore is insufficient, stepping up from the 80mm's 2513N push force to a robust 3927N at 0.5 MPa. The adjustable stroke is selected over a fixed SAI cylinder when a machine requires variable end-stops or fine-tuning during product changeovers, eliminating the need to physically swap out hardware. Because the stroke is 80mm, external side-load guides are less critical than on longer strokes, though the robust M20x1.5 rod thread handles typical loads well.
For a true ISO 15552 replacement, match the 100mm bore, 80mm nominal stroke, 50mm adjustment range, PT tapered port threads, and the -S magnet requirement. Remember that the rear adjuster only sets the travel limit; it does not lock the load. If your application requires pneumatic load-holding without live air pressure, consider the SAIL or BSAI cylinder series instead.
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 SAIJ100BX80-50S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N.
The rear adjuster screw allows you to shorten the nominal 80mm stroke by up to 50mm, creating a usable travel window of 30-80mm. The adjuster acts as a mechanical stop and does not lock the load without live air pressure.
