About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-50
The AirTAC SAIJ100X95-50 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 3927N of push force at 0.5MPa and provides a usable travel window of 45-95mm, letting you dial in the exact end position without swapping hardware. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This unit is configured with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered ports. The rear stopper acts solely as a travel limit and relies on live air to maintain position; it does not function as a lock. For load-holding without air pressure, consider an external rod lock or the AirTAC SAIL series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-50 Is Used
Product Size Changeovers
Quickly adapt end-stops on packaging lines processing different carton lengths without changing the cylinder.
Commissioning Calibration
Fine-tune the 45-95mm travel window during machine setup to achieve perfect seating force against varying workpieces.
Heavy Forming Stops
Leverage the 3927N push force at 0.5MPa for pressing applications while using the adjuster to prevent over-travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-50 the Right Cylinder?
Choose this 100mm bore when you need heavy thrust beyond the 50mm bore's 982N push at 0.5MPa, but want to avoid the larger 125mm footprint. The 50mm adjustment range is ideal for prototyping or production lines handling varying product sizes, allowing rapid changeovers. Unlike a fixed-stroke SAI cylinder, this adjustable model fine-tunes the retract end-stop at commissioning without adding external stops.
When replacing an ISO 15552 cylinder, match the 100mm bore, 95mm nominal stroke, 50mm adjustment, PT port thread, and your required mounting style. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is under 300mm, side-load stress is minimal, but always guide the load for optimal bearing life.
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 SAIJ100BX95-50 FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw lets you mechanically shorten the 95mm nominal stroke by up to 50mm, providing an effective travel range of 45-95mm. This stopper only limits travel and requires live air to hold the load.
