About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-10S
The AirTAC SAIJ100X75-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to fine-tune the travel window from 65 to 75 mm during commissioning. Delivering 3927 N of push force at 0.5 MPa, it handles substantial workloads while allowing precise end-position calibration without external stops.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for position detection using CMSE reed or DMSE electronic sensors. It uses a PT tapered G1/2 port and variable air cushions at both ends, while the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-10S Is Used
Machine Setup Calibration
Dial in the exact 65-75 mm end-position during initial commissioning to perfect part seating without machining custom spacers.
Product Changeover
Quickly trim the stroke by up to 10 mm on the rear stopper when switching the production line to a slightly shorter workpiece.
Assembly Pressing
Leverage the 3927 N push force at 0.5 MPa to seat heavy components, using the fine adjustment to prevent over-travel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX75-10S the Right Cylinder?
Choose this 100 mm bore when 982 N from a 50 mm bore is insufficient, but you want to avoid the heavier 125 mm class. The 10 mm adjustment range is ideal for dialing in exact end-stops during machine setup or product changeover, replacing the need to swap a fixed-stroke SAI cylinder.
For strokes of 75 mm, side-load risks are minimal, but always guide the load. Remember that the rear adjuster is a travel stop, not a lock; this SAIJ cylinder cannot hold a load without live air. For fail-safe holding, select a SAIL or BSAI cylinder. This unit is dimensionally interchangeable per ISO 15552.
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 SAIJ100BX75-10S FAQ
The rear adjuster acts as a mechanical stop that shortens the effective stroke by up to 10 mm. This gives the 75 mm stroke a usable travel window of 65 to 75 mm, which can be fine-tuned during commissioning without swapping the cylinder.
At a 0.5 MPa operating pressure, it provides 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N of push force at 0.9 MPa.
