About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX85-75
The AirTAC SAIJ100X85-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. With an 85mm nominal stroke and a 75mm adjustment range, the usable travel window is 10-85mm. This wide trim capacity is ideal for dialing in exact end positions during machine commissioning without swapping hardware.
This model features a SUS304 stainless steel rod (code B) for superior corrosion resistance. It uses a PT tapered G1/2 port and includes variable air cushions at both ends. The rear adjuster acts as a mechanical stop to set the travel end, not a lock, so it will not hold a load without live air pressure. For position holding, consider SAIL or BSAI cylinders.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX85-75 Is Used
Product Changeover
Dial in new end positions rapidly when switching product sizes on a packaging line without changing the cylinder.
Commissioning Tuning
Fine-tune the exact 10-85mm travel window during machine setup to perfect positioning without adding external stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX85-75 the Right Cylinder?
The 75mm adjustment range on an 85mm stroke is perfect for applications needing variable end stops or frequent product-size changeovers, unlike a fixed-stroke SAI cylinder. Since the stroke is under 300mm, side-load risks are minimal, but external guides are still recommended for heavy radial loads.
When replacing an ISO 15552 cylinder, match the 100mm bore, 85mm stroke, 75mm adjustment, PT G1/2 port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting options. No magnet is specified, so CMSE or DMSE sensors cannot be used without modification.
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 SAIJ100BX85-75 FAQ
The 85mm nominal stroke can be mechanically dialed back by up to 75mm via a rear adjusting screw, providing a usable travel window of 10-85mm. The adjuster acts as a physical stop and does not lock the load without air pressure.
At 0.9MPa, the push force increases to 7068N.
