About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-75S
The AirTAC SAIJ160X900-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 900 mm nominal stroke to a precise 825-900 mm window. It delivers substantial thrust, generating 10053 N of pull force at 0.5 MPa and up to 18095 N of push force at 0.9 MPa.
This configuration includes a SUS304 stainless steel rod for superior corrosion resistance and an integrated magnet (-S) for position sensing with CMSE reed or DMSE electronic switches. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions, and the PT tapered ports ensure a tight pneumatic seal.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-75S Is Used
Large-Part Machining Changeover
Dial in the 825-900 mm travel window during machining line changeovers to accommodate different raw casting lengths without replacing the actuator.
Extended-Reach Diverting
Adjusts the retract position on a long-stroke conveyor sorting arm to handle varying pallet depths on the fly.
Heavy Assembly Press Setup
Provides a 10053 N pull force for heavy assembly operations while allowing operators to fine-tune the end-of-stroke position during initial equipment commissioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-75S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end-stops or product changeover flexibility without physically swapping out a fixed-stroke SAI cylinder. The 900 mm stroke is fully standard for the 160 mm bore, but the extended length means an external guide is strongly recommended to prevent excessive side-loading on the rod.
If your force requirements are lower, stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series. To match this ISO 15552 replacement exactly, specify: 160 mm bore, 900 mm stroke, 75 mm adjustment, PT G3/4 ports, and the -S magnet.
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 SAIJ160 Adjustable Cylinder SAIJ160BX900-75S FAQ
The rear adjuster screw acts as an external stopper, allowing you to shorten the effective stroke by up to 75 mm. This creates a usable travel window of 825-900 mm, providing fine end-position tuning at commissioning without adding external stops.
At 0.5 MPa, it provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
