About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-20
The AirTAC SAIJ160X85-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 65 to 85 mm. It delivers massive thrust, generating 18095 N of push force at 0.9 MPa, making it well-suited for heavy-duty positioning tasks.
This variant incorporates an SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for the direct mounting of CMSE reed and DMSE electronic sensors if position feedback is later required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-20 Is Used
Heavy Pressing Operations
Dials in the exact 65 to 85 mm travel distance needed for high-force pressing or forming tasks during machine setup.
Product Changeover
Allows operators to quickly adjust the end-stop distance on a packaging line when processing different material thicknesses.
Automated Assembly
Provides a robust 18095 N push force at 0.9 MPa for driving heavy components, with fine-tuning available at the rear stopper.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX85-20 the Right Cylinder?
Choose this 160 mm bore when you need significantly more power than the 100 mm bore offers, which provides 7068 N of push force at 0.9 MPa. The adjustable rear stopper allows you to fine-tune the exact end position during commissioning or product changeover without swapping out the entire cylinder or adding external physical stops.
When ordering, specify the 160 mm bore, 85 mm stroke, 20 mm adjustment range, PT port thread, and SUS420J2 rod material. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.
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.
