About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-50
The AirTAC SAIJ160X85-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 35 to 85 mm, allowing you to dial back the 85 mm nominal stroke by up to 50 mm during commissioning. This bore delivers 10053 N of push force at 0.5 MPa and uses a G3/4 port for high-volume airflow.
Built with a SUS304 stainless steel rod (option B), it handles corrosive environments better than standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches, though this specific SKU is non-magnetic and requires adding an -S magnet to enable them. The rear stopper sets the end position but does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-50 Is Used
Machine Changeover
Fine-tune the 35-85 mm travel window during product size changes on a packaging line without adding external stopper blocks.
End-Stop Calibration
Precisely set the retract end position during commissioning to dial in exact clamping or pressing distances.
High-Force Positioning
Move heavy jigs using 10053 N of thrust while retaining the flexibility to shorten the stroke by up to 50 mm.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-50 the Right Cylinder?
Choose this 160 mm bore when your application requires 10053 N of push force at 0.5 MPa, or up to 18095 N at 0.9 MPa. If you need less force, stepping down to a 125 mm bore yields 6136 N at 0.5 MPa, while stepping up to a 200 mm bore provides 15708 N. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers without swapping hardware.
When matching ISO 15552 dimensions, specify a 160 mm bore, 85 mm stroke, 50 mm adjustment, PT tapered G3/4 port, and SUS304 rod material. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. For load-holding without live air, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the adjuster.
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 SAIJ160BX85-50 FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster acts as a travel stop, allowing you to trim the 85 mm nominal stroke back by up to 50 mm, creating a usable 35-85 mm window. It decelerates the end of travel but does not lock the load without live air.
