About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-20
The AirTAC SAIJ160X85-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 65 to 85 mm usable travel window. Delivering 10053 N of push force at 0.5 MPa, this heavy-duty actuator handles demanding positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback integration.
Equipped with a SUS304 stainless steel rod and a PT tapered G3/4 port, this unit resists corrosion while providing high flow capacity. The rear adjustment screw acts strictly as a mechanical stop to fine-tune the retract end position at commissioning; it does not hold the load without live air pressure. Variable air cushions at both ends absorb kinetic energy, and the operating speed ranges from 30 to 500 mm/s.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-20 Is Used
Heavy Pressing Operations
Provides 10053 N of thrust for assembling large components, using the 20 mm rear adjuster to precisely tune the pressing depth without reprogramming the motion controller.
Product Changeover
Quickly adapts the retract end-stop by up to 20 mm on a packaging line when switching to a different product size, reducing setup downtime.
Industrial Material Handling
Moves heavy pallets or fixtures using the robust 160 mm bore, relying on the SUS304 rod for durability in demanding manufacturing environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-20 the Right Cylinder?
Select this 160 mm bore actuator when an application requires substantial thrust—10053 N push and 9425 N pull at 0.5 MPa—combined with exact end-position tuning. If your force requirements are lower, stepping down to a 125 mm bore yields 6136 N push force, whereas moving up to a 200 mm bore provides 15708 N. The 20 mm adjustment range is ideal for dialing in the retract position during machine setup or product changeover without swapping cylinders or adding external stops. Because the 85 mm nominal stroke is short, side-load risks are minimal, but an external guide is always recommended for heavy loads. For applications that must hold position without live air, consider the SAIL locking cylinder or BSAI clamp-lock instead of relying on this adjuster. To match this ISO 15552 footprint, specify the 160 mm bore, 85 mm stroke, 20 mm adjustment, PT G3/4 port, SUS304 rod, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting.

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 SAIJ160BX85-20 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. The operating speed range is 30 to 500 mm/s.
The rear adjuster screw mechanically limits the piston travel, creating a 65 to 85 mm usable stroke window. It allows you to fine-tune the end position during setup but acts only as a stop; it does not lock or hold the load without continuous air pressure.
