Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-30
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 290mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-30
The AirTAC SAIJ160X290-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 260-290 mm window. Built with a SUS304 stainless steel rod and PT tapered ports, it provides 10053 N of pull force at 0.5 MPa and reaches a maximum of 2050 kgf at 1.0 MPa. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This adjustable model lets you dial in the retract end-position during commissioning without swapping out the entire cylinder or adding external stops. The 30 mm adjustment screw acts purely as a travel stop working alongside the 50 mm air cushions to decelerate the load; it does not hold the position without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-30 Is Used
Heavy Press Tuning
Dial in the exact 260-290 mm retract stop during machine commissioning to accommodate varying material thicknesses without adding external physical blocks.
Product Changeover
Quickly adjust the end-of-stroke position on a heavy assembly line when switching product sizes, leveraging the 30 mm trim window to save setup time.
Long-Travel Positioning
Handle substantial 10053 N pull loads over a 290 mm stroke, using the 50 mm air cushions and rear stopper to safely decelerate heavy moving tooling.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-30 the Right Cylinder?
Selecting this 160 mm bore is ideal when you need heavy thrust between the 125 mm class (5734 N pull at 0.5 MPa) and the 200 mm class (15080 N pull). The SAIJ160X290-30 is chosen over a fixed SAI cylinder when a machine requires variable end-stops to accommodate product changeovers or precise setup tuning. To replace an ISO 15552 cylinder, match the 160 mm bore, 290 mm stroke, 30 mm adjustment, PT G3/4 ports, and standard mounting interface.
Because the 290 mm stroke is substantial, the 40 mm diameter SUS304 rod provides robust support, but an external guide is still recommended to prevent excessive side-loading on long unsupported travels. The mounting hardware is limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Operating speed is capped at 30-500 mm/s for this bore size.

- ✓ 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 SAIJ160BX290-30 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force at 0.7 MPa. The maximum thrust is 2050 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 290 mm stroke by up to 30 mm, creating a usable travel window of 260-290 mm. The adjuster acts as a mechanical stop to fine-tune the end position and does not function as a lock or brake to hold the load without air pressure.
