About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-100
The AirTAC SAIJ160X210-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to shorten the effective travel. With a 210 mm nominal stroke and a 100 mm adjustment range, the usable travel window spans 110 to 210 mm. This bore size provides immense thrust, yielding 14074 N push and 9425 N pull at 0.7 MPa.
Configured with a SUS304 stainless steel rod and PT tapered ports, this model resists corrosion while maintaining a robust 40 mm rod diameter. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. If you need position holding without live air pressure, this cylinder is not a lock; consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-100 Is Used
Heavy Pressing
Apply up to 18095 N of push force at 0.9 MPa for stamping or forming operations.
Product Changeover
Dial the travel back by up to 100 mm to accommodate different part lengths on the fly.
Machine Setup
Fine-tune the retract end-position during commissioning without external stoppers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-100 the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore (3518 N push at 0.7 MPa) is insufficient but a 200 mm bore is excessive. The 100 mm adjustment range is ideal for product changeovers, letting you dial back the end position from 210 mm to 110 mm without adding external stops or swapping the cylinder. For fixed-position tasks, the standard SAI series is simpler, but the SAIJ excels in variable end-stop setups.
To replace an ISO 15552 cylinder, match the 160 mm bore, 210 mm stroke, 100 mm adjustment, PT G3/4 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. Note that SAIJ omits FB, CA, CB, and CR mounts. Because the stroke is over 300 mm, use an external guide to prevent side-load damage to the rod.
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 SAIJ160BX210-100 FAQ
At 0.5 MPa it provides 10053 N push and 9425 N pull. At 0.7 MPa the push force is 14074 N, and it reaches 18095 N at 0.9 MPa.
A rear stopper screw lets you trim the nominal 210 mm stroke back by up to 100 mm, creating a usable travel window of 110 to 210 mm. It acts as a travel stop, not a lock.
