About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-20
The AirTAC SAIJ160X250-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 230 to 250 mm window. It delivers robust thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa, making it suitable for heavy-duty handling. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches.
This specific SKU is configured with a SUS304 stainless steel piston rod for superior corrosion resistance and uses PT tapered port threads. The rear adjuster acts purely as a mechanical stop to dial in the retract end position during commissioning or product changeover without adding external stops. It is not a locking device, so live air pressure is required to hold the load in place.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-20 Is Used
Heavy Press Fit Tuning
Dial in the exact 230-250 mm retract stop during heavy press or assembly operations to compensate for material thickness variations without recalculating fixed stop lengths.
Product Changeover Setup
Quickly adjust the end-of-stroke position on packaging or handling machinery when switching between product sizes, using the rear screw to trim up to 20 mm of travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-20 the Right Cylinder?
The adjustable 230-250 mm travel window is ideal for machinery that requires precise end-position tuning during setup or when accommodating slight product size variations on a line. Because the rear adjuster only sets the travel end and the air cushions manage deceleration, you must maintain live air pressure to hold a load; for true fail-safe load holding without pressure, select an AirTAC SAIL or BSAI cylinder. As a dimensionally interchangeable ISO 15552 cylinder, ensure your replacement matches this 160 mm bore, 250 mm stroke, 20 mm adjustment, PT ports, and SUS304 rod. Mounting options include the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160BX250-20 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 250 mm stroke by up to 20 mm, creating a usable travel window of 230 to 250 mm. It sets the end position but does not lock the load, so continuous air pressure is required to hold position.
