About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-20S
The AirTAC SAIJ160X300-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 280 to 300 mm. This makes it well-suited for heavy-duty manipulation tasks requiring precise end-position calibration during commissioning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and it uses a PT tapered G3/4 port. It operates at speeds of 30-500 mm/s and includes variable air cushions at both ends to manage deceleration.

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 SAIJ160BX300-20S Is Used
Heavy Press Tuning
Dial in the exact 280-300mm end-stop during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the retract position on automated lines when switching product sizes, using the rear screw to set new parameters.
Large Assembly Calibration
Fine-tune the end position on large assembly stations to ensure perfect alignment of heavy components before final locking.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX300-20S the Right Cylinder?
An adjustable stroke is favored over a fixed SAI cylinder when you need to dial in the exact end-stop during machine setup or product changeover without adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for load-holding without pressure, consider the SAIL or BSAI series. At 300 mm stroke, the long unsupported travel requires an external guide to prevent side-load damage to the rod. This unit is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
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 SAIJ160BX300-20S FAQ
The rear adjuster screw allows you to shorten the nominal 300 mm stroke by up to 20 mm, providing a usable travel window of 280 to 300 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
