About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX70-10
The AirTAC SAIJ160X70-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 10 mm. This creates a usable stroke window of 60 to 70 mm, letting you dial in the exact end position at commissioning without adding external stops. It delivers substantial thrust, providing 9425 N of pull force at 0.5 MPa and reaching 18095 N at 0.9 MPa.
This large-bore unit is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and carries a robust M36x2 rod thread. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. It uses PT tapered port threads (G3/4) and features variable air cushions at both ends to manage the kinetic energy of its 40 mm diameter rod.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX70-10 Is Used
Heavy Press Tuning
Dial in the exact 60-70 mm travel window during heavy press commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adapt the end-stop position for varying product sizes on a high-thrust assembly line.
Machine Setup
Fine-tune the retract end position during initial machine setup to avoid mechanical collisions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX70-10 the Right Cylinder?
Choose this 160 mm bore cylinder when your application requires heavy pull force (9425 N at 0.5 MPa) and on-the-fly end-position tuning. If you need slightly less force, stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 cylinder, specify: 160 mm bore, 70 mm stroke, 10 mm adjustment, PT G3/4 port, and your required mounting style from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ160BX70-10 FAQ
At a 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw lets you shorten the nominal 70 mm stroke by up to 10 mm. This provides a usable travel window of 60 to 70 mm, allowing precise end-position tuning without replacing the cylinder.
