About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX25-20
The AirTAC SAIJ160X25-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 5 to 25 mm, allowing operators to fine-tune the retract end-position during commissioning without adding external stops. This heavy-duty bore generates 10053 N of pull force at 0.5 MPa, making it suited for high-thrust short-stroke tasks.
Equipped with a SUS304 stainless steel rod (option B) and PT tapered ports, it resists corrosion in demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for mounting reed CMSE or solid-state DMSE switches. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX25-20 Is Used
Short-Stroke Pressing
Provides 10053 N of pull force at 0.5 MPa for high-thrust pressing, staking, and riveting operations within a tight 5-25 mm travel window.
Machine Changeovers
The 20 mm rear adjustment screw allows operators to dial in new end-stops for different product sizes on a shared line without swapping hardware.
Heavy Clamping Fixtures
The SUS304 stainless steel rod withstands harsh industrial fluids while delivering reliable, high-force clamping on large machined components.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX25-20 the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore (2268 N pull at 0.5 MPa) is insufficient for your clamping or pressing requirements. The adjustable 5-25 mm window is ideal for product size changeovers on a line, providing variable end-stops without replacing the cylinder. For load-holding without continuous air, select a SAIL or BSAI series cylinder instead, as the SAIJ adjuster is only a stop. To match this ISO 15552 replacement exactly, specify the 160 mm bore, 25 mm stroke, 20 mm adjustment, PT ports, and no magnet.
Because the 25 mm stroke is very short, side-loading is minimal, but always ensure the M36x2 rod thread is properly aligned to prevent seal wear.

- ✓ 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 SAIJ160BX25-20 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 20 mm. This creates a usable travel window of 5 to 25 mm, enabling precise end-position tuning at commissioning without external stops.
At 0.5 MPa operating pressure, it provides 10053 N of pull force and 14074 N of push force. It can deliver up to 2050 kgf at its maximum 1.0 MPa pressure rating.
