About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-40S
The AirTAC SAIJ160X115-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. With a nominal 115 mm stroke and a 40 mm adjustment range, it provides a usable travel window of 75 to 115 mm. This allows precise end-position tuning at commissioning without adding external stops. The 160 mm bore delivers 10053 N of thrust at 0.5 MPa, making it suited for heavy-duty positioning.
This model includes a magnet for CMSE reed and DMSE electronic sensors, which fit into the extruded aluminum barrel's dual sensor grooves. It uses a PT tapered port and a robust 40 mm carbon steel rod with an M36x2 thread. The rear adjuster acts strictly as a travel stop for deceleration, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-40S Is Used
Heavy Press Tuning
Dial in the exact 75-115 mm travel window during heavy press setup to accommodate varying material thicknesses without changing cylinders.
Product Changeover
Quickly adjust the end-stop position on automated assembly lines when switching between different product sizes.
Sensor-Ready Positioning
Leverage the built-in magnet and dual sensor grooves for CMSE or DMSE switches to confirm end positions in automated workflows.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-40S the Right Cylinder?
Choose this 160 mm bore when you need high thrust between the 125 mm bore (6136 N at 0.5 MPa) and the 200 mm bore (15708 N). The adjustable 75-115 mm window is ideal for product changeovers where exact end-of-stroke positioning varies, eliminating the need to swap a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead of relying on this adjuster.
To replace an ISO 15552 cylinder, match the 160 mm bore, 115 mm stroke, 40 mm adjustment, PT port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 40 mm rod and M36x2 thread handle high side loads, ensure proper external guiding for optimal longevity.
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 SAIJ160X115-40S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053 N of push force and 9425 N of pull force. It can reach up to 14074 N push force at 0.7 MPa.
The rear adjuster screw lets you shorten the effective travel from the 115 mm nominal stroke down to 75 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
