About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-30S
The AirTAC SAIJ160X135-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. With a nominal 135 mm stroke and a 30 mm adjustment range, it provides a usable travel window between 105 and 135 mm. This built-in adjustability allows for precise commissioning without swapping the cylinder or adding external stops.
In the 160 mm bore class, this cylinder delivers substantial thrust, generating 10053 N of pull force at 0.5 MPa and 14074 N of push force at 0.7 MPa. It includes a magnet for position sensing, compatible with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel features sensor grooves on both sides, and the standard carbon steel rod carries an M36x2 thread, providing a robust interface for high-load tasks.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-30S Is Used
Heavy Press Tuning
Dial in the exact 105-135 mm travel window during heavy press commissioning to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the retract end-position by up to 30 mm on automated lines when switching between different product sizes.
Assembly Line End-Stops
Use the rear stopper to fine-tune the final end-of-stroke position on heavy assembly stations, ensuring perfect alignment without external mechanical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-30S the Right Cylinder?
Choose this 160 mm bore model when your application requires heavy force output combined with variable end-stops for product changeover. If your setup needs less force, stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa, whereas moving up to a 200 mm bore provides 15080 N of pull force. The SAIJ160X135-30-S is dimensionally interchangeable per ISO 15552 mounting-interface dimensions, features PT tapered port threads, and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
Because the 135 mm stroke is relatively short for this large bore, side-load risks are minimal, but external guides are still recommended for heavy loads. Remember that the rear adjuster acts as a travel stop to decelerate the piston, not a lock; this cylinder will not hold its load without live air. For true load-holding without pressure, consider the SAIL or BSAI series instead.
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 SAIJ160X135-30S FAQ
At 0.5 MPa, it provides 10053 N of pull force and 14074 N of push force at 0.7 MPa. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm. This creates a usable travel window of 105 to 135 mm, allowing precise end-position tuning at commissioning without replacing the cylinder.
