About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-50S
The AirTAC SAIJ160X195-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you dial back the nominal 195 mm travel by up to 50 mm, creating a usable 145-195 mm end-position window. It delivers robust thrust, pushing 10053 N and pulling 9425 N at 0.5 MPa, making it suitable for heavy-duty handling. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for position detection.
Because the adjuster acts as a physical stop at the retract end, you can fine-tune the travel during commissioning or product changeovers without adding external stops or swapping the cylinder. It uses a PT (tapered) G3/4 port and a 40 mm carbon steel rod with an M36x2 thread. The rear adjuster and variable air cushions at both ends manage end-of-stroke deceleration, but neither will hold a load without live air pressure; for true load-holding, consider an external rod lock or the AirTAC SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-50S Is Used
Heavy Pressing
Apply up to 18095 N of push force at 0.9 MPa for heavy-duty assembly or forming tasks, with precise end-position tuning.
Changeover Tuning
Dial in the 145-195 mm travel window during product size changeovers without machining new external stopper blocks.
Machine Setup
Fine-tune the retract end-stop during initial commissioning to perfectly synchronize heavy actuators on the line.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X195-50S the Right Cylinder?
Choose this 160 mm bore when you need high force (10053 N pull at 0.5 MPa) that exceeds the 6136 N pull of a 125 mm bore, but do not require the massive 15708 N push of a 200 mm unit. The adjustable 145-195 mm travel window is ideal for machines requiring variable end-stops during setup or product-size changeovers, replacing fixed-stroke SAI cylinders when exact positioning needs field tuning. As a dimensionally interchangeable ISO 15552 cylinder, it matches replacements by bore, 195 mm stroke, 50 mm adjustment, G3/4 PT port, and -S magnet. It operates at 30-500 mm/s and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAIJ160X195-50S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the 195 mm nominal stroke by up to 50 mm, providing a usable travel window of 145 to 195 mm for fine-tuning end positions.
At 0.5 MPa it provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa operating pressure, it delivers up to 2050 kgf of push force.
