Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-50
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 135mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-50
The AirTAC SAIJ160X135-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates an 85-135mm usable travel window. Delivering 10053N of pull force at 0.5MPa, this carbon-steel rod unit handles heavy loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
A built-in rear stopper screw allows you to fine-tune the end position at commissioning without adding external stops. The adjustment mechanism acts purely as a travel stop and does not hold the load without live air pressure. For position holding without compressed air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-50 Is Used
Heavy Press Tuning
Dial in the exact 85-135mm travel during machine commissioning to set precise pressing forces on heavy assemblies.
Product Changeover
Quickly adjust the retract stop to accommodate different material thicknesses on a production line without swapping cylinders.
Variable End Stops
Use the rear adjustment screw to set specific retraction depths for multi-tiered automated ejection systems.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-50 the Right Cylinder?
Choose this 160mm bore when 125mm bore cylinders (providing 6136N pull at 0.5MPa) lack the necessary force. The PT G3/4 tapered port and M36x2 rod thread provide robust fluid flow and high side-load resistance. Because the 135mm stroke is relatively short for this bore, external guiding is less critical than on longer strokes.
Select this adjustable model over a fixed SAI cylinder when your machine setup requires variable end-stops for product changeovers. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. Without a magnet, it does not support CMSE or DMSE sensors.
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 SAIJ160X135-50 FAQ
At 0.5MPa it provides 10053N pull and 14074N push, scaling up to 18095N push at 0.9MPa.
The rear adjuster screw lets you shorten the 135mm nominal stroke by up to 50mm, giving an effective travel window of 85-135mm for precise end-position tuning.
