About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X50-30
The AirTAC SAIJ160X50-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 9425N pull force at 0.5 MPa and allows you to trim the nominal 50mm stroke back by up to 30mm, creating a 20-50mm usable travel window for precise end-position tuning at commissioning.
This 160mm bore unit integrates a robust 40mm carbon steel rod and an M36x2 thread to handle high side loads. It uses a PT tapered G3/4 port and relies on a 50mm air cushion at both ends to decelerate the moving load. The rear stopper sets the travel end but does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X50-30 Is Used
Machine Setup Tuning
Dial in the exact 20-50mm retract position during commissioning to perfect a heavy pressing operation without machining external stopper blocks.
Product Changeover
Quickly adjust the end-stop on a high-force assembly line when switching to a new product variant that requires a slightly shorter travel distance.
Fixture Positioning
Fine-tune the clamping reach on large fixtures using the 9425N pull force, relying on the 40mm carbon steel rod for rigid side-load resistance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X50-30 the Right Cylinder?
Select this adjustable model over a fixed SAI cylinder when your setup requires variable retract end-stops or frequent product-size changeovers without swapping the physical cylinder. If your machine needs true load-holding without continuous air pressure, step over to the SAIL or BSAI locking series instead, as the SAIJ adjuster is strictly a stop.
To match this ISO 15552 interchangeable cylinder for replacement, verify the 160mm bore, 50mm stroke, 30mm adjustment range, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the speed range is 30-500mm/s, ensure your external guide handles the heavy 40mm rod dynamics.

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 SAIJ160X50-30 FAQ
The rear adjuster screw lets you shorten the 50mm nominal stroke by up to 30mm, providing a usable travel window of 20-50mm. It acts as a mechanical stop to fine-tune the retract position and works alongside the 50mm air cushion for deceleration.
At 0.5 MPa, it generates a push force of 10053N and a pull force of 9425N. At the maximum operating pressure of 1.0 MPa, the push force reaches 15708N.
