About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X130-50S
The AirTAC SAIJ160X130-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits fine-tuning of the retract end position. With a 130 mm nominal stroke and a 50 mm adjustment range, it provides a usable travel window of 80-130 mm, allowing you to set the exact end-stop without adding external stops. It delivers a robust thrust, generating 14074 N of push force and 9425 N of pull force at a 0.7 MPa operating pressure.
This 160 mm bore profile cylinder incorporates a carbon steel piston rod and uses PT (tapered) G3/4 porting. Because it includes the -S magnet option, it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state sensors that seat directly into the dual-side extruded aluminum barrel grooves. The rear adjuster acts purely as a travel stop for deceleration and positioning; it is not a locking mechanism and will not hold a load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X130-50S Is Used
Product Changeovers
Dial in the 80-130 mm travel window on the fly during packaging line format changes, avoiding physical cylinder swaps.
End-Position Tuning
Use the rear stopper to precisely set the retract position during machine commissioning without adding external mechanical stops.
Adjustable Ejection
Vary the ejection distance of heavy parts dynamically, relying on the 18095 N push force at 0.9 MPa to move the load.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X130-50S the Right Cylinder?
Choose this adjustable-stroke model when your application requires variable end-position tuning during commissioning or frequent product-size changeovers, rather than relying on a fixed-stroke SAI cylinder. If your thrust requirements are lower, stepping down to a 125 mm bore yields 8590 N push force at 0.5 MPa; conversely, moving up to a 200 mm bore provides 21991 N at 0.7 MPa. To replace an ISO 15552 cylinder, match the 160 mm bore, 130 mm stroke, 50 mm adjustment, G3/4 PT port, and the -S magnet requirement.
The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets. For load-holding without live air pressure, consider the SAIL pneumatic lock or BSAI clamp-lock variants instead of relying on this rear stopper. The 40 mm diameter rod and M36x2 thread provide high structural rigidity, though any application approaching the maximum stroke limit should still use an external guide to manage side loads.
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 SAIJ160X130-50S FAQ
At 0.7 MPa it provides 14074 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster allows you to shorten the 130 mm nominal stroke by up to 50 mm, creating a usable travel window of 80-130 mm. It functions as a mechanical stop for end-position tuning and does not lock the load without live air.
