About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-30S
The AirTAC SAIJ80X190-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 30 mm of travel reduction. This creates a usable stroke window of 160 to 190 mm, enabling precise end-position tuning during commissioning without adding external stops. It delivers a robust 2513 N pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
Equipped with a standard -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side barrel grooves. The 25 mm carbon steel piston rod and M20x1.5 thread provide high structural rigidity, while the PT tapered port threads ensure a reliable pneumatic seal. The integrated adjustable air cushions at both ends manage end-of-stroke deceleration effectively.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-30S Is Used
Machine Changeover
Dial in the 160-190 mm travel window during product size transitions to set new retract endpoints without replacing hardware.
Sensor Positioning
Leverage the -S magnet with CMSE reed or DMSE electronic switches in the dual barrel grooves for precise end-of-stroke detection.
Heavy Clamping
Apply the 2513 N pull force at 0.5 MPa to secure heavy workpieces, using the rear stop to fine-tune the clamp position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-30S the Right Cylinder?
Choose this adjustable-stroke model when a process requires variable end-stops or frequent product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If your application demands less force, stepping down to a 63 mm bore yields a 1402 N pull at 0.5 MPa; stepping up to a 100 mm bore provides 3681 N. Remember that the rear adjuster acts solely as a mechanical stop and does not hold the load without live air pressure. For load-holding requirements, consider an SAIL or BSAI series cylinder instead. Because this is a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 units of the same bore and stroke. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80X190-30S FAQ
A rear adjusting screw allows you to shorten the nominal 190 mm stroke by up to 30 mm, providing an effective travel range of 160 to 190 mm. This stopper sets the retract end position but does not lock the load without live air pressure.
At a 0.5 MPa operating pressure, it generates 2513 N of pull force and 3518 N of push force. The cylinder operates efficiently at speeds between 30 and 800 mm/s.
