About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-100
The AirTAC SAIJ160X115-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 14074N of push force at 0.7 MPa. It features a standard carbon steel rod and a PT tapered port thread. By integrating an external adjusting stopper, this cylinder provides a usable travel window of 15-115 mm, allowing you to dial back the nominal 115 mm stroke by up to 100 mm.
This wide adjustment range is perfect for product changeovers, letting you fine-tune end positions at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and while this unit lacks a magnet, adding the -S option enables compatibility with AirTAC CMSE reed and DMSE electronic solid-state sensors.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-100 Is Used
Variable End-Stop Tuning
Dial in the exact clamping distance on heavy fixtures by adjusting the rear stopper from 15 to 115 mm, avoiding the need to physically swap cylinders when product dimensions change.
Machine Changeover
Rapidly reconfigure production lines for new part sizes by turning the external adjuster, fine-tuning the retract position without bolting on secondary external stops.
Heavy Press Fitting
Leverage the 14074N push force to seat large bearings, using the adjustable travel window to precisely control insertion depth and prevent over-travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-100 the Right Cylinder?
Choose this 160 mm bore when you need heavy thrust that a 125 mm bore cannot provide, as the 125 mm only yields 8590N at 0.7 MPa compared to the 14074N here. The adjustable stroke is selected over a fixed SAI model when your setup requires variable end-stops or commissioning fine-tuning. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-air load holding, consider an external rod lock or the AirTAC SAIL lock cylinder.
To match this ISO 15552 interchangeable cylinder exactly, specify the 160 mm bore, 115 mm stroke, 100 mm adjustment, PT port thread, and your required mounting style from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Although the stroke is under 300 mm, the 40 mm rod diameter and M36x2 thread provide excellent rigidity, but any long unsupported loads should still use an external guide.
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 SAIJ160X115-100 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074N of push force and 9425N of pull force. It can reach a maximum of 18095N push force at 0.9 MPa.
The rear adjusting screw acts as a mechanical stop that lets you trim the effective travel back by up to 100 mm. This creates a usable stroke window of 15 to 115 mm, allowing you to set the exact retract end-position during commissioning without changing the cylinder.
