About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-50
The AirTAC SAIJ160X190-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 190 mm travel by up to 50 mm. This yields a usable 140-190 mm end-position window, enabling precise fine-tuning during commissioning or product changeovers without swapping out the physical cylinder. As an extruded aluminum profile cylinder, it is dimensionally interchangeable with ISO 15552 cylinders and features sensor grooves on both sides for flexible switch mounting.
It features a robust 40 mm SUS304 stainless steel rod with an M36x2 thread, providing excellent corrosion resistance and high side-load capacity. The unit incorporates adjustable air cushions at both ends (50 mm cushion stroke) to manage heavy kinetic energy, operating at speeds between 30-500 mm/s.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-50 Is Used
Product Changeover
Dial in the 140-190 mm travel window during format size changes on a packaging line without physically replacing the cylinder or adding external shims.
Machine Setup
Fine-tune the end-of-stroke retract position during initial machine commissioning to perfectly time heavy material handling sequences.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX190-50 the Right Cylinder?
The SAIJ160X190-50 is chosen over a fixed-stroke SAI when a machine handles varying product sizes, as the 50 mm rear adjusting screw acts as a mechanical stop to set the exact retract distance. Note that this adjuster and the air cushions only decelerate the travel end; they do not hold the load without live air. For dead-load holding, an external pilot-operated check valve, a SAIL pneumatic lock, or a BSAI clamp-lock cylinder is required.
To match this exact ISO 15552 replacement configuration, confirm a 160 mm bore, 190 mm nominal stroke with a 50 mm adjustment range, PT tapered port threads, and the SUS304 (code B) rod material. Because the 190 mm stroke is under the 300 mm threshold, side-load stress is moderate, though the heavy 40 mm rod still handles typical cantilever loads well. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR styles.
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 SAIJ160BX190-50 FAQ
The rear adjuster screw acts as a mechanical stop that lets you trim the effective stroke back from the 190 mm nominal length, creating a usable travel window of 140-190 mm. It only sets the end position and does not lock the load without continuous air pressure.
