About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-50S
The AirTAC SAIJ160X290-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 290 mm travel back by up to 50 mm, yielding a usable 240-290 mm end-position window. The extruded aluminum barrel includes sensor grooves on both sides for direct CMSE or DMSE switch mounting.
This variant uses a SUS304 stainless steel rod for corrosion resistance and PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position during commissioning or product changeover. It is not a lock; the cylinder cannot hold a load without live air pressure, so applications requiring true load-holding should use an external rod lock or a SAIL cylinder.

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 SAIJ160BX290-50S Is Used
Variable End-Stop Forming
Dial in the exact 240-290 mm retract position during machine setup to accommodate different metal panel lengths without changing out physical spacers.
Product Changeover Press
Quickly adjust the rear stopper on a multi-model assembly line to switch between component sizes, reducing downtime between production runs.
Long-Stroke Alignment
Leverage the 290 mm travel for large-format material handling, using the adjuster to fine-tune the final resting position for precise placement.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-50S the Right Cylinder?
The adjustable 240-290 mm travel window is ideal for machinery that processes multiple product sizes, allowing operators to dial in the exact end-stop without swapping the cylinder or adding external physical stops. To match this exact replacement, specify a 160 mm bore, 290 mm stroke, 50 mm adjustment, PT ports, SUS304 rod, and the -S magnet.
Because the 290 mm stroke creates a long unsupported rod extension, an external guide rail is strongly recommended to prevent excessive side-loading and premature seal wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR brackets.
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 SAIJ160BX290-50S FAQ
It operates between 0.15 and 1.0 MPa, runs at speeds of 30-500 mm/s, and features a 50 mm stroke adjustment range.
The rear adjuster screw lets you shorten the effective travel from 290 mm down to 240 mm. This mechanical stop fine-tunes the end position during commissioning but does not lock the load without continuous air pressure.
