About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-50S
The AirTAC SAIJ160X230-50-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stopper that allows you to trim the nominal 230 mm stroke back by up to 50 mm. This yields a highly flexible 180 to 230 mm usable travel window, letting you dial in exact end positions during commissioning without adding bulky external stops. It delivers robust thrust, pushing with 14074 N at 0.7 MPa.
This SKU is built with a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing via AirTAC CMSE reed or DMSE solid-state switches. The 40 mm rod and M36x2 thread handle significant side loads, though long travel still demands an external guide. The mounting set is reduced to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB and rear pivot options.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-50S Is Used
Press Tuning
Dial in the exact 180 to 230 mm end position during machine commissioning to accommodate varying material thicknesses without re-mounting the actuator.
Product Changeover
Rapidly adjust the stroke stop on a packaging line when switching to a different carton size, using the 50 mm trim window to set new retraction points.
Heavy Material Handling
Leverage the 14074 N push force at 0.7 MPa to move heavy pallets or fixtures, relying on the SUS304 rod for durability in harsh environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-50S the Right Cylinder?
Select this 160 mm bore when an application requires heavy thrust around 14000 N at 0.7 MPa, but you need leeway in the final end-of-stroke position. If you need less force, the 125 mm bore provides 8590 N at 0.7 MPa; stepping up to the 200 mm bore yields 21991 N. The adjustable stroke is chosen over a fixed SAI cylinder when machine setups require frequent product changeovers or fine-tuning without physically swapping the actuator.
When matching this for an ISO 15552 replacement, verify the 160 mm bore, 230 mm stroke, 50 mm adjustment range, PT tapered port threads, and the -S magnet. Because the stroke is 230 mm, ensure your mounting arrangement supports the rod adequately to prevent side-load wear. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold a load without live air. For true load-holding, use an external rod lock or an AirTAC SAIL or BSAI clamp-lock variant.
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 SAIJ160BX230-50S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. It can deliver up to 18095 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 230 mm down to as little as 180 mm. This provides a 50 mm setup window for fine-tuning the retract position without replacing the cylinder.
