About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-50S
The AirTAC SAIJ200X165-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the 165 mm nominal travel by up to 50 mm. This creates a highly versatile 115-165 mm usable stroke window, allowing precise end-position tuning at commissioning or during product changeovers without swapping the hardware. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, scaling up to 3204 kgf at 1.0 MPa.
This unit features a SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel incorporates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid supply is routed through PT G3/4 tapered ports, and the design includes variable air cushions at both ends to manage kinetic energy during operation.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-50S Is Used
Heavy Press Tuning
Fine-tune the exact end-of-stroke position for a 1500+ kgf pressing operation within the 115-165 mm window without adding external mechanical stops.
Product Changeover
Quickly adapt the cylinder's effective travel on a heavy assembly line when switching to a new product variant that requires a slightly shorter stroke.
Large Mold Handling
Precisely dial in the retraction point for heavy mold or fixture handling, ensuring perfect alignment before the final clamping sequence begins.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-50S the Right Cylinder?
Selecting this 200 mm bore size is appropriate when your application requires extremely high force, as stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops to accommodate slight mechanical differences or fine-tune a heavy load's resting position. For any made-to-order stroke of 300 mm or more on this bore, you must use an external guide to manage side loads, as even the robust 40 mm rod and M36x2 thread cannot support high cantilevered weights indefinitely.
When matching this for an ISO 15552 interchange, verify the 200 mm bore, 165 mm stroke, 50 mm adjustment, PT G3/4 port, and the -S magnet requirement. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some other series. Remember that the rear adjuster acts purely as a travel stop; it does not hold the load without live air. For true load-holding without pressure, use an external rod lock, a pilot-operated check valve, or the AirTAC SAIL or BSAI cylinder series.
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 SAIJ200 Adjustable Cylinder SAIJ200AX165-50S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw lets you shorten the 165 mm nominal stroke by up to 50 mm, creating a usable travel window of 115-165 mm. The adjuster acts as a mechanical stop and works with the air cushion to decelerate the load, but it does not lock the position without live air pressure.
