About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-75S
The AirTAC SAIJ200X550-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 475 to 550 mm. It delivers substantial thrust, generating 21991 N push force at 0.7 MPa, making it suitable for heavy-duty industrial tasks. The PT tapered ports and standard carbon steel rod ensure reliable performance under high stress.
This model includes a magnet (-S) for seamless integration with AirTAC CMSE reed and DMSE electronic sensors, which mount directly into the dual-side barrel grooves. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract position during commissioning. It is not a locking mechanism, so the cylinder relies on live air to maintain its load, requiring an external guide for the long 550 mm stroke to prevent rod side-loading.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-75S Is Used
Heavy Press Tuning
Dial in the exact 475-550 mm pressing depth during machine setup to accommodate varying material thicknesses without replacing the cylinder.
Product Changeover
Adjust the retract stopper on the fly to handle different product sizes moving down a heavy-duty packaging line.
Large Assembly Jigs
Set precise end-positions for massive components during commissioning, using the 75 mm adjustment to perfect the tooling stroke.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X550-75S the Right Cylinder?
Choose this 200 mm bore cylinder when an application demands up to 21991 N of push force at 0.7 MPa alongside a variable end-stop. If your setup requires less force, stepping down to a 160 mm bore yields 14074 N at the same pressure, while the 200 mm bore is necessary for heavy pressing or lifting. The adjustable 75 mm window is ideal for product changeovers, allowing precise end-position tuning without swapping out the entire cylinder or adding external stops.
For ISO 15552 interchangeability, match the 200 mm bore, 550 mm stroke, 75 mm adjustment, PT G3/4 ports, and -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke exceeds 300 mm, an external guide rail is highly recommended to manage side loads. If true load-holding without live air is required, consider the SAIL or BSAI series instead of relying on the rear stopper.
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 SAIJ200X550-75S FAQ
At a 0.7 MPa operating pressure, this 200 mm bore cylinder generates 21991 N of push force and 21991 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw lets you mechanically shorten the 550 mm nominal stroke by up to 75 mm, providing an effective travel range of 475 to 550 mm. This allows for fine-tuning the end position during commissioning without adding external stops.
