About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX550-50
The AirTAC SAIJ200X550-50 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a usable travel window of 500 to 550 mm, allowing you to dial back the nominal stroke by up to 50 mm during commissioning. This bore 200 unit generates a substantial push force of 15708 N at 0.5 MPa, extending to 21991 N at 0.7 MPa, making it suitable for heavy-duty press and lift operations.
This specific configuration uses a SUS304 stainless steel rod for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. The rear adjuster functions purely as a travel stop to fine-tune the end position; it does not lock or hold the load without live air pressure, so an external rod lock or SAIL cylinder is required for static holding.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX550-50 Is Used
Heavy Press Tuning
Dial in the exact 500-550 mm end-stop during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeover
Adjust the retract position on automated assembly lines when switching between product sizes, saving setup time and eliminating external stop hardware.
Long-Stroke Guiding
Execute long linear positioning tasks using the 40 mm SUS304 rod, relying on the rear stop for fine-tuning while external guides handle the lateral loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX550-50 the Right Cylinder?
Selecting this bore 200 adjustable cylinder makes sense when you need precise end-position tuning without adding external stops. If 15708 N at 0.5 MPa is excessive, stepping down to a bore 160 unit provides 10053 N. Because the 550 mm stroke is long and the rod diameter is 40 mm, an external guide is recommended to prevent side-loading damage on the unsupported rod. The G3/4 port and PT tapered threads ensure high flow for the 30-500 mm/s speed range.
For an ISO 15552 replacement match, verify the 200 mm bore, 550 mm stroke, 50 mm adjustment range, G3/4 port, and mounting set. SAIJ uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. No magnet is specified for this SKU, so position sensing requires adding a magnetic piston or external sensors.
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 SAIJ200BX550-50 FAQ
At 0.5 MPa operating pressure, this bore 200 double-acting cylinder provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 550 mm down to 500 mm. It only sets the end position and decelerates the stroke; it does not hold the load without live air pressure.
