About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX165-50
The AirTAC SAIJ200X165-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 15708N of push force at 0.5 MPa. With a nominal stroke of 165 mm and a 50 mm adjustment range, it provides a usable travel window of 115 to 165 mm. This allows you to dial in the exact retract position at commissioning without swapping out the cylinder or adding external stops.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and ships without a magnet. It uses a G3/4 PT port and supports an operating speed of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX165-50 Is Used
Heavy Press Tuning
Dial in the exact 115 to 165 mm retract distance during heavy press commissioning to accommodate varying material thicknesses without external stops.
Product Changeover
Quickly adjust the end-stop by up to 50 mm on a packaging line when switching between different product sizes, minimizing machine downtime.
Robotic End Effectors
Provides 15708N of thrust for large robotic grippers, allowing operators to fine-tune the open and close positions to match new fixture geometries.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX165-50 the Right Cylinder?
Choose this 200 mm bore cylinder when an application demands heavy thrust up to 15708N at 0.5 MPa, but requires finer end-position tuning than a fixed-stroke SAI model offers. If your force requirements are lower, stepping down to a 160 mm bore yields 10053N of push force while saving physical space. The rear screw on this SAIJ acts purely as a travel stop to set deceleration, not a lock; it will not hold the load without live air. For position holding without pneumatic pressure, consider an external rod lock, a pilot-operated check valve, or the AirTAC SAIL and BSAI series.
Because the 165 mm stroke is relatively short for this large bore, side-load stress is minimal, but you should still ensure proper alignment using the integrated mounting options. To match this exact ISO 15552 replacement, specify a 200 mm bore, 165 mm stroke, 50 mm adjustment, G3/4 PT ports, SUS304 rod material, and no magnet.

- ✓ 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 SAIJ200BX165-50 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. It can deliver a maximum thrust of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to trim the effective stroke back by up to 50 mm from the nominal 165 mm, creating a usable travel window of 115 to 165 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
