About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-50
The AirTAC SAIJ200X190-50 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering massive thrust up to 21991N at 0.7MPa. It features a robust 40mm SUS304 stainless steel rod and PT tapered ports. The integrated rear stopper allows you to dial back the 190mm nominal stroke by up to 50mm, creating a precise 140-190mm usable travel window for exact end-position tuning during commissioning.
Because the adjuster acts solely as a mechanical stop on the retract end, it decelerates the travel without holding the load pneumatically. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches. For applications needing true load-holding without live air pressure, this cylinder should be paired with a SAIL air-released lock or an external rod lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-50 Is Used
Heavy Press Changeover
Dial in the 140-190mm travel window to accommodate different material thicknesses on a heavy press line without changing out the entire cylinder assembly.
Machine Commissioning
Fine-tune the retract end-position precisely during setup using the 50mm rear stopper screw, avoiding the need for machined external spacers.
Large Fixture Positioning
Leverage the 21991N pull force at 0.7MPa to move heavy jigs, adjusting the stop within the 140-190mm range to align the fixture perfectly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX190-50 the Right Cylinder?
Selecting this 200mm bore size provides immense force, stepping up significantly from a 160mm bore that yields 14074N push at 0.7MPa. The adjustable stroke is ideal for product changeovers on heavy machinery, allowing variable end-stops without physically swapping the cylinder or bolting on external stops. If your process requires the rod to remain locked mid-stroke after a pressure loss, a fixed SAI cylinder paired with a BSAI clamp-lock is required instead of relying on this rear adjuster.
When matching this ISO 15552 cylinder for a direct replacement, verify the 190mm stroke, 50mm adjustment range, PT port threads, and the SUS304 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR styles. For any stroke exceeding 300mm, an external guide is recommended to manage side-load, but at 190mm the 40mm rod handles standard loads well.
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 SAIJ200BX190-50 FAQ
At 0.7MPa operating pressure, this 200mm bore cylinder generates a push force of 21991N and a pull force of 15080N. The maximum push force is 28274N at 0.9MPa.
The rear adjusting screw acts as a mechanical stop that lets you shorten the 190mm nominal stroke by up to 50mm, providing a usable travel window of 140-190mm. It decelerates the end position but does not lock the load without live air pressure.
