About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-50
The AirTAC SAIJ160X200-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers substantial thrust, providing 14074N push force at 0.7 MPa and 18095N at 0.9 MPa. The integrated adjustment mechanism allows you to dial back the 200mm nominal stroke by up to 50mm, creating a highly flexible 150-200mm usable travel window for precise end-position tuning.
This variant is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of position switches. It operates at speeds of 30-500 mm/s and includes variable air cushions at both ends to manage deceleration, though the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-50 Is Used
Product Changeovers
Dial in the 150-200mm travel window during format conversions on packaging lines without physically swapping cylinders.
Commissioning Tuning
Fine-tune the retract end-position during initial machine setup to perfect seating against heavy 14074N loads.
Variable End Stops
Adjust the stroke dynamically on automated assembly equipment to accommodate varying part sizes on the fly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX200-50 the Right Cylinder?
Select this 160mm bore cylinder when your application requires high pulling force (9425N at 0.5 MPa) alongside variable end-stops for product changeovers. If your setup demands less force, stepping down to a 125mm bore yields 8590N push at 0.7 MPa, while stepping up to a 200mm bore provides 21991N. Choose the SAIJ adjustable-stroke series over a fixed SAI cylinder when you need fine end-position tuning at commissioning without swapping the physical cylinder or adding external stops.
For ISO 15552 interchangeability, match the 160mm bore, 200mm stroke, 50mm adjustment, PT ports, and the SUS304 rod material. Note that SAIJ supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. Because this unit lacks a magnet (-S), it cannot host CMSE or DMSE sensors without modification. If the application requires holding the load safely without live air, use an external pilot-operated check valve or select the SAIL or BSAI series instead.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX200-50 FAQ
At 0.7 MPa operating pressure, this 160mm bore cylinder generates a push force of 14074N and a pull force of 9425N. At 0.9 MPa, the push force increases to 18095N.
The rear adjuster acts as a mechanical stop that lets you shorten the 200mm nominal stroke by up to 50mm, providing a usable travel window of 150-200mm. It sets the end position but does not lock the load without continuous air pressure.
