About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-50
The AirTAC SAIJ200X165-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 165 mm nominal travel by up to 50 mm. This yields a usable 115-165 mm end-position window for fine-tuning during commissioning without swapping hardware. It delivers massive thrust, pushing 21991 N at 0.7 MPa and pulling 15080 N, making it suited to heavy-duty positioning tasks.
This variant features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered ports sized at G3/4. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE solid-state switches if a magnet is specified later. Mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-50 Is Used
Heavy Press Setup
Dial in the exact 115-165 mm end-stop during heavy press commissioning to accommodate varying material thicknesses without adding external stopper blocks.
Product Changeover
Quickly adjust the retract position on a conveyor diverter when switching between different pallet sizes on the production line.
Machine Assembly
Fine-tune the clamping travel during large machinery assembly to ensure components mate perfectly without over-traveling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX165-50 the Right Cylinder?
Choose this 200 mm bore when your application demands up to 3204 kgf at 1.0 MPa, stepping down from a 200 to a 160 mm bore drops your 0.5 MPa push force to 10053 N. The adjustable stroke is selected over a fixed SAI cylinder when you need variable end-stops for product changeovers. Because the stroke is 165 mm, an external guide is recommended for heavy loads to manage side-load stress on the 40 mm rod.
The rear adjuster acts as a travel stop to decelerate the load, not a lock. For load-holding without live air, use an external pilot-operated check valve or consider the SAIL or BSAI locking cylinders. This unit is dimensionally interchangeable per ISO 15552 mounting interfaces.
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 SAIJ200AX165-50 FAQ
At 0.7 MPa it provides 21991 N of push force and 15080 N of pull force. At 0.9 MPa the push force increases to 28274 N, with a maximum of 3204 kgf at 1.0 MPa.
The rear adjusting screw lets you shorten the 165 mm nominal stroke by up to 50 mm, creating a usable travel window of 115-165 mm. This stopper decelerates the end of travel but does not lock the load without live air pressure.
