About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-100
The AirTAC SAIJ200X105-100 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It features a robust 200 mm bore that generates 15708 N of push force at 0.5 MPa, scaling up to 21991 N at 0.7 MPa. A rear-mounted adjusting screw allows you to dial back the nominal 105 mm stroke by up to 100 mm, creating a highly versatile 5-105 mm usable travel window. This extreme adjustability enables precise calibration during commissioning or rapid product-size changeovers without swapping out the physical cylinder.
Built with a SUS420J2 stainless steel rod (code A) and PT tapered port threads, this extruded aluminum profile cylinder integrates seamlessly into existing setups. The 40 mm rod and M36x2 thread provide exceptional rigidity, handling substantial side loads, while the 50 mm cushioning at both ends ensures smooth deceleration of heavy masses. It supports operating speeds of 30-500 mm/s and uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-100 Is Used
Heavy Press Tuning
Fine-tune the 5-105 mm travel window on large forming presses to accommodate varying material thicknesses without changing out the cylinder.
Product Changeover Stops
Rapidly adjust the rear stopper on heavy-duty conveyor diverters to handle different package sizes on the fly during line changeovers.
Assembly Calibration
Dial in the exact end-of-stroke position during machine commissioning to prevent crushing forces on large components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-100 the Right Cylinder?
Selecting this 200 mm bore adjustable cylinder is ideal when your equipment demands immense thrust—such as 15708 N push at 0.5 MPa—but requires variable end-stops for different product lines. If your application needs less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa. The SAIJ200X105-100 is chosen over a fixed-stroke SAI when mechanical fine-tuning at the rear stopper is necessary to perfect the 5-105 mm travel window during setup. Because the stroke is 105 mm, standard external guiding is recommended to manage side loads. To match this exact ISO 15552 replacement, confirm: 200 mm bore, 105 mm stroke, 100 mm adjustment, PT ports, no magnet, and SUS420J2 rod material.
Remember that the rear adjuster functions strictly as a travel stop, not a locking mechanism. It cannot hold a load without continuous live air pressure. If your machinery requires true load-holding in the event of air loss, you must integrate an external pilot-operated check valve or switch to an AirTAC SAIL or BSAI locking cylinder.
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 SAIJ200AX105-100 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
The rear adjusting screw acts as a mechanical stopper that can shorten the 105 mm nominal stroke by up to 100 mm, giving you a usable travel window of 5 to 105 mm. It only sets the end position and does not lock the load without live air.
