About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-50S
The AirTAC SAIJ100X200-50-S is a double-acting ISO 15552 profile cylinder featuring a 100mm bore and a 200mm nominal stroke. Equipped with a rear stroke adjuster, it provides a usable travel window of 150-200mm, allowing you to dial back the effective stroke by up to 50mm during commissioning without swapping the cylinder or adding external stops. It delivers robust thrust, generating 3927N of push force and 3681N of pull force at 0.5 MPa.
This variant includes a SUS304 stainless steel rod (material code B) for superior corrosion resistance and features a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port threads match the G1/2 interface. The rear adjuster acts purely as a travel stop to fine-tune end positions, not as a lock, meaning live air is required to hold the load.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-50S Is Used
Variable End-Stop Tuning
Dial in the exact 150-200mm travel distance during machine commissioning to accommodate product size changes without physically replacing the actuator.
Machine Changeover Setup
Rapidly adjust the retract end-position for new product dimensions on a packaging line, using the rear stopper to fine-tune the stroke precisely.
Corrosive Environment Positioning
Leverage the SUS304 stainless steel rod and adjustable 50mm travel window to execute precise movement tasks in environments requiring high corrosion resistance.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX200-50S the Right Cylinder?
Choose this 100mm bore adjustable-stroke cylinder when your machine setup requires precise end-position tuning across a 150-200mm window. If your application needs less force, stepping down to an 80mm bore yields 2513N of push force at 0.5 MPa; if you need more, a 125mm bore offers 6136N. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 25mm rod and M20x1.5 thread handle high side loads, this cylinder is robust, but any stroke of 300mm or more still requires an external guide for unsupported loads. For load-holding without live air pressure, select the SAIL or BSAI series instead, as this adjuster is not a brake. To match this ISO 15552 cylinder, specify the 100mm bore, 200mm stroke, 50mm adjustment, PT ports, and the -S magnet.
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 SAIJ100 Adjustable Cylinder SAIJ100BX200-50S FAQ
At an operating pressure of 0.5 MPa, the SAIJ100X200-50-S generates 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N.
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 is a travel stop, not a lock, so it cannot hold the load without live air pressure.
