About the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX130-100
The AirTAC SAIJ50X130-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 130 mm travel back by up to 100 mm. This creates a wide 30 to 130 mm usable stroke window, enabling rapid product changeovers on the line without physically swapping out the actuator. At 0.5 MPa, it delivers 982 N of push force and 825 N of pull force.
Built with a SUS304 stainless steel piston rod (option B), this model is well-suited for environments where corrosion resistance is a priority. It uses PT tapered port threads and features variable air cushions at both ends to manage deceleration. The extruded aluminum barrel includes sensor grooves on both sides for easy switch mounting.
When sizing this actuator, the 50 mm bore provides a solid middle ground between the 40 mm version (628 N push at 0.5 MPa) and the larger 63 mm class (1559 N push at 0.5 MPa). The 100 mm adjustment range is ideal for machinery that processes varying part lengths, acting as an external stop for fine-tuning end positions during commissioning. Remember that the rear adjuster functions strictly as a travel stop, not a lock; a plain SAIJ will not hold a load without live air pressure. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder. Because this is an ISO 15552 profile cylinder, it is dimensionally interchangeable with standard ISO 15552 mounting interfaces, though the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX130-100 Is Used
Variable End Stops
Dial in the exact end position for varying part lengths during machine setup, utilizing the 100 mm adjustment range to trim the 130 mm stroke down to a 30 mm minimum.
Product Changeover
Quickly adapt automated lines to new product sizes by turning the rear adjuster, eliminating the need to physically swap out the entire cylinder.
Corrosive Assembly
Leverage the SUS304 stainless steel rod option for light assembly tasks in washdown or corrosive environments where standard carbon steel rods would fail.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50BX130-100 the Right Cylinder?
Choose the SAIJ50X130-100 when your application requires precise end-position tuning across a 30 to 130 mm travel window. The 50 mm bore generates 982 N of push force at 0.5 MPa, offering a robust output for mid-sized tooling. The 100 mm adjustment range allows operators to dial in the exact stroke needed for different product sizes without adding external stops. To replace this cylinder, match the 50 mm bore, 130 mm nominal stroke, 100 mm adjuster, PT ports, SUS304 rod, and the ISO 15552 mounting footprint. Note that while the SUS304 rod handles side loads well, long unsupported strokes still require an external guide.
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 SAIJ50 Adjustable Cylinder SAIJ50BX130-100 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. It operates at speeds between 30 and 800 mm/s.
The rear adjuster acts as a mechanical stop that can shorten the 130 mm nominal stroke by up to 100 mm, giving you a usable travel window of 30 to 130 mm. It only sets the end position and does not lock the load without live air pressure.
