About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-100S
The AirTAC SAIJ40X130-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 130 mm travel by up to 100 mm. This yields a highly versatile 30 to 130 mm usable positioning window, perfect for machines that require frequent product-size changeovers without swapping hardware. It delivers 628 N of push force at 0.5 MPa and 1130 N at 0.9 MPa.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a magnetic piston (-S) for position sensing. The extruded aluminum barrel features sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid ports are PT tapered threads sized at G1/4, and the standard mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-100S Is Used
Product Changeover
Quickly adapt to varying package sizes on a packaging line by dialing the stroke from 30 to 130 mm without changing the cylinder.
Machine Setup
Fine-tune the retract end-position during initial commissioning to achieve precise sensor triggering without adding external stopper hardware.
Adjustable Ejector
Serve as an adjustable parts ejector where the ejection distance varies by product run, relying on the SUS304 rod for durability.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-100S the Right Cylinder?
Select this 40 mm bore when an application demands a wide range of motion tuning within a single form factor; if you need less force, stepping down to a 32 mm bore yields 402 N at 0.5 MPa, while stepping up to a 50 mm bore provides 982 N. The massive 100 mm adjustment window allows precise end-position tuning at commissioning without adding external stops, though the rear screw acts only as a travel stop and does not hold the load without live air. For load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder.
When replacing an ISO 15552 cylinder, match the 40 mm bore, 130 mm nominal stroke, 100 mm adjustment range, G1/4 PT ports, and the -S magnet requirement. Because the stroke exceeds 100 mm, ensure adequate external guidance to prevent excessive side-loading on the SUS304 rod.
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 SAIJ40 Adjustable Cylinder SAIJ40BX130-100S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 100 mm. This creates a usable travel window of 30 to 130 mm, allowing you to set the exact retract end-position during commissioning. The adjuster acts as a mechanical stop and does not lock the load without air pressure.
At 0.5 MPa, it provides 628 N of push force and 528 N of pull force. At 0.9 MPa, the push force increases to 1130 N. The cylinder operates at speeds between 30 and 800 mm/s.
