About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-10S
The AirTAC SAIJ40X130-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 120 to 130 mm, allowing you to dial in the retract end-position precisely at commissioning without external stops. In the 40 mm bore class, it delivers 628 N of push force and 528 N of pull force at 0.5 MPa, making it well-suited for moderate-load handling tasks.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for position sensing. It operates at speeds of 30-800 mm/s and uses a PT G1/4 port. The extruded aluminum barrel includes sensor grooves on both sides, seamlessly accepting CMSE reed and DMSE electronic switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-10S Is Used
Machine Changeover
Quickly dial in the 120-130 mm travel window during product size changes on a packaging line without physically swapping cylinders or adding external stopper blocks.
Sensor Setup
The integrated magnet works with DMSE electronic and CMSE reed switches in the dual sensor grooves for precise end-of-stroke confirmation during automated assembly.
Corrosion-Resistant Actuation
The SUS304 stainless steel rod handles moderate 628 N thrust forces reliably in humid or washdown manufacturing environments.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX130-10S the Right Cylinder?
Choose this 40 mm bore model when you need 628 N of thrust at 0.5 MPa, stepping up from the 32 mm bore (402 N push) for heavier fixtures, or down from the 50 mm bore (982 N push) to save space. The 10 mm rear adjuster is ideal for product changeovers, letting you fine-tune the 130 mm travel down to 120 mm without swapping the cylinder. Since the adjuster acts only as a travel stop and the air cushions manage deceleration, neither will hold a load without live air; for fail-safe load holding, select an SAIL or BSAI cylinder.
To replace an ISO 15552 cylinder, match the 40 mm bore, 130 mm nominal stroke, 10 mm adjustment range, PT G1/4 port, and the -S magnet. The M12x1.25 rod thread and 30 mm cushion length match standard SAI dimensions. With a 130 mm stroke, side loads are minimal, but always ensure proper guide alignment to prevent binding.

- ✓ 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 SAIJ40BX130-10S FAQ
The rear adjuster screw lets you shorten the nominal 130 mm stroke by up to 10 mm, providing a usable travel window of 120 to 130 mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
At 0.5 MPa, the 40 mm bore generates 628 N of push force and 528 N of pull force. The -S suffix indicates a built-in magnet compatible with AirTAC CMSE reed and DMSE electronic sensors mounted in the barrel grooves.
