Airtac SAIJ40 Adjustable Cylinder SAIJ40BX155-10
The AirTAC Airtac SAIJ40 Adjustable Cylinder SAIJ40BX155-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 155mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX155-10
The AirTAC SAIJ40X155-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 145-155 mm usable travel window, letting you dial back the nominal 155 mm stroke by up to 10 mm during commissioning. With a 40 mm bore, it delivers 879 N of push force at 0.7 MPa and uses a G1/4 port.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds of 30-800 mm/s. The external adjuster acts purely as a travel stop for end-position tuning, so it will not hold the load without live air pressure. For position holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX155-10 Is Used
Machine Changeover
Dial in the 145-155 mm travel window during product size changes on a packaging line without swapping out the entire cylinder assembly.
End-Position Tuning
Fine-tune the retract stop during initial commissioning to perfect the alignment of clamps and tooling without adding external mechanical stops.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for reliable actuation in food processing or chemical environments where moisture and washdowns are common.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX155-10 the Right Cylinder?
Choose this 40 mm bore adjustable cylinder when an application requires fine end-position tuning on the fly, avoiding the need to swap cylinders or bolt on external stops. If your setup needs less force, stepping down to a 32 mm bore yields 563 N at 0.7 MPa; if more thrust is required, a 50 mm bore provides 1374 N.
This model is dimensionally interchangeable per ISO 15552 and uses a PT tapered port thread. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because it lacks a magnet, it will not work with CMSE or DMSE sensors without a configuration change.
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 SAIJ40BX155-10 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm, creating a 145-155 mm usable travel window. It acts as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
At 0.7 MPa, the SAIJ40X155-10 provides 879 N of push force and 528 N of pull force. It can reach a maximum push force of 1130 N at 0.9 MPa.
