Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-50S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 130mm stroke, G1/8 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 Adjustable Cylinder SAIJ32 SAIJ32BX130-50S
The AirTAC SAIJ32X130-50-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 130 mm stroke that can be dialed back by up to 50 mm, yielding an 80-130 mm usable travel window for precise end-position tuning during commissioning. In this B-rod configuration, the piston rod uses SUS304 stainless steel, making it highly suitable for environments where moisture or minor corrosion is a concern.
At 0.5 MPa operating pressure, the 32 mm bore generates 402 N of push force and 345 N of pull force. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE electronic solid-state switches for position feedback. The rear adjuster acts purely as a mechanical stop to set deceleration and travel limits, and it will not hold a load without continuous air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-50S Is Used
Machine Changeover
Dial in the exact 80 to 130 mm travel window during product size transitions without swapping cylinders or reworking external hard stops.
End-Stop Calibration
Use the rear 50 mm adjuster to fine-tune the retract end-position during commissioning, ensuring precise mechanical alignment.
Light-Duty Diverting
Leverage the 402 N push force and SUS304 rod for reliable actuation on packaging lines where minor moisture might be present.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX130-50S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when an application requires variable end-stops or frequent product-size changeovers without swapping out the entire actuator. If your process needs less force, stepping down means adding external stops, but stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa. For load-holding requirements without live air pressure, this standard SAIJ adjuster is not a lock; consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 130 mm stroke, and 50 mm adjustment range. This unit specifies a PT tapered port thread, an SUS304 stainless steel rod (B-type), and a magnet for CMSE/DMSE sensors. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting the FB, CA, CB, and CR foot and clevis brackets. Because the 130 mm stroke is under the 300 mm threshold, side-load stress on the 12 mm rod and M10x1.25 thread is moderate, though external guides remain best practice for heavy radial loads.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32BX130-50S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 130 mm down to as little as 80 mm. It sets the travel end and decelereration point but does not lock or hold the load without live air pressure.
