This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is SAI32BX95S — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the SAI32BX95S in place of this model. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI32 Standard Air Cylinder SI32BX95S
The AirTAC Airtac SI32 Standard Air Cylinder SI32BX95S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 95mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the drop-in replacement is the SAI32BX95S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI32 Standard Air Cylinder SI32BX95S
The AirTAC SI32BX95S is a discontinued double-acting ISO 15552 profile cylinder with a 32mm bore and 95mm stroke. It delivers 402N push force at 0.5MPa via a G1/8 port. The drop-in replacement is the SAI32BX95S, which shares the exact same interface, stroke, and force. This -B variant features a SUS304 stainless steel piston rod for corrosion resistance, and the -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors.
Upgrading to the SAI32BX95S retains all ISO 15552 mounting dimensions but introduces an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For sizing, a safe working load is roughly 241N (about 60% of the 402N push force), yielding a vertical lift capacity of approximately 20kg with a 2:1 safety margin. The SAI family also adds SAIL, SAIF, and BSAI lock or valve variants absent from the legacy SI line.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI32BX95S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
The SAI32BX95S produces the same force from the same bore — a true drop-in on output. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI32 Standard Air Cylinder SI32BX95S Is Used
Corrosive Sorting
Leverages the SUS304 stainless rod to actuate small diverters in damp washdown environments without rusting.
Small Part Ejection
Uses the 402N push force at 0.5MPa to reliably eject lightweight plastic moulded components from an assembly jig.
Gate Diversion
Cycles a 95mm stroke to pivot a guide rail and redirect small packages on a conveyor belt line.
Replacing the Airtac SI32 Standard Air Cylinder SI32BX95S with the SAI32BX95S
To replace the SI32BX95S, order the SAI32BX95S. Confirm the ISO 15552 mounting fixture, 95mm stroke, G1/8 port, and SUS304 rod (-B). The -S magnet allows for current AirTAC switches (replacing legacy CS1-B/DS1-B). If you need more force, the neighbouring 40mm bore provides 628N push at 0.5MPa. Because this is a standard double-acting cylinder, it will not hold a load without live air; the cushions only decelerate the piston. For load-holding on air loss, use an external pilot check valve or explore the SAIL lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI32BX95S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI32 Standard Air Cylinder SI32BX95S FAQ
Yes, the SI32BX95S is discontinued. The exact drop-in replacement is the AirTAC SAI32BX95S. It is dimensionally interchangeable per ISO 15552, retaining the same 32mm bore, 95mm stroke, G1/8 port, and mounting interface.
The 32mm bore features a G1/8 port. It generates 402N push and 345N pull at 0.5MPa, 563N push at 0.7MPa, 724N push at 0.9MPa, and a theoretical maximum force of 82kgf at 1.0MPa.
