About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X50-S-U
The AirTAC MBL32X50-S-U is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a 402 N push force at 0.5 MPa alongside a 346 N pull, making it well-suited for mid-range 50 mm strokes. The riveted rolling-packed barrel keeps the body exceptionally light and compact, though it is not designed to be disassembled like a standard tie-rod body.
This specific SKU includes a built-in magnet (-S) for non-contact position detection using CMSG reed or DMSG/EMSG solid-state switches. It features a rigid U flat-end back cover for direct mounting and relies on a fixed rubber bumper to soften end-of-stroke impacts. The carbon-steel piston rod is plated with 20 µm hard chrome to resist wear, while the heterogeneous two-way piston seal retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X50-S-U Is Used
PCB Router Clamping
Secures printed circuit board panels during routing with 402 N of clamping force, fitting neatly into dense electronics assembly machinery.
Carton Flap Folding
Actuates small packaging flaps on compact carton erecting lines where the 50 mm stroke and 346 N pull force provide reliable tucking.
Connector Pick-and-Place
Drives a short 50 mm vertical pick motion in semiconductor test handlers, using the -S magnet to trigger DMSG electronic sensors for precise placement.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X50-S-U the Right Cylinder?
Select this 32 mm bore when a 25 mm cylinder (245 N push @0.5 MPa) lacks thrust or a 40 mm cylinder (628 N push @0.5 MPa) is too bulky. The Ø12 mm rod handles standard loads, but if your application drops when air pressure is lost, note that this cylinder does not hold position—you will need an external rod lock or pilot-operated check valve. The fixed rubber bumper absorbs end-of-stroke shock; for faster cycling with heavier masses, step up to the MBLC variant which offers adjustable air cushioning. Exact replacement requires: 32 mm bore, 50 mm stroke, G1/8 port, PT thread, U flat-end back cover, and the -S magnet.
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 (LB / FA / SDB) and back cover (CA pivot / U flat-end).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBL Aluminum Alloy Mini Cylinder MBL32X50-S-U FAQ
At 0.5 MPa it provides 402 N push and 346 N pull. At 0.7 MPa the push force increases to 563 N. The maximum theoretical force is 82 kgf when operated at the 1.0 MPa pressure limit.
The base MBL uses a fixed rubber bumper that cannot be adjusted; for adjustable air cushioning, you need the MBLC variant. However, this -S model includes a built-in magnet and is fully compatible with AirTAC CMSG, DMSG, and EMSG sensor switches for rod position detection.
