About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X80SU
The AirTAC MBL32X80SU is a double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a 402 N push force at 0.5 MPa (563 N at 0.7 MPa) across its 80 mm stroke, making it well-suited for mid-range clamping and ejection tasks. The U flat-end back cover provides a rigid fixed rear mounting, ensuring stability when the cylinder is bolted directly to a machine frame.
This SKU includes a built-in magnet (-S) for non-contact position detection, compatible with AirTAC CMSG reed switches and DMSG or EMSG solid-state sensors. Unlike ISO 6432 stainless steel mini cylinders, the MBL features a riveted rolling-packed barrel where the covers are crimped to the tube, creating an exceptionally light and compact profile that is not designed to be disassembled. It relies on a fixed rubber bumper at the end of stroke to soften impact, rather than an adjustable cushion screw.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X80SU Is Used
PCB Router Clamping
Provides 402 N of push force at 0.5 MPa to secure printed circuit boards inside a routing machine, using the 80 mm stroke to position the clamp precisely in a compact equipment bay.
Carton Flap Folding
Actuates a small pneumatic flap folder on a packaging line, where the lightweight riveted aluminum body minimizes moving mass and the U flat-end mounts rigidly to the conveyor frame.
Tester Contact Push
Drives an electrical test probe block into contact with microchips, using the built-in magnet and a DMSG solid-state sensor to confirm the 80 mm extension position for the PLC.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X80SU the Right Cylinder?
For lower force needs, step down to the 25 mm bore which provides 245 N push at 0.5 MPa; for heavier moves, step up to the 40 mm bore offering 628 N. Choose the MBLC variant if your application requires an adjustable air cushion to absorb heavier kinetic energy at the end of the stroke. The base MBL uses a fixed rubber bumper which only softens impact and does not lock the rod. If the load must be held without live air pressure, fit an external pilot-operated check valve or a dedicated rod lock. This specific configuration features a G1/8 port, M10x1.25 rod-end thread, a U flat-end back cover, and a built-in magnet for sensor tracking.
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 MBL32X80SU FAQ
At 0.5 MPa it pushes with 402 N and pulls with 346 N. At 0.7 MPa the push force is 563 N, and the maximum theoretical force is 82 kgf at 1.0 MPa. The cylinder has a 32 mm bore, an 80 mm stroke, a G1/8 port, and an M10x1.25 rod-end thread.
This model has a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion (the MBLC variant offers adjustable air cushioning). Because this SKU includes the -S magnet, you can mount CMSG reed switches or DMSG and EMSG solid-state sensors directly to the body for position detection.
