About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X20SU
The AirTAC MBL32X20SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it delivers 402 N of push force and 346 N of pull force across its 20 mm stroke, making it highly effective for short, precise positioning tasks.
This specific SKU includes a built-in magnet (-S) for non-contact position detection using AirTAC CMSG reed or DMSG and EMSG solid-state sensor switches. Unlike tie-rod bodies, the MBL features a riveted rolling-packed aluminum barrel where the covers are crimped to the tube, creating an ultra-light, permanently sealed assembly. The carbon steel piston rod is plated with 20 µm hard chrome to resist wear and corrosion, while a heterogeneous two-way piston seal retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X20SU Is Used
PCB Edge Guiding
Provides 402 N of push force to align circuit boards precisely within an electronics assembly conveyor before component placement.
Small Part Ejection
Uses its 20 mm stroke to rapidly eject machined plastic fittings from a CNC fixture without requiring a large footprint.
Carton Flap Folding
Actuates a short mechanical arm to fold minor flaps on packaging lines, utilizing the DMSG electronic sensor to confirm movement.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X20SU the Right Cylinder?
For lower force requirements, stepping down to the 25 mm bore yields 245 N of push force at 0.5 MPa, whereas stepping up to the 40 mm bore provides 628 N. This MBL32X20SU features a U flat-end back cover for rigid mounting and a default PT tapered port thread. End-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable cushion; choose the MBLC variant if your application requires adjustable air cushions for heavier loads. Note that a plain MBL does not hold its position if air pressure is lost—the rubber bumper only softens impact, so an external rod lock is needed to prevent drifting.
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 MBL32X20SU FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 346 N. At 0.7 MPa, the push force increases to 563 N, with a maximum theoretical force of 82 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL32X20SU uses a fixed rubber bumper to soften end-of-stroke impact and cannot be adjusted. If your application requires adjustable end-of-stroke deceleration, you should select the MBLC variant which features an adjustable air cushion.
