About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X400SU
The AirTAC MBL32X400SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces where a larger profile body will not fit. It delivers a robust 402 N push force at 0.5 MPa across a 400 mm stroke, making it well suited for pushing actuators or moving small jigs over longer linear distances. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube for a lightweight footprint, though it is not designed to be disassembled like a tie-rod cylinder.
This SKU includes a built-in magnet (-S) for non-contact rod position detection using AirTAC CMSG reed or DMSG/EMSG electronic sensor switches. The U flat-end back cover provides a rigid fixed rear mount, while the heterogeneous two-way piston seal retains grease for long service life. The carbon-steel piston rod features a 20 um hard-chrome plating to resist wear and corrosion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X400SU Is Used
PCB Conveyor Diverter
Pushes lightweight PCB trays laterally across a 400 mm conveyor belt using the 402 N push force, fitting neatly within the tight 32 mm bore envelope.
Carton Sorting Gate
Actuates a 400 mm routing flap in a compact packaging line, relying on the built-in magnet to confirm gate open/close status via a DMSG sensor.
Lab Sample Rack Transfer
Indexes sample tubes into a testing carousel over a 400 mm linear path, where the rigid U flat-end rear mount ensures repeatable positioning without rear sway.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X400SU the Right Cylinder?
If you need less force, step down to the 25 mm bore (245 N push @0.5 MPa); if moving heavier payloads, step up to the 40 mm bore (628 N push @0.5 MPa). Because this 400 mm stroke exceeds 300 mm on a Ø12 mm rod, side-load tolerance is low—an external guide, a CA pivot back cover, or the MBLD double-rod anti-rotation type is strongly recommended to prevent rod-bearing bending. The base MBL uses a fixed rubber bumper, not an adjustable cushion; choose the MBLC variant if you need end-of-stroke speed tuning. This model cannot hold a load if air pressure drops; add an external rod lock or pilot-operated check valve for fail-safe positioning. Replacement match: 32 mm bore, 400 mm stroke, G1/8 port, PT thread, U flat-end back cover, with -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 MBL32X400SU FAQ
At 0.5 MPa, the 32 mm bore provides 402 N push and 346 N pull force. At 0.7 MPa, push increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. The double-acting speed range is 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion. If your application requires adjustable cushioning for heavier or faster moving loads, upgrade to the MBLC variant.
