About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X400SCA
The AirTAC MBL32X400SCA is a double-acting aluminum mini round cylinder engineered for compact spaces where a larger ISO 15552 profile body cannot fit. At 32mm bore and 400mm stroke, it generates 402 N of push force and 346 N of pull force at 0.5 MPa. The riveted rolling-packed barrel crimps the covers directly to the tube, yielding a light footprint that is not designed to be disassembled like a tie-rod cylinder. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the Ø12 mm carbon steel rod features 20 μm hard-chrome plating for wear and corrosion resistance.
This specific SKU includes a built-in magnet (-S) for use with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensor switches to detect rod position along its 400mm travel. It is fitted with a CA pivot back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion; for faster or heavier moves requiring end-of-stroke deceleration, the MBLC variant is the appropriate choice.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X400SCA Is Used
PCB Conveyor Diversion
Swings via the CA pivot on a pin to deflect printed circuit boards between conveyor lanes during SMT line routing, using the 402 N push force at 0.5 MPa to reliably shift flat panels.
Carton Sorting Arm
Pivots to push lightweight mixed-product cartons on a packaging sorter, where the 400mm stroke provides the extended reach needed to clear adjacent lanes without a profile cylinder footprint.
Sample Tube Transfer
Arcs a gripper between testing stations in a diagnostic analyzer, using the -S magnet and a DMSG solid-state switch to confirm end-of-stroke position before releasing delicate vials.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X400SCA the Right Cylinder?
When sizing this 32mm bore, stepping down to a 25mm bore reduces output to 245 N push at 0.5 MPa, whereas stepping up to a 40mm bore increases force to 628 N. If your application only requires a push or pull action without live air on both sides, consider the MSBL (single-acting push) or MTBL (single-acting pull) alternatives, which are available in 32mm. This SKU features a G1/8 port with a PT thread form, an M10x1.25 rod-end thread, and a CA pivot back cover.
Because the stroke is 400mm, the unsupported Ø12 mm rod has low side-load tolerance and is prone to bending under lateral stress. To manage this, utilize the CA pivot cover with an SDB bracket to self-align the load, install an external guide rail, or switch to the MBLD double-rod type for anti-rotation. Note that the fixed rubber bumper softens impact but does not hold the load; if air pressure is lost, the rod will drift or drop, requiring an external rod lock or pilot-operated check valve for position holding.
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 MBL32X400SCA FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402 N push force and 346 N pull force. At 0.7 MPa, the push force increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa, which is the upper operating pressure limit for this double-acting aluminum body.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion. If your arcing load requires precise end-of-stroke deceleration to prevent shock, you should select the MBLC variant, which features an adjustable air cushion.
