About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X175U
The AirTAC MBL32X175U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 402 N push force at 0.5 MPa across its 175 mm stroke, making it well-suited for mid-range part ejection and positioning tasks. The riveted rolling-packed barrel permanently crimps the front and rear covers to the tube, yielding a lightweight body that is not designed to be disassembled or rebuilt like a traditional tie-rod cylinder.
This specific configuration features a rigid U flat-end back cover for straightforward fixed-foot mounting. Internally, a heterogeneous two-way piston seal retains grease for long service life, while the Ø12 mm carbon-steel piston rod features 20 µm hard-chrome plating for high wear and corrosion resistance. Note that because this SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X175U Is Used
PCB Depaneling Router Ejection
Provides 402 N of push force at 0.5 MPa to cleanly eject cut PCB panels from a routing machine fixture, utilizing the 175 mm stroke to clear the spindle area completely.
Bottling Line Diverter Arm
Actuates a lightweight diverter gate on a 32 mm bore conveyor system, using the rigid U flat-end cover for stable mounting while routing glass containers between packaging lanes.
Textile Bobbin Transfer
Transfers yarn bobbins from a winding head to a downstream carousel, where the compact riveted aluminum barrel fits neatly within the tight multi-spindle machine frame.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X175U the Right Cylinder?
Stepping down to the 25 mm bore drops the 0.5 MPa push force to 245 N, whereas stepping up to the 40 mm bore increases it to 628 N. If your cycle requires adjustable end-of-stroke deceleration for heavier moving masses, select the MBLC variant instead of this base model. If the application demands single-acting spring-return movement, consider the MSBL or MTBL series.
With a 175 mm stroke, the unsupported Ø12 mm rod has a relatively low side-load tolerance and can bend if subjected to lateral forces. To manage this, guide the load externally or pivot the cylinder using an SDB bracket and a CA back cover. Remember that this cylinder uses a fixed rubber bumper to soften end-of-stroke impacts; it is not a lock. If pressure is lost or the valve is centered, the rod will drift and drop, so fit an external rod lock or pilot-operated check valve if the load must be held in place.
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 MBL32X175U FAQ
This 32 mm bore cylinder features a G1/8 port and a Ø12 mm rod. It generates 402 N push and 346 N pull force at 0.5 MPa, 563 N push at 0.7 MPa, and a maximum theoretical force of 82 kgf at 1.0 MPa.
No. The base MBL32X175U uses a fixed rubber bumper to absorb end-of-stroke impact; it does not have an adjustable air cushion (you would need the MBLC variant for that). Additionally, because this SKU lacks the -S suffix for a built-in magnet, you cannot mount a CMSG, DMSG, or EMSG sensor switch to detect rod position.
