About the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X75SCA
The AirTAC MBL32X75SCA 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 75 mm stroke, making it ideal for mid-range actuation. 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 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 to resist wear and corrosion.
This specific SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG (reed), DMSG, and EMSG (electronic) sensor switches to track rod position. It also features a CA pivot back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads. End-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X75SCA Is Used
Flow Wrapper Carton Flap
Provides the exact 402 N push at 0.5 MPa needed to tuck secondary carton flaps on a continuous-motion flow wrapper, with the CA pivot absorbing minor web-alignment shifts.
PCB Router Z-Axis Gating
Gates the Z-axis plunge stroke on a light-duty PCB depaneling router, using the -S magnet and a DMSG solid-state switch to confirm the 75 mm retraction before the spindle descends.
Bearing Race Sorter Diverter
Diverts sintered bearing races down a gravity conveyor, where the compact riveted aluminum body fits between the tight 50 mm machine frame uprights without modification.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL32X75SCA the Right Cylinder?
If your application requires less force, step down to the Ø25 bore model, which provides 245 N push at 0.5 MPa. For heavier lifting, step up to the Ø40 bore, offering 628 N push at 0.5 MPa. Choose the MBLC variant if your cycle speeds demand adjustable air cushioning rather than a fixed rubber bumper, or the MSBL/MTBL single-acting versions if you only need unidirectional push or pull. Because this is a 75 mm stroke, side-load tolerance remains manageable, but the CA pivot cover naturally helps absorb minor angular misalignment.
Note that a plain MBL cylinder does not hold its load when air pressure is lost or the valve is centered; the rod will drift. The rubber bumper only softens end-of-stroke impact and is not a locking brake. If position holding without live pressure is required, install an external rod lock or a pilot-operated check valve. For replacement, match the 32 mm bore, 75 mm stroke, G1/8 port, PT thread, CA pivot back cover, and the -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 MBL32X75SCA FAQ
At 0.5 MPa, the Ø32 mm bore provides 402 N push and 346 N pull. At 0.7 MPa, the push force is 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact. If you need an adjustable air cushion to handle heavier moving masses or faster cycle speeds, select the MBLC variant instead.
