About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X80U
The AirTAC MBLC32X80U is a double-acting aluminum mini cylinder engineered for compact actuation, delivering 402 N of push force and 346 N of pull force at 0.5 MPa. An 80 mm stroke makes it well-suited for short-travel positioning on tight-pitch machinery. Unlike the base MBL, this MBLC variant replaces the fixed rubber bumper with a screw-adjustable pneumatic cushion at both ends, allowing you to dial in end-of-stroke deceleration to protect end covers on faster or heavier moves.
This 32 mm bore unit features a Ø12 mm carbon-steel rod with 20 µm hard-chrome plating to resist wear, paired with a heterogeneous two-way grease-retaining piston seal for long-term friction control. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight for space-constrained assembly cells. The U flat-end back cover provides rigid rear mounting, and because this specific SKU lacks a built-in magnet, it cannot accept CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X80U Is Used
PCB Router Z-Axis
Drives the vertical plunge of a compact PCB depaneling router, using the 402 N thrust to cleanly cut fr4 material while the air cushion prevents end-cover shock during rapid 80 mm returns.
Pouch Dispenser
Actuates a mechanical flap that opens film pouches on a packaging line, where the 346 N pull force reliably retracts the mechanism and the cushion smooths out the fast 80 mm travel.
Tray Pusher
Indexes small component trays into a test fixture, utilizing the rigid U flat-end rear mount to hold alignment while the cushioned stroke protects adjacent precision mechanics from vibration.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X80U the Right Cylinder?
If your application requires less force, stepping down to the 25 mm bore yields 245 N of push at 0.5 MPa, whereas moving up to the 40 mm bore provides 628 N for heavier payloads. The 80 mm stroke sits comfortably within the 10-500 mm standard range, meaning no special ordering is required. Choose this MBLC over the fixed-bumper MBL when your cycle rates are high and the fixed impact of a rubber bumper would prematurely wear the end covers or generate excessive noise. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake. A plain double-acting cylinder will drift if air pressure is lost or the valve centers, so fit an external rod lock if you need true position holding without live air. The replacement match for this SKU is: 32 mm bore, 80 mm stroke, G1/8 port, PT thread, U flat-end back cover, no magnet, and no mounting bracket.

- ✓ 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 MBLC Aluminum Alloy Mini Air Cylinder MBLC32X80U FAQ
At 0.5 MPa, the MBLC32X80U delivers 402 N of push force and 346 N of pull force. At 0.7 MPa, it provides 563 N of push and 484 N of pull. The maximum theoretical force is 82 kgf at 1.0 MPa.
The screw-tunable pneumatic cushion at both stroke ends allows you to regulate how quickly the piston decelerates before hitting the end cover. This is critical for high-frequency or heavier 80 mm moves, as it reduces impact shock, lowers noise, and extends cylinder life compared to a fixed rubber bumper. It only decelerates near the ends and does not lock the load.
