About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X75U
The AirTAC MBLC32X75U is a double-acting, 32mm bore aluminum mini cylinder engineered for compact actuation. It delivers 402N of push force and 346N of pull force at 0.5 MPa, making it well-suited for 75mm travel tasks that require precise end-of-stroke control. The defining feature of this MBLC variant is the screw-adjustable pneumatic cushion at both ends, which decelerates the piston smoothly to prevent end-cover impact on faster moves.
Built with a riveted rolling-packed aluminum barrel for a lightweight, space-saving profile, the cylinder houses a heterogeneous two-way grease-retaining piston seal. The carbon-steel rod features 20um hard-chrome plating to resist wear, and the U flat-end back cover provides rigid, straightforward mounting. This specific SKU lacks a built-in magnet, so it cannot be paired with CMSG, DMSG, or EMSG sensor switches for position detection.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X75U Is Used
PCB Router Z-Axis
Drives a lightweight high-speed spindle on a PCB depaneling router, using the 75mm stroke and adjustable cushion to prevent bounce at the stroke end during rapid tool plunges.
Carton Flap Folder
Folds small cardboard flaps on a continuous packaging conveyor, relying on the 402N push force and tunable air cushion to avoid crushing the board at the end of the 75mm travel.
Parts Ejector Gate
Acts as a compact diverter gate on an injection-molded parts conveyor, where the rigid U back cover and 346N pull force reliably retract the gate in tight spaces.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X75U the Right Cylinder?
When sizing this 32mm bore actuator, consider stepping down to the 25mm bore if your load requires less force (it provides 245N push at 0.5 MPa), or stepping up to the 40mm bore for heavier payloads (628N push at 0.5 MPa). Choose the MBLC over the base MBL when your cycle speeds are high enough that a fixed rubber bumper would cause excessive shock or wear. Keep in mind that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake, and a plain double-acting cylinder will not hold position if air pressure is lost. This replacement match features a 32mm bore, 75mm stroke, G1/8 port, PT thread, U flat-end back cover, and no 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 MBLC Aluminum Alloy Mini Air Cylinder MBLC32X75U FAQ
This 32mm bore cylinder uses a G1/8 port and a Ø12mm rod with an M10x1.25 rod-end thread. It generates 402N push and 346N pull at 0.5 MPa, 563N push and 484N pull at 0.7 MPa, with a maximum theoretical force of 82 kgf at 1.0 MPa.
The MBLC32X75U features a screw-tunable needle at both ends that traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust the needle to match your load and speed, which reduces impact shock and noise far better than a fixed rubber bumper. Note that this SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG sensor switches.
