About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X40U
The AirTAC MBLC32X40U is a double-acting aluminum mini cylinder engineered for compact actuation, delivering a 402 N push force and 346 N pull force at 0.5 MPa. Its 40 mm stroke is well-suited for short-trjectory clamping or ejection tasks where space is restricted. A defining feature is the screw-adjustable pneumatic cushion at both ends, which decelerates the piston smoothly near stroke limits to reduce impact stress on the rigid U flat-end rear cover.
Unlike fixed rubber bumpers, this air cushion lets you tune end-of-stroke deceleration to match your load and speed, cutting vibration on faster cycles. The body uses a riveted rolling-packed aluminum barrel for a lightweight, space-saving profile rather than a bulky tie-rod housing. Inside, a heterogeneous two-way grease-retaining piston seal works alongside a 20 µm hard-chrome carbon-steel rod to maintain lubrication and resist wear. Note that this specific SKU lacks the -S magnet option, meaning it cannot support CMSG, DMSG, or EMSG position sensing.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X40U Is Used
PCB Router Clamping
Secures printed circuit boards during routing operations, utilizing the 402 N push force and 40 mm stroke to hold panels firmly without crushing components.
Packaging Flap Folding
Drives short-stroke flap tuckers on carton erecting machines, where the tunable air cushion prevents hard stops that would skew lightweight cardboard.
Connector Insertion Press
Provides the 346 N pull force needed to withdraw electronic connectors from test sockets, with end-cushioning protecting delicate pin arrays during high-frequency cycling.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X40U the Right Cylinder?
For lower force requirements, stepping down to the 25 mm bore yields 245 N push at 0.5 MPa, whereas upgrading to the 40 mm bore provides 628 N push for heavier loads. Choose this MBLC variant over the base MBL when your application cycles rapidly or moves enough mass that a fixed bumper would fail to absorb the impact. Since this is a non-magnetized U flat-end model with PT ports, your exact replacement match is bore 32, stroke 40, G1/8 port, M10x1.25 rod thread, PT thread form, U back cover, and no magnet. Keep in mind that the adjustable cushion only decelerates the piston near the ends; it is not a mechanical lock, so the rod will drift if air pressure is lost or the valve centers.
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 MBLC32X40U FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 346 N of pull force. At 0.7 MPa, the push force increases to 563 N. The theoretical maximum output is 82 kgf at 1.0 MPa.
The MBLC32X40U features a screw-tunable needle at both ends that traps exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust the needle to match your specific load and speed, which is critical for high-frequency cycles where a standard fixed rubber bumper would degrade or cause impact damage.
