About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X25U
The AirTAC MBLC32X25U is a double-acting aluminum mini cylinder engineered for compact actuation. It generates 402 N of push force and 346 N of pull force at 0.5 MPa. The 25 mm stroke is tailored for high-speed, short-travel clamping or ejection tasks where space is strictly limited. Unlike the base MBL, this variant incorporates a screw-adjustable pneumatic cushion at both ends, allowing you to dial in end-of-stroke deceleration and eliminate hard cover impacts on rapid cycles.
This model features a U flat-end back cover for rigid axial mounting and uses a G1/8 port paired with a Ø12 mm carbon-steel rod. The rod is protected by 20 µm hard-chrome plating, and the internal piston uses a heterogeneous two-way grease-retaining seal for low-friction operation. The riveted rolling-packed aluminum barrel keeps the body light and compact, fitting tight machine envelopes. Note that this specific SKU lacks a built-in magnet, so it cannot host CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X25U Is Used
PCB Drill Bit Changer
Drives a short 25 mm stroke to swap carbide drill bits in CNC PCB routers, using the 402 N thrust to positively seat the toolholder while the cushion prevents shock damage to the spindle bearings.
Connector Insertion Press
Pushes ribbon connectors into electronic PCB sockets, where the 346 N pull force retracts the head cleanly and the dual air cushions stop the 25 mm stroke instantly to avoid crushing fragile plastic housings.
Carton Flap Plow
Deflects minor carton flaps in a continuous packaging line, relying on the compact 32 mm body and rigid U flat-end cover to maintain alignment while the cushion absorbs the repetitive 25 mm impact.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC32X25U the Right Cylinder?
Choose this 32 mm bore when an application demands roughly 400 N of thrust at 0.5 MPa for short, fast moves. If you need less force, step down to the 25 mm bore (245 N push at 0.5 MPa); for heavier loads, step up to the 40 mm bore (628 N push at 0.5 MPa). Select the MBLC over the fixed-bumper MBL when cycling rapidly with a heavier mass, as the tunable needle decelerates the piston smoothly near the ends. Keep in mind the adjustable air cushion only slows the piston near stroke ends; it is not a lock, and the rod will drift if air pressure is lost or exhausted. For a drop-in replacement, match the 32 mm bore, 25 mm stroke, G1/8 port, PT thread, U flat-end 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 MBLC32X25U 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, push increases to 563 N. The maximum theoretical force is 82 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
The cushion is a screw-tunable needle valve at both ends that traps a small pocket of exhaust air to decelerate the piston before it hits the end cover. You adjust the needle to match your load and speed, which reduces impact noise and vibration. It is strictly a deceleration device, not a load lock or brake.
