About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X25U
The AirTAC MBLC25X25U is a double-acting aluminum mini cylinder with a 25mm bore and 25mm stroke. It generates 245 N of push force and 206 N of pull force at 0.5 MPa. The U designation indicates a rigid flat-end back cover for straightforward inline mounting. A defining feature of this variant is the screw-adjustable pneumatic cushion at both ends, which decelerates the piston smoothly near stroke limits to reduce impact wear on faster moves.
This model relies on a riveted rolling-packed aluminum barrel for a compact, lightweight profile that fits tight machine spaces, rather than a bulky rebuildable tie-rod body. It uses a heterogeneous two-way grease-retaining piston seal paired with a 20 µm hard-chrome plated carbon-steel rod. Because this specific SKU lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X25U Is Used
PCB Router Spindle
Positions a small high-speed routing spindle for cutting individual printed circuit boards, using the 25 mm stroke for rapid, cushioned Z-axis plunges that protect the 245 N thrust bearings from sudden stops.
Pick-and-Place Gripper
Actuates a narrow pneumatic gripper on a chip-shooting surface mount machine, where the short 25 mm stroke and tunable end-cushion prevent mechanical shock from vibrating delicate silicon wafers during transfer.
Carton Flap Folder
Folds minor inner flaps on a compact packaging line, leveraging the 206 N pull force and rigid U flat-end rear mount to deliver fast, cushioned tucks without bouncing the cardboard.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X25U the Right Cylinder?
With a 25 mm bore yielding 245 N of push force at 0.5 MPa, stepping down to the 20 mm bore reduces output to 157 N, while moving up to the 32 mm bore increases it to 402 N. Choose this MBLC version over the base MBL when your application runs at higher cycle speeds or moves enough mass that a fixed rubber bumper cannot adequately absorb the end-of-stroke impact. The adjustable needle allows you to tune the deceleration rate to match the load. Keep in mind that the air cushion only decelerates the piston near the ends; it is not a brake. If the air supply is lost or the valve centers, this cylinder will not hold position—you will need an external rod lock or pilot-operated check valve for holding. Replacement match: 25 mm bore, 25 mm stroke, G1/8 port, PT thread, U flat-end back cover, 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 MBLC25X25U FAQ
At 0.5 MPa, the MBLC25X25U provides 245 N of push force and 206 N of pull force. At 0.7 MPa, the push force increases to 343 N. The maximum theoretical force is 50 kgf at 1.0 MPa. It features a G1/8 port with PT tapered threading, a Ø10 mm rod, and an M10x1.25 rod-end thread.
The cushion features a screw-tunable needle at both ends that traps a pocket of exhaust air to decelerate the piston smoothly right before the end cap, reducing impact and noise on faster cycles. Because this specific U-flat-end SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches for position detection.
