About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X75U
The AirTAC MBLC25X75U is a double-acting aluminum mini cylinder featuring a 25mm bore and 75mm stroke. It generates 245N of push force and 206N of pull force at 0.5MPa, making it well-suited for compact mid-range positioning tasks. The U suffix denotes a rigid flat-end back cover for straightforward inline mounting.
This variant distinguishes itself from the base MBL by utilizing a screw-adjustable air cushion at both stroke ends rather than a fixed rubber bumper. By tuning the cushion needle, you control end-of-stroke deceleration to absorb impact on faster moves. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the heterogeneous two-way grease-retaining piston seal works alongside the 20μm hard-chrome plated carbon-steel rod to maintain lubrication and extend seal life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X75U Is Used
PCB Shuttle Routing
Transfers populated circuit boards between inspection stations with 245N push force, using the adjustable air cushion to halt the 75mm stroke gently without jarring delicate solder joints.
Pick-and-Place Gripper Actuation
Drives a small pneumatic gripper arm in a tight electronics assembly cell, relying on the compact 25mm body and tunable end-covers to prevent mechanical shock during rapid part placement.
Carton Flap Folding
Pushes lightweight packaging flaps into position on a continuous cartoner, utilizing the 206N pull force and rigid U back cover to maintain straight-line stability in a confined machine section.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X75U the Right Cylinder?
Stepping down to the 20mm bore reduces output to 157N push at 0.5MPa, whereas moving up to the 32mm bore increases it to 402N, giving you clear sizing boundaries for this 245N class. Choose this MBLC model over the standard MBL when your cycle speeds exceed what a fixed rubber bumper can safely absorb. Keep in mind that a plain double-acting cylinder cannot hold position if air pressure drops or the valve centers; the rod will drift, so an external pilot-operated check or rod lock is necessary for fail-safe holding. As specified, this PT-threaded U-cover SKU lacks the built-in magnet, meaning it cannot accept a CMSG, DMSG, or EMSG position sensor.
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 MBLC25X75U FAQ
At 0.5MPa, this 25mm bore cylinder provides 245N of push force and 206N of pull force. At 0.7MPa, push increases to 343N. The maximum theoretical force is 50kgf at 1.0MPa.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly near the stroke limits, reducing impact noise. It is strictly a speed-damping feature, not a brake or lock; the cylinder cannot hold a load in place without continuous air pressure.
