About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X15U
The AirTAC MBLC25X15U is a double-acting aluminum mini cylinder engineered for very short, rapid strokes. It generates 245 N of push force at 0.5 MPa and utilizes a screw-adjustable pneumatic cushion at both ends to decelerate the piston smoothly. This protects the end covers from impact on high-frequency moves. The U designation specifies a rigid flat-end back cover for straightforward mounting.
Because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot support CMSG, DMSG, or EMSG position sensors. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the Ø10 mm carbon-steel rod features a 20 um hard-chrome plating to resist wear. A heterogeneous two-way grease-retaining piston seal ensures consistent lubrication over millions of cycles.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X15U Is Used
PCB Reject Gate
Snaps a small diverter blade 15 mm to eject printed circuit boards off a conveyor, using the adjustable cushion to stop the blade abruptly without bouncing delicate components.
Label Applicator Tamp
Provides a short 15 mm tamp stroke to press adhesive labels onto packaging, relying on the 245 N force and tunable end-cushioning to prevent label slippage on contact.
Connector Insertion
Pushes electronic pin headers into housings on an assembly line, where the 0.5 MPa thrust and rigid U back cover ensure straight, repeatable insertion without end-cover shock.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X15U the Right Cylinder?
This 25 mm bore provides 245 N push and 206 N pull at 0.5 MPa. If your application requires less force, stepping down to the 20 mm bore yields 157 N push, whereas moving up to the 32 mm bore provides 402 N push for heavier loads. Choose this MBLC variant over the base MBL when your cycle speed is high enough that a fixed rubber bumper cannot adequately absorb the impact. Note that a plain cylinder does not hold position if air is lost; the cushion only decelerates near the ends and does not act as a brake. Your direct replacement match is a 25 mm bore, 15 mm stroke, G1/8 port, PT thread, U flat-end back cover, with 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 MBLC25X15U FAQ
At 0.5 MPa, it provides 245 N push and 206 N pull. At 0.7 MPa, push increases to 343 N and pull to 289 N. The maximum theoretical force is 50 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a small amount of exhaust air to decelerate the piston before it hits the end cover. You tune it to match the load and speed, which reduces noise and wear. It is strictly an end-of-stroke damper, not a load lock or brake.
