About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X160U
The AirTAC MBLC25X160U is a compact double-acting mini cylinder engineered with a 25 mm bore and 160 mm stroke, delivering 245 N of push force at 0.5 MPa. Because this model uses a U flat-end back cover, it provides a rigid, flush rear mounting surface for straightforward fixed installations. The defining feature over the base MBL is the screw-adjustable pneumatic cushion at both stroke ends. By tuning the needle valves, you control the piston deceleration to match your specific load and velocity, effectively silencing end-cover impact and reducing vibration on faster cycles.
This unit relies on a riveted rolling-packed aluminum barrel to keep the overall footprint tight and lightweight in confined machinery. Inside, a heterogeneous two-way grease-retaining piston seal works alongside a 20 um hard-chrome plated carbon-steel rod (Ø10 mm) to maintain consistent lubrication and resist wear. Please note this specific SKU is supplied without a built-in magnet, meaning it cannot host CMSG, DMSG, or EMSG position sensors for rod detection.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X160U Is Used
PCB Depaneling Router
Drives a linear cutting head across 160 mm to singulate circuit boards, using the adjustable cushion to stop the high-speed traverse smoothly without jarring the fragile substrate.
Carton Flap Folder
Actuates a folding arm on a packaging line, utilizing the 245 N push force to tuck heavy cardboard flaps while the tuned air cushion prevents bounce at stroke end.
Connector Insertion Press
Pushes electronic headers into sockets with a controlled 206 N pull force return, relying on the compact riveted barrel to fit within dense semiconductor handling fixtures.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X160U the Right Cylinder?
Selecting the MBLC25X160U makes sense when your application requires a moderate 245 N push (206 N pull) at 0.5 MPa across a 160 mm travel distance. If your move is slow and light, stepping down to the 20 mm bore yields 157 N of push force while shrinking the envelope. Conversely, if you need to move heavier payloads, stepping up to the 32 mm bore provides 402 N of push force. You should choose this MBLC variant over the standard MBL specifically when cycling speeds are high enough that a fixed rubber bumper would degrade or fail prematurely.
With a 160 mm stroke on a Ø10 mm rod, side-load tolerance is limited; ensure your mechanics guide the load externally to prevent rod bending. For replacement verification, confirm the 25 mm bore, 160 mm stroke, G1/8 port, PT thread form, U flat-end back cover, and the absence of a magnet. Remember that the adjustable air cushion only governs end-of-stroke deceleration; it is not a brake, and the cylinder will not hold position 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 MBLC25X160U FAQ
This 25 mm bore cylinder features a G1/8 port and generates 245 N push and 206 N pull at 0.5 MPa. At 0.7 MPa, output rises to 343 N push and 289 N pull. The maximum theoretical force is 50 kgf at 1.0 MPa.
This specific SKU lacks the -S designation, meaning it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensors. It features a screw-adjustable air cushion at both ends; you tune the needle valves to regulate trapped air exhaust, decelerating the piston smoothly to protect the end covers on fast moves.
