About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450U
The AirTAC MBLC25X450U is a double-acting aluminum mini cylinder featuring a 25 mm bore and a 450 mm stroke. It generates 245 N of push force and 206 N of pull force at 0.5 MPa. Because this model uses a U flat-end back cover, it provides a rigid, fixed rear mounting interface for straightforward in-line installation.
This unit distinguishes itself from the fixed-bumper base MBL by utilizing a screw-adjustable pneumatic air cushion at both stroke ends. Tuning the cushion needle lets you smoothly decelerate the piston across the lengthy 450 mm travel, absorbing kinetic energy to prevent end-cover impact. The riveted rolling-packed aluminum barrel keeps the body compact, while the Ø10 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450U Is Used
Textile Loom Let-Off
Drives the tensioning arm on a weaving machine, using the 450 mm stroke to feed yarn while the adjustable cushion prevents sudden jerks that would snap fine threads.
Packaging Pusher
Transfers lightweight cardboard cartons between conveyor belts, relying on the 245 N push force and tuned end-deceleration to maintain a high cycle rate without slamming.
Drawer Indexing
Actuates a sliding material drawer in an assembly cell, where the rigid U flat-end mount holds true and the 450 mm travel fully extends the rack for operator access.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450U the Right Cylinder?
Stepping down to the 20 mm bore reduces the output to 157 N push at 0.5 MPa, whereas moving up to the 32 mm bore increases thrust to 402 N. Choose this MBLC variant over the standard MBL when cycling longer distances at higher speeds where a fixed rubber bumper would deteriorate rapidly from the impact. As a drop-in replacement match, verify the 25 mm bore, 450 mm stroke, G1/8 port, PT thread, U flat-end cover, and absence of an S magnet. Because the stroke is 450 mm, the small Ø10 mm rod is highly susceptible to bending under lateral stress; use an external guide rail, a CA or SDB pivot bracket to accommodate arcing loads, or switch to an MBLD double-rod cylinder to prevent binding.
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 MBLC25X450U FAQ
This 25 mm bore cylinder uses a G1/8 port and a Ø10 mm rod with an M10x1.25 thread. It delivers 245 N push and 206 N pull at 0.5 MPa, 343 N push and 289 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
No. The MBLC25X450U SKU does not include the built-in -S magnet, so it cannot trigger AirTAC CMSG reed or DMSG/EMSG electronic switches. You would need to specify an MBLC25X450S variant to enable rod-position detection.
