About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450CA
The AirTAC MBLC25X450CA is a double-acting aluminum mini cylinder featuring a screw-adjustable air cushion at both ends. It delivers 245 N push and 206 N pull force at 0.5 MPa, utilizing a 10 mm carbon-steel rod with 20 um hard-chrome plating to resist wear. The 450 mm stroke suits extended travel in compact machinery. Because this SKU omits the -S magnet, it cannot accept a CMSG, DMSG, or EMSG position sensor.
The CA pivot clevis back cover allows the body to swing on a pin, accommodating angular or arcing loads without binding. This is critical on a 450 mm stroke, as the 10 mm rod has low side-load tolerance. The riveted rolling-packed aluminum barrel keeps weight down while the heterogeneous two-way grease-retaining piston seal maintains lubrication. The adjustable cushion decelerates the piston smoothly near each end, protecting the end covers on high-frequency moves.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450CA Is Used
PCB Shuttle Mechanism
Moves populated PCB trays through a 450 mm inspection lane, relying on the 245 N push force and tunable cushion to stop smoothly without jarring delicate solder joints.
Pouch Diverter Arm
Swings a lightweight routing flap on a packaging line, where the CA pivot clevis absorbs the angular motion and the air cushion halts the 450 mm travel quietly.
Tray Indexing Pusher
Advances empty product trays into a filling station, using the adjustable needle to fine-tune end-of-stroke deceleration for high-throughput repetitive cycling.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC25X450CA the Right Cylinder?
For sizing, the neighboring 20 mm bore yields 157 N push at 0.5 MPa, while the 32 mm bore provides 402 N. Step up if the 245 N output is insufficient for your load. Choose this MBLC over the base MBL when cycling speeds are high enough that a fixed rubber bumper would cause impact wear. The CA pivot mounting is essential here: at 450 mm, a rigid flat-end U cover would induce severe rod bending under side loads. Always pair this stroke with an external guide rail. Note that the cushion only decelerates; it does not lock the rod if air is lost. Replacement match: bore 25, stroke 450, port G1/8, rod thread M10x1.25, PT thread, CA 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 MBLC25X450CA FAQ
At 0.5 MPa, it provides 245 N push and 206 N pull. At 0.7 MPa, it provides 343 N push and 289 N pull. The maximum theoretical force is 50 kgf at 1.0 MPa.
No. This specific SKU lacks the -S built-in magnet, meaning it cannot host CMSG, DMSG, or EMSG sensor switches. You would need the MBLC25X450CAS variant for reed or electronic position detection.
