About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X25SCA
The AirTAC MBLC50X25SCA is a compact double-acting aluminum mini cylinder engineered for short, high-force linear motion. It delivers a robust 981 N push and 881 N pull at 0.5 MPa, making this 50 mm bore, 25 mm stroke unit ideal for tight-space actuation where power density matters. The defining feature over the base MBL is its screw-adjustable pneumatic cushion at both stroke ends, which decelerates the piston smoothly to protect the end covers on fast, heavy moves.
This specific SKU includes a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, and a built-in magnet (-S) for position detection. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the heterogeneous two-way grease-retaining piston seal paired with a 20 µm hard-chrome carbon-steel rod ensures lasting friction control. It operates at speeds of 30-800 mm/s and uses a G1/4 port with an M14x1.5 rod-end thread.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X25SCA Is Used
Short-Stroke Stamping
Ideal for driving a high-force 981 N stamping or embossing head in a confined electronics packaging line, where the 25 mm travel and tunable cushion absorb the end-of-stroke impact.
Pallet Diverter
Perfect for actuating a heavy diverter arm on a packaging conveyor; the CA pivot bracket accommodates the side-arcing motion while the cushion prevents shock damage during rapid 50 mm bore actuation.
PCB Test Press
Suited for applying 881 N of clamping pull force on a PCB test fixture, using the -S magnet with a DMSG electronic sensor to confirm the exact 25 mm closed position for high-speed testing.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X25SCA the Right Cylinder?
Select this 50 mm bore when an application demands high thrust in a compact footprint. If you need less force, stepping down to the 40 mm bore yields 628 N push at 0.5 MPa; if you require more power, the 63 mm bore provides 1558 N push. Choose this MBLC variant over the fixed-bumper MBL when cycling speeds are high or the moved mass is heavy enough that a rigid impact would damage the machine. The CA clevis mount is optimal for mechanisms requiring articulation.
For position feedback, the integrated magnet supports AirTAC CMSG (reed), DMSG, and EMSG (electronic/solid-state) sensor switches. Note that the adjustable air cushion only decelerates the piston near the end of travel; it is not a brake. If the application requires holding position without live air pressure, an external rod lock or pilot-operated check valve must be fitted. This SKU uses PT port threads.
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 MBLC50X25SCA FAQ
This 50 mm bore cylinder provides 981 N push and 881 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum theoretical force of 200 kgf at 1.0 MPa. It uses a G1/4 port and features a Ø16 mm rod with an M14x1.5 rod-end thread.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly before it hits the end cover. You tune it to match your load and speed, which cuts noise and vibration; however, it is strictly an end-of-stroke damper, not a load lock or brake.
