About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X250SCA
The AirTAC MBLC50X250SCA is a compact double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic air cushion at both ends. Delivering a robust 981 N push force at 0.5 MPa, it is built around a riveted rolling-packed aluminum barrel that keeps the body light and spatially efficient for tight machine envelopes. The 250 mm stroke is ideal for mid-range linear actuation, while the integrated magnet (-S) enables precise rod position detection using AirTAC CMSG, DMSG, or EMSG sensor switches.
This variant features a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, making it highly effective for articulated mechanisms. The Ø16 carbon-steel rod features 20 µm hard-chrome plating, paired with a heterogeneous two-way grease-retaining piston seal for prolonged operational life. Tuning the cushion needle decelerates the piston smoothly near each stroke end, effectively absorbing kinetic energy to protect the end covers on high-speed or heavy-mass moves.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X250SCA Is Used
Packaging Flap Folding
Drives a 250 mm articulating arm to fold heavy cardboard carton flaps at high cycle speeds, using the CA pivot to absorb the arcing load and the tuned cushion to prevent end-cover impact.
Pallet Diverting Gate
Actuates a routing gate on a conveyor line, relying on the 981 N push force at 0.5 MPa to deflect loaded pallets while the adjustable air cushion ensures smooth, vibration-free stops.
PCB Tester Shuttle
Moves an electronics test fixture along a 250 mm path, using the integrated magnet with a DMSG electronic sensor to confirm the extended position before initiating high-speed contact testing.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X250SCA the Right Cylinder?
Select this 50 mm bore when an application demands 981 N of push force at 0.5 MPa alongside a 250 mm stroke with tunable end-of-stroke deceleration. If your load requires less force, stepping down to the 40 mm bore provides 628 N push at 0.5 MPa; conversely, moving up to the 63 mm bore yields 1558 N push at 0.5 MPa for heavier payloads. Choose the MBLC over the base MBL when your cycle speeds or moving masses would overwhelm a fixed rubber bumper. Note that the adjustable air cushion only decelerates the piston near the stroke ends and is not a lock; the rod will drift if air is lost or the valve centers.
Because this 250 mm stroke creates a long extension, the Ø16 rod has limited tolerance for side-loading and is susceptible to bending under lateral forces. To manage this, utilize the CA pivot clevis to absorb angular misalignment, install an external guide rail to support the load, or consider the MBLD double-rod type to resist torsion. This configuration includes a G1/4 port, PT thread form, M14x1.5 rod-end thread, and a built-in magnet for CMSG/DMSG/EMSG sensors.

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 MBLC50X250SCA FAQ
This 50 mm bore cylinder uses a G1/4 port and delivers 981 N push and 881 N pull at 0.5 MPa. At 0.7 MPa, it provides 1374 N push and 1233 N pull, with a maximum theoretical force of 200 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust it to match the load and speed, which reduces noise and impact wear; it is a damping feature, not a mechanical lock or brake.
