About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X30SU
The AirTAC MBLC50X30SU is a double-acting, 50 mm bore mini cylinder with a 30 mm stroke, engineered for compact automation requiring high force and smooth end-of-stroke control. It delivers a robust 981 N push and 881 N pull at 0.5 MPa, making it ideal for short, high-impact moves. The defining feature of this SKU is the adjustable air cushion at both ends, which allows you to tune the needle to decelerate the piston smoothly, protecting the end covers on fast cycles.
This model includes a built-in magnet (-S) for compatibility with AirTAC CMSG, DMSG, and EMSG sensor switches to detect rod position along its short travel. It features a U flat-end back cover for rigid mounting and a riveted rolling-packed aluminum barrel that keeps the body light for tight spaces. The 20 µm hard-chrome plated carbon-steel rod pairs with a heterogeneous two-way grease-retaining piston seal to ensure lasting friction-free operation.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X30SU Is Used
Stamping Press Ejection
Delivers 981 N of push at 0.5 MPa to knock stamped metal parts out of a die, using the adjustable cushion to absorb the sudden stop at the 30 mm stroke end.
Packaging Lane Diverter
Provides rapid 30 mm actuation to push small cartons between conveyor lanes, relying on the tunable air cushion to prevent jarring impacts that could damage packaging.
Component Sorting Gate
Handles high-speed routing of heavier industrial components into bins, using the 1374 N force at 0.7 MPa and the U flat-end cover for rigid, high-frequency operation.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X30SU the Right Cylinder?
At 0.5 MPa, this 50 mm bore generates 981 N of push force. If your application requires less force, stepping down to the 40 mm bore yields 628 N, while stepping up to the 63 mm bore provides 1558 N for heavier loads. The MBLC cushioned variant is specifically chosen over the fixed rubber bumper of the base MBL when your short 30 mm stroke cycles rapidly and the impact mass requires tunable deceleration rather than a rigid stop.
For replacement matching, verify the 50 mm bore, 30 mm stroke, G1/4 port, M14x1.5 rod thread, PT port thread form, U flat-end back cover, and the built-in magnet. Note that a plain MBLC does not hold position when air is lost; the cushion only decelerates near the ends and is not a brake. For position holding without live air, an external rod lock is required.
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 MBLC50X30SU FAQ
This 50 mm bore cylinder delivers a push force of 981 N and a pull force of 881 N at 0.5 MPa. At 0.7 MPa, the push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa operating pressure.
The MBLC50X30SU features a screw-tunable pneumatic needle at both ends. You adjust the needle to match your load and speed, decelerating the piston smoothly near the stroke ends to cut impact noise and vibration. This is superior to a fixed rubber bumper for high-frequency moves, though it only decelerates and does not lock the load.
