About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X30U
The AirTAC MBLC50X30U is a double-acting aluminum mini cylinder engineered for compact spaces requiring substantial force, delivering 981 N of push thrust at 0.5 MPa. Its defining feature is the screw-adjustable pneumatic cushion at both stroke ends, which decelerates the piston smoothly to protect the end covers on rapid, heavy moves. This 50 mm bore, 30 mm stroke configuration is purpose-built for short, high-impact cycles where a fixed rubber bumper would degrade prematurely.
Unlike tie-rod rebuildable bodies, this unit utilizes a riveted rolling-packed aluminum barrel for a lightweight, space-saving profile. The Ø16 mm carbon-steel rod features 20 µm hard-chrome plating, paired with a heterogeneous two-way grease-retaining piston seal for lasting friction control. Note that because this specific SKU lacks the -S suffix, it has no internal magnet and cannot support CMSG, DMSG, or EMSG position sensing.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X30U Is Used
PCB Edge Deburring Press
Drives a short 30 mm stroke to clamp and shear burrs from populated circuit boards, utilizing the 981 N push force while the air cushion prevents jarring impacts that could fracture delicate solder joints.
Bottling Line Diverter Gate
Actuates a heavy stainless steel routing flap on a high-speed packaging line, where the tunable end-of-stroke cushioning silently absorbs the kinetic energy of the 50 mm bore without shaking the machine frame.
Injection Mold Parts Ejector
Delivers a rapid, 30 mm punch to free plastic components from a mold cavity, relying on the 20 µm hard-chrome plated Ø16 mm rod to withstand repetitive ejection shock in a compact assembly cell.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X30U the Right Cylinder?
Choose this 50 mm bore when an application demands 981 N of push force at 0.5 MPa within a tight footprint. If you need to step down to reduce mass and flow, the 40 mm bore offers 628 N of push force. If you need to step up for heavier payloads, the 63 mm bore provides 1558 N. Select this MBLC variant over the base MBL when your cycle speeds or moved masses are high enough that fixed rubber bumpers cannot adequately absorb the impact energy.
This SKU features a U flat-end back cover for rigid, straight-line mounting and PT tapered port threads. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a braking mechanism. A plain double-acting cylinder cannot hold position if air pressure is lost or the valve centers—the rod will drift. For position holding without live air, utilize an external rod lock or pilot-operated check valve.
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 MBLC50X30U FAQ
The 50 mm bore generates a push force of 981 N and a pull force of 881 N at 0.5 MPa. At 0.7 MPa, push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa. This model uses a G1/4 port with PT tapered threads and a Ø16 mm rod with an M14x1.5 rod-end thread.
The screw-tunable pneumatic cushion at both ends allows you to regulate the exhaust bleed-off rate, decelerating the piston smoothly before it strikes the end cover. This is critical for high-speed or heavy loads, as it eliminates the sharp impact noise and mechanical wear that a fixed rubber bumper would suffer. It only decelerates near the ends and does not lock the load.
