About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X300U
The AirTAC MBLC50X300U is a double-acting aluminum mini cylinder with a 50 mm bore and 300 mm stroke, engineered for compact spaces requiring substantial thrust. It delivers 981 N of push force and 881 N of pull force at 0.5 MPa, scaling to 1374 N push at 0.7 MPa. Unlike the base MBL series, this variant features a screw-adjustable pneumatic air cushion at both stroke endpoints, allowing you to fine-tune the deceleration rate to match heavier loads and prevent end-cover impact during high-frequency operations.
This U back-cover configuration provides a rigid, flat-end rear mounting surface for secure, non-articulating attachment. The riveted rolling-packed aluminum barrel keeps the body lightweight and compact, while the Ø16 carbon-steel rod features 20 µm hard-chrome plating to resist wear and corrosion. A heterogeneous two-way grease-retaining piston seal maintains optimal lubrication over the 30-800 mm/s speed range. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensing without a model change.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X300U Is Used
Pallet Diverters
Pushes 50 kg pallets onto secondary packaging lines using 981 N of force, where the adjustable cushion smoothly arrests the 300 mm travel without jarring the conveyor frame.
CNC Lathe Bar Feeders
Actuates a 300 mm stroke pusher to index bar stock into collets, benefiting from the two-way grease-retaining seal to maintain consistent 30-800 mm/s motion during long cycles.
Warehouse Vertical Lifts
Hoists tote bins between shelving tiers; the rigid U flat-end rear mount provides a stable anchor point while the hard-chrome rod resists scuffing in dusty, high-cycle environments.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X300U the Right Cylinder?
When sizing this 50 mm bore (981 N push @0.5 MPa), step down to the 40 mm bore if your load requires only 628 N, or step up to the 63 mm bore for 1558 N of thrust. The MBLC is the correct choice over the fixed-bumper MBL when your cycle speeds or moving masses exceed what a rubber bumper can safely absorb. Because this is a 300 mm stroke, the 8-16 mm piston rod has a higher susceptibility to side-load bending; for this length, you should utilize an external guide rail, select a CA or SDB pivot mount to absorb angular misalignment, or switch to an MBLD double-rod cylinder to prevent binding. Remember that the adjustable air cushion only decelerates the piston near the stroke ends—it is not a brake or lock, so the rod will drift if air pressure is lost or the valve centers. To match this replacement, use: 50 mm bore, 300 mm stroke, G1/4 port, PT thread, U flat-end back cover, no mounting bracket, and 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 MBLC50X300U FAQ
This 50 mm bore cylinder uses a Ø16 mm rod with an M14x1.5 rod-end thread and a G1/4 port. It provides 981 N push and 881 N pull at 0.5 MPa, 1374 N push and 1233 N pull at 0.7 MPa, with a maximum theoretical force of 200 kgf at 1.0 MPa.
This specific SKU (MBLC50X300U) does not have a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG sensor switches; you would need the MBLC50X300SU version for sensing. The adjustable air cushion at both ends uses a screw needle to tune exhaust flow, decelerating the piston smoothly at the stroke ends to reduce impact, but it does not lock or hold the load.
