About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X450U
The AirTAC MBLC50X450U is a double-acting aluminum mini cylinder engineered to deliver 981 N of push force at 0.5 MPa across a 450 mm stroke. Because this SKU lacks the -S suffix, it is built without a magnet and cannot host a CMSG, DMSG or EMSG position sensor. The U designation signifies a flat-end back cover, providing a rigid rear mounting interface for straightforward in-line bolting. A G1/4 port and a Ø16 hard-chrome carbon-steel rod handle the high air volume and thrust required for moving substantial loads.
Instead of a fixed rubber bumper, this model uses a screw-adjustable pneumatic cushion at both stroke ends. You tune the needle to smoothly decelerate the piston before impact, which is critical for a long 450 mm travel where peak velocities generate significant kinetic energy. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the heterogeneous two-way grease-retaining piston seal ensures consistent friction and lubrication over high-frequency cycles.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X450U Is Used
Pallet Transfer Pusher
Uses the 981 N push force to index heavy loaded pallets off a main conveyor line, relying on the adjustable cushion to stop the 450 mm stroke smoothly without jarring the load.
CNC Lathe Loader
Extends raw bar stock into a collet chuck, where the tunable end-of-stroke deceleration prevents the piston from slamming the heavy steel material against the spindle face.
Vertical Lift Gate
Raises a heavy access guard on a packaging machine, using the 881 N pull force to retract the gate while the dual air cushions absorb the descending gravitational load.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X450U the Right Cylinder?
Selecting the MBLC50X450U makes sense when your mechanism requires a 450 mm travel with heavy mass, as the 50 mm bore yields 981 N push and 881 N pull at 0.5 MPa. If your load is lighter, stepping down to the 40 mm bore drops the output to 628 N push but saves space; conversely, moving up to the 63 mm bore increases thrust to 1558 N for highly resistive loads. Choose this MBLC variant over the base MBL specifically because the adjustable air cushion protects the end covers from high-impact damage on fast 450 mm extensions, whereas the base MBL relies solely on a fixed rubber bumper.
With a 450 mm stroke, the Ø16 rod is highly susceptible to bending under lateral stress. To manage side loads, use an external rail guide, select a CA or SDB pivot bracket to allow articulation, or switch to an MBLD double-rod cylinder. For exact replacement matching, confirm the 50 mm bore, 450 mm stroke, G1/4 port, PT thread, U flat-end back cover, and the absence of a magnet. Note that the air cushion only decelerates the piston near the ends; it is not a brake, and the rod will drift if air pressure is lost or the valve centers.
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 MBLC50X450U FAQ
This 50 mm bore cylinder features a G1/4 port and a Ø16 rod. It generates 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 output of 200 kgf at 1.0 MPa.
No. Because the model code lacks the -S suffix, this specific SKU is manufactured without a built-in magnet and cannot support CMSG, DMSG or EMSG sensor switches for rod position detection.
