About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X450SCA
The AirTAC MBLC50X450SCA is a double-acting aluminum mini cylinder featuring a 50mm bore and 450mm stroke, delivering 981N of push force at 0.5MPa. It uses a G1/4 port and a Ø16 carbon-steel rod with an M14x1.5 end thread. This configuration includes a built-in magnet for position detection and a CA pivot back cover. Instead of a fixed rubber bumper, it uses a screw-adjustable pneumatic cushion at both ends to smoothly decelerate the piston near stroke limits, absorbing kinetic energy to protect the end covers on high-speed moves.
The riveted rolling-packed aluminum barrel keeps the body compact and lightweight for tight spaces, unlike bulky tie-rod rebuilds. It relies on a heterogeneous two-way grease-retaining piston seal and a 20µm hard-chrome plating on the rod to minimize friction and wear. Because the 450mm stroke creates a long lever arm on the Ø16 rod, side-load tolerance is low; the CA clevis back cover is critical here, allowing the cylinder to swing on a pin to accommodate arcing loads without bending the rod.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X450SCA Is Used
Packaging Flap Diverter
Handles high-speed arcing loads on a packaging conveyor, using the CA pivot and tuned cushion to smoothly swing heavy 450mm-stroke flaps without slamming.
Textile Beam Indexer
Shifts heavy textile beams into processing position, relying on 981N of push force and the cushioned stroke to prevent shock damage at 450mm travel.
Circuit Board Shuttle
Moves populated PCB racks along a 450mm path, using the -S magnet with a DMSG electronic sensor to confirm extended position before the next machine cycle.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X450SCA the Right Cylinder?
If you need slightly less force, step down to the 40mm bore (628N push at 0.5MPa) with a G1/4 port. For heavier pushing, move up to the 63mm bore (1558N push at 0.5MPa). Choose this MBLC over the base MBL when cycling fast or moving a heavy mass, as the needle-tuned air cushion prevents end-cover impact that a fixed bumper cannot absorb. The cushion only decelerates near the ends; it does not lock or hold position if air is lost. For the 450mm stroke, manage side-load with an external guide, the CA pivot, or an MBLD double-rod cylinder. Replacement match: 50mm bore, 450mm stroke, PT port, M14x1.5 rod thread, CA back cover, no mounting bracket, with -S magnet.

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 MBLC50X450SCA FAQ
At 0.5MPa, it provides 981N push and 881N pull. At 0.7MPa, push increases to 1374N. The maximum theoretical force is 200kgf at 1.0MPa.
It has a screw-adjustable air cushion at both ends that decelerates the piston smoothly near stroke limits, which is not a load lock. The -S built-in magnet allows CMSG reed or DMSG/EMSG electronic sensor switches to detect rod position along the 450mm travel.
