About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X350SU
The AirTAC MBLC63X350SU is a double-acting aluminum mini cylinder engineered for heavy-duty compact actuation, generating 1558 N of push force and 1457 N of pull force at 0.5 MPa. Driven by air filtered to 40 µm, it operates smoothly across a 30-800 mm/s speed range. The 350 mm stroke suits extended traverses in automated machinery, while the built-in magnet (-S) enables position detection. A U flat-end back cover provides rigid, straight-line mounting.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle decelerates the piston near the stroke limits, absorbing kinetic energy from fast or heavy 318 kgf peak loads to protect the end covers. The riveted rolling-packed aluminum barrel keeps the body compact, while the Ø16 mm carbon-steel rod is protected by a 20 µm hard-chrome plating and sealed by a heterogeneous two-way grease-retaining piston seal.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X350SU Is Used
Pallet Transfer Reject Gate
Uses the 350 mm stroke and 1558 N push to divert heavy timber pallets off a high-speed conveyor, with the adjustable air cushion absorbing the mass impact at the stroke end.
CNC Lathe Bar Feed Pusher
Feeds heavy steel bar stock into a lathe spindle, relying on the -S magnet and DMSG electronic sensor to confirm the full 350 mm extend position before the chuck closes.
Automated Warehousing Extractor
Extracts loaded steel totes from high-density storage racks, using the U flat-end cover for rigid alignment while the cushion slows the 318 kgf peak load smoothly.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X350SU the Right Cylinder?
At 0.5 MPa, this 63 mm bore yields 1558 N push and 1457 N pull. If your payload is lighter, stepping down to the 50 mm bore reduces the push force to 981 N, saving air volume. If you need more power, there is no larger standard MBL/MBLC bore, so you would transition to an ISO 15552 profile cylinder. Choose this MBLC over the fixed-bumper MBL when cycling high masses at high frequency, as the tunable cushion prevents end-cover impact damage. Note that the cushion only decelerates near the ends; it is not a brake, and the rod will drift if air is lost or the valve centers, so fit an external rod lock for fail-safe holding.
For exact replacement, match the 63 mm bore, 350 mm stroke, G1/4 port, M14x1.5 rod thread, PT thread form, U flat-end back cover, and the -S magnet. Because the 350 mm stroke is substantial for a Ø16 mm rod, side-load tolerance is low. Prevent rod bending by guiding the load externally, using a CA or SDB pivot bracket for arcing motion, or switching to an MBLD double-rod 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 MBLC63X350SU FAQ
At 0.5 MPa, the push force is 1558 N and the pull force is 1457 N. At 0.7 MPa, the push force reaches 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa, which is the upper operating pressure limit for this cylinder.
A screw-tunable needle valve at both ends traps a pocket of exhaust air to decelerate the piston smoothly before it hits the end cover. You dial the needle to match the load and speed, which cuts impact noise and vibration on heavy 350 mm moves. It only acts near the stroke ends and does not lock or hold the load in place.
