About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15SCA
The AirTAC MBLC63X15SCA is a compact double-acting aluminum mini cylinder engineered for high-force, short-trroke tasks. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa. A built-in magnet (-S) enables integration with AirTAC CMSG reed and DMSG or EMSG electronic sensor switches for precise end-of-stroke detection. The 15 mm stroke is ideal for high-impact clamping or ejecting operations where space is strictly limited.
Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle allows you to decelerate the heavy 63 mm piston smoothly, minimizing end-cover impact and vibration on fast cycles. The CA pivot back cover swings on a pin to accommodate arcing loads, while the riveted rolling-packed aluminum barrel keeps the body light. The Ø16 mm hard-chrome carbon-steel rod is paired with a heterogeneous two-way grease-retaining piston seal for lasting friction control.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15SCA Is Used
Stamping Press Ejection
Uses the 1558 N push force at 0.5 MPa to knock stamped metal parts out of a die in a fraction of a second, relying on the tuned air cushion to absorb the sudden end-of-stroke impact.
Heavy Pallet Diverter
Swings via the CA pivot bracket to push heavy pallets onto a secondary packaging line, where the 15 mm stroke delivers a rapid, compact diversion without protruding into the walkway.
PCB Test Fixture Clamp
Applies high clamping pressure to secure thick multilayer PCBs for bed-of-nails testing, using the -S magnet and DMSG electronic switch to confirm clamp engagement for the control system.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15SCA the Right Cylinder?
Select this 63 mm bore model when your application requires substantial thrust within a tight footprint. If you need less force, stepping down to the 50 mm bore yields 981 N of push at 0.5 MPa. Stepping up is not possible as 63 mm is the largest standard MBL/MBLC diameter. The PT tapered port thread mates with standard Japanese-style pneumatic fittings, and the CA clevis mount is specifically chosen over the rigid U flat-end cover to handle angular rod movements during arcing motions.
Because the stroke is only 15 mm, side-load bending risks are negligible, but the immense pneumatic force means the cushion needle must be dialed in correctly to prevent shock. Note that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a locking mechanism. If the air supply is lost or the valve centers, the rod will drift, requiring an external pilot-operated check valve for position holding.
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 MBLC63X15SCA FAQ
This 63 mm bore cylinder uses a G1/4 port and a Ø16 mm rod with an M14x1.5 thread. It outputs 1558 N push and 1457 N pull at 0.5 MPa, 2181 N push at 0.7 MPa, and reaches a maximum theoretical force of 318 kgf at 1.0 MPa.
A screw-tunable needle valve at both end covers traps a pocket of exhaust air to decelerate the piston before it hits the end cap. You adjust it to match the load and speed, which reduces impact noise and wear; it functions only as an end-of-stroke damper and does not lock the rod in place.
