About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15SU
The AirTAC MBLC63X15SU is a double-acting aluminum mini cylinder engineered for high-force, short-trroke automation. Delivering 1558 N of push force and 1457 N of pull force at just 0.5 MPa, it integrates a built-in magnet (designated by the S code) for non-contact position detection using CMSG reed or DMSG and EMSG solid-state sensor switches. The U code specifies a rigid flat-end back cover, providing a straightforward mounting interface for straightforward linear thrust. The defining feature of this MBLC variant is the screw-adjustable pneumatic cushion at both stroke ends. Instead of relying on a fixed rubber bumper that degrades under repeated high-energy impacts, the cushion needle allows you to fine-tune the end-of-stroke deceleration to match the load and velocity. This smooths the stop, protecting the end covers and reducing mechanical shock on fast, heavy 63 mm bore moves.
This model features a 15 mm stroke, making it highly effective for short clamping or ejection tasks where absolute compactness is required. The riveted rolling-packed aluminum barrel keeps the overall weight down while maintaining structural integrity, which is a distinct advantage over heavier tie-rod constructions in space-constrained machinery. The carbon-steel piston rod is hardened with a 20 µm hard-chrome plating to resist scoring and wear, while the heterogeneous two-way grease-retaining piston seal ensures consistent lubrication for millions of cycles.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15SU Is Used
Injection Mold Ejection
Provides 1558 N of push force at 0.5 MPa to eject dense plastic parts from molds, using the short 15 mm stroke and tunable air cushion to prevent harsh impact on the mold back plate.
Pallet Stopper
Acts as a rigid stop for heavy pallets on a conveyor line, utilizing the flat-end U cover to absorb the initial hit while the cushion needle softens the final deceleration.
Heavy-Duty Staking
Performs short-stroke metal staking or riveting operations where high kinetic energy must be controlled, using the DMSG electronic sensor to trigger the staking cycle at the exact 15 mm endpoint.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X15SU the Right Cylinder?
With a 63 mm bore, this cylinder outputs 1558 N push force at 0.5 MPa, making it the largest standard size in the MBLC family. If your application requires slightly less force, stepping down to the 50 mm bore yields 981 N of push force. Because 63 mm is the largest available bore, there is no larger standard size; for applications needing more than 1558 N, consider using two cylinders in parallel or exploring a different ISO-standard profile. The 15 mm stroke is ideal for very short, high-impact motions. Choose this MBLC cushioned version over the base MBL when the cylinder operates at high speeds or moves a heavy mass, as the fixed bumper on the base MBL cannot absorb the kinetic energy effectively. Note that the adjustable air cushion only decelerates the piston near the end of its travel; it is not a locking mechanism. If the load must be held in place when air pressure is lost or the valve centers, you must add an external rod lock or a pilot-operated check valve. The replacement match for this SKU is: 63 mm bore, 15 mm stroke, PT port thread, U flat-end back cover, no additional mounting bracket, and an S magnet for sensor compatibility.

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 MBLC63X15SU FAQ
The MBLC63X15SU features a 63 mm bore and a 16 mm carbon-steel rod with an M14x1.5 end thread. At 0.5 MPa, it generates 1558 N of push force and 1457 N of pull force. At 0.7 MPa, the push force increases to 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa. It uses a G1/4 port.
The MBLC63X15SU has a screw-tunable pneumatic cushion at both ends. You adjust the needle valve to meter the exhaust air trapped at the end of the stroke, decelerating the piston smoothly before it hits the end cover. This is critical for a 63 mm bore moving heavy loads, as it prevents the impact damage that a fixed rubber bumper would suffer under high kinetic energy.
