About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40SCA
The AirTAC MBLC63X40SCA is a double-acting, 63 mm bore aluminum mini cylinder engineered for demanding actuation. It yields 1558 N of push force and 1457 N of pull force at 0.5 MPa. Unlike the standard MBL, this variant integrates a screw-adjustable pneumatic cushion at both stroke ends. This allows you to fine-tune the end-of-stroke deceleration, preventing end-cover impact when moving heavy loads at high velocities.
The 40 mm stroke is optimal for short, high-force movements. The CA pivot back cover allows the body to swing on a pin, accommodating angular misalignment during arcing motions. A built-in magnet (-S) enables position detection via CMSG, DMSG, or EMSG switches. The riveted rolling-packed aluminum barrel keeps the frame compact, while the 20 µm hard-chrome plating on the carbon-steel rod defends against wear.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40SCA Is Used
Injection Mold Ejection
Drives short 40 mm knockout strokes for heavy plastic injection molds, using the 1558 N push force to break parts loose while the cushion prevents harsh stops.
Pallet Transfer Pivot
Leverages the CA clevis mount to swing a heavy transfer arm across a conveyor line, absorbing the rotational inertia smoothly at stroke ends.
Stator Winding Press
Applies precise 1457 N pull force to seat copper windings in electric motor stators, using the magnet for end-of-stroke confirmation.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X40SCA the Right Cylinder?
This 63 mm bore generates 1558 N push at 0.5 MPa. If your application requires less force, step down to the 50 mm bore, which provides 981 N push. If you need more power, 63 mm is the largest available bore in this mini-cylinder family, offering a maximum theoretical output of 318 kgf at 1.0 MPa. Choose this MBLC over the base MBL when your cycle speeds or moved mass exceed what a fixed rubber bumper can absorb.
The adjustable cushion needle decelerates the piston near the ends but does not lock the rod; if air pressure drops, the load will drift. For position holding without live air, utilize an external pilot-operated check valve. Replacement parts require a 63 mm bore, 40 mm stroke, G1/4 port, PT thread, CA clevis back cover, and an integrated magnet.

- ✓ 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 MBLC63X40SCA FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N push and 1457 N pull. At 0.7 MPa, push increases to 2181 N, with a maximum theoretical output of 318 kgf at 1.0 MPa. It uses a Ø16 mm carbon-steel rod with an M14x1.5 end thread and a G1/4 port.
The CA pivot back cover swings on a pin to accommodate arcing loads, preventing rod binding. The adjustable air cushion at both ends uses a screw needle to tune end-of-stroke deceleration, reducing impact noise and vibration on heavy masses without acting as a mechanical brake.
