About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X225SCA
The AirTAC MBLC63X225SCA is a double-acting, aluminum-barrel mini cylinder engineered for heavy-duty motion control within compact spaces. Delivering 1558 N of push force and 1457 N of pull force at 0.5 MPa, this 63 mm bore unit drives substantial loads. The 225 mm stroke provides the travel needed for multi-stage processing or large part ejection. Unlike standard fixed-bumper cylinders, this model features a screw-adjustable pneumatic cushion at both ends, allowing you to precisely tune end-of-stroke deceleration and eliminate damaging impact shocks.
This SKU is highly configured for demanding kinematics. The CA back cover provides a pivot clevis that swings on a pin, accommodating arcing loads without inducing rod-binding stress. The built-in magnet (-S) supports AirTAC CMSG, DMSG, and EMSG sensor switches for precise position detection. Internally, a heterogeneous two-way grease-retaining piston seal works alongside a 20 µm hard-chrome plated carbon-steel rod to ensure low-friction, long-life operation even at high cycling frequencies.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X225SCA Is Used
Injection Mold Ejection
Provides 1558 N of push force at 0.5 MPa to eject dense plastic parts from injection molds, utilizing the adjustable cushion to silently stop the heavy 225 mm stroke without shocking the mold platens.
Pallet Diverting
Leverages the CA pivot clevis to accommodate arcing sweep motions when pushing heavy pallets off a high-speed conveyor line, preventing side-load friction on the 16 mm rod.
Stator Lamination Stacking
Uses the built-in magnet with a DMSG solid-state sensor to confirm press stroke completion during electric motor stator lamination stacking, ensuring precise 225 mm travel limits.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X225SCA the Right Cylinder?
Select this 63 mm bore when your application requires substantial thrust—stepping down to the 50 mm bore drops your push force to 981 N at 0.5 MPa, while the 63 mm provides 1558 N. If you need even more power, note that 63 mm is the largest standard MBL size available. The 225 mm stroke is a custom intermediate length (not a standard catalog increment), chosen to fit specific machinery envelopes. Because this stroke exceeds 200 mm, the 16 mm rod is subject to bending under lateral stress; always use an external guide rail or ensure the CA clevis pivot absorbs the angular momentum to prevent premature seal failure. The adjustable air cushion is critical here: choose this over the base MBL when moving heavy masses at high speeds, as the fixed rubber bumper of the MBL would degrade rapidly under such kinetic energy. Note that the cushion only decelerates the piston near the stroke ends—it is not a mechanical lock, and the rod will drift if air pressure is lost or the valve centers.

- ✓ 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 MBLC63X225SCA FAQ
This 63 mm bore cylinder uses a G1/4 port and a 16 mm rod. It generates 1558 N push and 1457 N pull at 0.5 MPa, 2181 N push at 0.7 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa.
A screw-tunable needle at each end cover traps a pocket of exhaust air to decelerate the piston smoothly before it strikes the end cap. You adjust the needle to match your specific load and speed, which is critical for a 225 mm stroke moving heavy masses, preventing end-cover damage that a fixed rubber bumper cannot absorb.
