About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X75CA
The AirTAC MBLC63X75CA is a double-acting aluminum mini cylinder featuring a 63 mm bore and a 75 mm stroke, engineered to deliver a robust 1558 N of push force at 0.5 MPa. Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant incorporates a screw-adjustable pneumatic cushion at both stroke ends. Tuning the cushion needle allows you to smoothly decelerate the heavy 63 mm piston near the end covers, effectively reducing impact shock, vibration, and noise during high-speed or high-frequency cycling.
This specific SKU is configured with a CA pivot back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads. It uses a G1/4 port and a Ø16 mm carbon-steel rod with 20 µm hard-chrome plating to resist wear. Because this model lacks the -S suffix, it is not fitted with a built-in magnet and cannot host a CMSG, DMSG, or EMSG position sensor. The riveted rolling-packed aluminum barrel keeps the unit compact and lightweight for tight machinery spaces, while the heterogeneous two-way grease-retaining piston seal ensures lasting operational lubrication.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X75CA Is Used
Stamping Press Feeders
Drives heavy gripper slides in automated metal stamping lines, utilizing the 1558 N push force at 0.5 MPa to advance thick stock material while the adjustable cushion absorbs the sudden end-of-stroke halt.
Pallet Diverters
Pushes loaded pallets from a main high-speed conveyor belt onto a spur line, where the CA pivot mount absorbs the side-loading forces generated by the shifting weight of the cargo.
PCB Router Clamps
Secures large printed circuit board panels during heavy-duty routing operations, applying 1457 N of pull force at 0.5 MPa to hold the composite substrate rigidly against the machining bed.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X75CA the Right Cylinder?
Stepping down from this 63 mm bore, the 50 mm neighbor provides 981 N of push force at 0.5 MPa, which is sufficient for lighter loads if you need to save space. If you require even more power, note that 63 mm is the largest bore in the MBLC family, offering a maximum theoretical output of 318 kgf at 1.0 MPa. Choose the MBLC over the standard MBL when your application moves heavier masses or cycles fast enough that a fixed rubber bumper would degrade prematurely from the impact.
For replacement or system matching, verify the 63 mm bore, 75 mm stroke, G1/4 port, PT thread form, and the CA pivot back cover. Because this SKU lacks the -S magnet, you cannot mount reed or solid-state switches directly to it; if position detection is required, you must source an -S variant. Since this is a double-acting cylinder, it will not hold its position if air pressure is lost or the valve centers—the rod will drift, as the adjustable cushion only decelerates the piston near the stroke ends rather than locking it in place.
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 MBLC63X75CA FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1558 N of push force and 1457 N of pull force. When operating at 0.7 MPa, the push force increases to 2181 N. The maximum theoretical output is 318 kgf when pressurized at 1.0 MPa.
The MBLC63X75CA features a screw-tunable pneumatic cushion at both ends that traps exhaust air to smoothly decelerate the piston before it strikes the end cover. You adjust the needle valve to match your specific load and speed, which is critical for preventing end-cover damage on heavy 63 mm assemblies. This mechanism only slows the rod near the stroke ends; it does not act as a brake or lock to hold the load in place.
