About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X100U
The AirTAC MBLC63X100U is a double-acting, 63 mm bore aluminum mini cylinder engineered for compact spaces requiring substantial thrust. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa, making it highly capable for moving heavier masses within tight machinery layouts. The 100 mm stroke provides a balanced range of motion for intermediate workpiece positioning. A defining feature of this MBLC variant is the screw-adjustable pneumatic cushion at both ends, which decelerates the piston smoothly near stroke termination rather than relying on a fixed rubber bumper.
This tunable end-of-stroke control allows you to dial in the needle to match your specific load and velocity, actively reducing end-cover impact, mechanical noise, and vibration during high-frequency or heavy cycles. Constructed with a riveted rolling-packed aluminum barrel for a lightweight yet durable profile, it incorporates a heterogeneous two-way grease-retaining piston seal and a carbon-steel rod plated with 20 µm hard chrome to resist wear. The U designation indicates a rigid flat-end back cover for straightforward inline mounting. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X100U Is Used
Injection Mold Clamping
Provides 1558 N of push at 0.5 MPa to secure plastic injection mold halves, using the adjustable cushion to silently decelerate the 100 mm stroke and prevent press vibration.
Pallet Diverter
Shifts heavy loaded pallets on a packaging conveyor, utilizing the 63 mm bore's 318 kgf maximum force capacity while the tunable end-cushions absorb the sudden mass impact.
CNC Lathe Bar Feeder
Pushes raw bar stock into a CNC lathe collet, where the 100 mm stroke handles intermediate lengths and the cushion needle prevents end-cover shock on rapid retraction.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X100U the Right Cylinder?
Step down to the 50 mm bore if your application requires less force, as it provides 981 N of push at 0.5 MPa; conversely, step up beyond this 63 mm bore only if you need its maximum 318 kgf theoretical output at 1.0 MPa. Choose this MBLC cushioned version over the base AirTAC MBL when your mechanism runs at higher speeds or shifts heavier masses that would overwhelm a fixed rubber bumper. Keep in mind that the adjustable air cushion only decelerates the piston near the ends—it is not a mechanical lock. A plain double-acting cylinder will drift or drop if air supply is lost or the valve centers, so fit an external rod lock or pilot-operated check valve for fail-safe position holding. For a direct replacement, match the 63 mm bore, 100 mm stroke, G1/4 port, PT thread, U flat-end back cover, and non-magnet configuration.

- ✓ 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 MBLC63X100U FAQ
At 0.5 MPa, the 63 mm bore delivers 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 when operating at the 1.0 MPa pressure limit.
The MBLC63X100U features a screw-tunable pneumatic needle at both ends. You adjust these needles to trap a small pocket of exhaust air, decelerating the piston smoothly before it strikes the end cover. This is critical for high-speed or heavy loads to reduce impact noise and vibration, but it functions only as a decelerator, not a load-holding brake.
