About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250U
The AirTAC MBLC63X250U is a double-acting, single-rod mini cylinder engineered for demanding compact automation. It delivers a robust 1558 N push force at 0.5 MPa, utilizing a 63 mm bore and a 250 mm stroke to drive heavier masses. The U designation indicates a rigid flat-end back cover for straightforward inline mounting. Because this specific SKU lacks the -S suffix, it is built without a magnet and cannot accept a CMSG, DMSG, or EMSG position sensor.
This model distinguishes itself from the standard MBL by incorporating a screw-adjustable pneumatic air cushion at both stroke ends. Rather than relying on a fixed rubber bumper that degrades under heavy impacts, the cushion needle smoothly decelerates the piston near the end caps, effectively absorbing kinetic energy to minimize shock and noise. The riveted rolling-packed aluminum barrel keeps the envelope tight and lightweight, while the 20 µm hard-chrome plating on the carbon-steel rod provides essential wear resistance for high-frequency cycling.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250U Is Used
Pallet Transfer Line
Drives a 250 mm stroke pusher arm on a packaging conveyor, moving loaded pallets with 1558 N of force while the adjustable cushion prevents end-cap jarring during rapid cycling.
Injection Mould Ejection
Ejects dense plastic parts from an injection moulding machine, utilizing the tuned pneumatic cushion to decelerate the heavy mould plate smoothly and protect the tooling surface.
Heavy Carton Sorting
Diverts heavy corrugated cartons on a logistics sorter, where the rigid U flat-end mount handles the axial push and the air cushion absorbs the kinetic energy of the fast retracting rod.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250U the Right Cylinder?
Stepping down in force, the 50 mm bore neighbor provides 981 N push at 0.5 MPa, which is suitable if your payload is lighter and you need a slimmer footprint. Stepping up beyond this 63 mm model means moving to a larger ISO 15552 profile cylinder, as MBLC is the largest bore in this mini series. Choose the MBLC over the base MBL when your application runs at high speeds or shifts heavy loads, requiring tuned deceleration rather than a static rubber stop. Remember that the air cushion only decelerates near the ends; it is not a brake, and the rod will drift if air pressure is lost. At 250 mm of stroke, the Ø16 rod is susceptible to bending under lateral loads, so utilizing an external guide rail, a CA or SDB pivot mount, or the MBLD double-rod variant is highly recommended to prevent premature seal failure. Replacement match: 63 mm bore, 250 mm stroke, G1/4 port, PT thread, U back cover, no magnet.
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 MBLC63X250U FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 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 operating pressure.
The MBLC63X250U features a screw-tunable pneumatic needle at both ends. You adjust the needle to trap a pocket of exhaust air, which decelerates the piston smoothly before it hits the end cover. This protects the assembly from impact damage on fast, heavy moves, unlike a fixed rubber bumper. It is strictly a deceleration device, not a load lock.
