About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250CA
The AirTAC MBLC63X250CA is a double-acting aluminum mini cylinder engineered with a screw-adjustable pneumatic cushion at both ends. Generating 1558 N of push force at 0.5 MPa, it is built around a 63 mm bore, a 250 mm stroke, and a Ø16 hard-chrome carbon-steel rod. The CA pivot back cover allows the body to swing on a pin, accommodating angular motion without binding. A riveted rolling-packed aluminum barrel keeps the frame compact for tight machinery, while a heterogeneous two-way grease-retaining piston seal maintains lubrication across high cycle counts.
This specific configuration uses a standard PT tapered port and lacks a built-in magnet, meaning it cannot host a CMSG, DMSG, or EMSG position sensor. The adjustable air cushion is the defining feature here: rather than slamming into a fixed rubber bumper, the needle valve lets you fine-tune end-of-stroke deceleration to protect the end covers on heavier or faster moves. Note that the cushion only slows the piston near the ends; it is not a load lock or brake.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250CA Is Used
CNC Lathe Bar Feeder
Pushes heavy raw bar stock into collets with 1558 N force, using the adjustable cushion to prevent jerky stops during rapid loading.
Pallet Transfer Pivot
Uses the CA clevis mount to swing a loaded pallet diverter arm smoothly, absorbing the 250 mm stroke mass without end-cover shock.
Heavy Cart Ejection
Ejects filled packaging carts from a conveyor line, relying on the 2181 N thrust at 0.7 MPa and tuned deceleration for quiet operation.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X250CA the Right Cylinder?
With a 63 mm bore yielding 1558 N push and 1457 N pull at 0.5 MPa, stepping down to the 50 mm bore drops the output to 981 N push, whereas stepping up is not an option as 63 mm is the largest standard MBL/MBLC size. Choose this MBLC variant over the fixed-bumper MBL when your application cycles rapidly or moves a substantial mass that would damage a rigid stop. Since this 250 mm stroke is substantial, the small 16 mm rod has limited side-load tolerance; use an external guide rail, leverage the CA pivot mount, or switch to an MBLD double-rod cylinder to prevent rod bending. A plain double-acting cylinder drifts when air is lost, so add an external rod lock for fail-safe holding. Replacement match: 63 mm bore, 250 mm stroke, G1/4 port, PT thread, CA pivot 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 MBLC63X250CA FAQ
This cylinder uses a G1/4 port and delivers 1558 N push and 1457 N pull at 0.5 MPa. At 0.7 MPa, it yields 2181 N push and 2040 N pull, with a theoretical maximum of 318 kgf at 1.0 MPa.
No, this specific SKU lacks the built-in magnet option, so it cannot accept CMSG, DMSG, or EMSG sensor switches. You would need an MBLC63X250S variant for electronic or reed switch position detection.
