About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X20SCA
The AirTAC MBLC63X20SCA is a double-acting, 63 mm bore mini cylinder with a 20 mm stroke, engineered for compact setups needing high force and smooth end-of-stroke control. It delivers 1558 N push and 1457 N pull at 0.5 MPa, scaling to a maximum 318 kgf at 1.0 MPa. The riveted rolling-packed aluminum barrel keeps the body light for tight spaces, while the Ø16 carbon-steel rod features 20 µm hard-chrome plating to resist wear. A heterogeneous two-way grease-retaining piston seal maintains lubrication for the 30-800 mm/s speed range.
This SKU includes the CA pivot/clevis back cover, allowing the cylinder to swing on a pin for arcing or angular loads, which is critical for short-stroke, high-thrust pivoting mechanisms. Unlike the base MBL with its fixed rubber bumper, this MBLC model features a screw-adjustable air cushion at both ends. You tune the needle to decelerate the piston smoothly near each stroke end, absorbing kinetic energy to protect the end covers on fast, heavy moves. The built-in magnet (-S) enables position detection via CMSG (reed) or DMSG/EMSG (electronic) sensor switches.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X20SCA Is Used
Press Stamper
Drives a short 20 mm high-force stamping action in aluminum profile notching machines, using the 1558 N thrust to punch thin sheet metal cleanly.
Diverter Flap
Actuates a heavy pivoting diverter arm on a parcel sorting line, where the CA clevis accommodates the angular swing and the cushion absorbs the rapid 20 mm impact.
Pallet Stopper
Locks a heavy pallet in place on a gravity roller conveyor, applying 1457 N pull force to retract the stop gate quickly under high cycle rates.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X20SCA the Right Cylinder?
For applications needing less force, the 50 mm bore neighbor provides 981 N push at 0.5 MPa, while stepping up is not possible as 63 mm is the largest standard MBL size. Choose this MBLC over the fixed-bumper MBL when cycling fast or moving heavy masses that would overwhelm a rubber stop. The PT tapered port, M14x1.5 rod thread, CA clevis back cover, and -S magnet define this exact replacement. Note that the adjustable air cushion only decelerates the piston near the ends; it is not a lock, so the rod will drift if air is lost or the valve centers. Use an external rod lock for position holding without live air.
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 MBLC63X20SCA FAQ
At 0.5 MPa, it provides 1558 N push and 1457 N pull force. At 0.7 MPa, the push force is 2181 N. The theoretical maximum force is 318 kgf at 1.0 MPa operating pressure.
The CA back cover is a clevis that swings on a pin to handle arcing loads, while the screw-adjustable air cushion at both ends traps air to decelerate the piston smoothly near the 20 mm stroke ends, preventing harsh metal-on-metal impact without acting as a load brake.
