About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X400SCA
The AirTAC MBLC63X400SCA is a double-acting, 63mm bore aluminum mini cylinder with a 400mm stroke, delivering 1558 N of push force at 0.5 MPa. It features a CA pivot clevis back cover and a built-in magnet for position sensing. Unlike the base MBL series, this variant utilizes a screw-tunable pneumatic cushion at both stroke ends, allowing you to precisely decelerate heavy 318 kgf peak loads and prevent end-cover impact during high-speed cycling.
The riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the 20 µm hard-chrome plated carbon-steel rod resists wear. The heterogeneous two-way grease-retaining piston seal ensures long-term lubrication. The -S code indicates a built-in magnet compatible with CMSG reed and DMSG or EMSG solid-state sensor switches for exact position feedback.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X400SCA Is Used
Automated Press Ejection
Drives a heavy stamping press ejector arm, using the tunable air cushion to smoothly slow the 1558 N push load before the end of the 400mm travel, preventing shock damage to the tooling.
Pallet Diverting Arm
Actuates a sweeping diverter on a packaging line, where the CA pivot clevis absorbs angular side-loads while the cushion softens the rapid retraction of heavy goods.
PCB Stacking Lift
Raises loaded board racks within an electronics assembly cell, relying on the -S magnet and DMSG solid-state switch to confirm the full 400mm extension stroke.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC63X400SCA the Right Cylinder?
At 0.5 MPa, this 63mm bore generates 1558 N push and 1457 N pull. If your application requires less force, the 50mm neighbor offers 981 N push, whereas stepping up is not possible as this is the largest standard MBL size. Choose this MBLC version over the fixed-bumper MBL when moving heavy masses at high speeds where impact shock would damage the cylinder. Note that the air cushion only decelerates the piston near the stroke ends; it is not a locking brake.
With a 400mm stroke on a 16mm rod, side-load tolerance is low. The CA pivot clevis on this SKU allows the body to swing on a pin to accommodate arcing loads, but for rigid linear guidance over this distance, you should add an external guide rail or consider an MBLD double-rod cylinder to prevent rod bending. Replacement match: 63mm bore, 400mm stroke, G1/4 port, PT thread, CA back cover, magnet installed.
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 MBLC63X400SCA FAQ
At 0.5 MPa, the push force is 1558 N and the pull force is 1457 N. At 0.7 MPa, the push force is 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
A screw-tunable needle valve at both ends traps a pocket of exhaust air to decelerate the piston smoothly near stroke ends. You tune the needle to match your load and speed, which reduces impact, noise, and vibration. It is not a load lock or brake.
