About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X10SCA
The AirTAC MBLC20X10SCA is a compact double-acting aluminum mini cylinder engineered for tight spaces. It delivers 157 N push and 132 N pull at 0.5 MPa. The 10 mm stroke is ideal for very short, rapid clamping or ejecting tasks. Unlike the base MBL, this variant features a screw-adjustable air cushion at both ends to smoothly decelerate the piston near stroke limits, absorbing impact on high-frequency moves.
The riveted rolling-packed aluminum barrel keeps the body light and compact without needing tie rods. A heterogeneous two-way grease-retaining piston seal maintains lubrication over long service life. The CA pivot clevis back cover allows the cylinder to swing on a pin, accommodating angular or arcing loads. The built-in magnet (-S) enables compatibility with CMSG reed and DMSG/EMSG electronic sensor switches for precise position detection.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X10SCA Is Used
PCB Router Clamping
Provides 157 N of push force at 0.5 MPa to hold small PCB panels firmly in place on a router fixture, using the 10 mm stroke to engage and retract rapidly without stressing the end covers.
Sensor Bracket Ejection
Ejects small photoelectric sensor brackets from a test nest with a quick 10 mm stroke, where the adjustable air cushion silently stops the rod at the end of each fast cycle.
Pneumatic Gate Diversion
Pivots a small package diverter gate using the CA clevis mount, swinging the arm to route light cardboard cartons on a conveyor line with precise short-travel actuation.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X10SCA the Right Cylinder?
For lower force needs, step down is not available as 20 mm is the smallest bore. For higher force requirements, step up to the 25 mm bore, which provides 245 N push at 0.5 MPa. Choose this MBLC cushioned version over the fixed rubber bumper of the standard MBL when cycling rapidly or moving a heavier mass at high frequency. Note that the adjustable air cushion only decelerates near the ends; it is not a lock or brake. The plain cylinder will not hold position if air is lost or the valve centers. Replacement match: 20 mm bore, 10 mm stroke, G1/8 port, PT thread, CA pivot back cover, with -S magnet.

- ✓ 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 MBLC20X10SCA FAQ
At 0.5 MPa it provides 157 N push and 132 N pull. At 0.7 MPa it provides 220 N push and 185 N pull. The maximum theoretical force is 32 kgf at 1.0 MPa.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly near the stroke limits. You tune the needle to match the load and speed, cutting impact noise and vibration on fast cycles, but it does not lock or hold the rod in place.
