About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X400SCA
The AirTAC MBLC20X400SCA is a compact double-acting aluminum mini cylinder engineered for a 400 mm stroke. It features a screw-adjustable pneumatic cushion at both ends, allowing you to precisely tune end-of-stroke deceleration. This protects the end covers from impact when moving loads at speed, a significant upgrade over the fixed rubber bumper found on the base MBL series. Delivering 157 N of push force at 0.5 MPa, it is built with a riveted rolling-packed aluminum barrel for a lightweight, space-saving profile.
This specific configuration includes a CA pivot clevis back cover that swings on a pin to accommodate arcing or angular loads, which is essential for a long 400 mm stroke. The built-in magnet (-S) supports AirTAC CMSG, DMSG, and EMSG sensor switches for position detection. Inside, a heterogeneous two-way grease-retaining piston seal works alongside a 20 µm hard-chrome plated carbon-steel rod to ensure reliable service over many cycles.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X400SCA Is Used
Textile Loom Yarn Guide
Drives a yarn guide carriage across a 400 mm weaving width. The adjustable air cushion prevents sudden jerks at the stroke ends, protecting delicate threads from snapping during high-speed loom cycling.
PCB Sorting Diverter
Pivots a sorting arm on a SDB bracket to route printed circuit boards on a conveyor. The 157 N push force easily deflects light PCBs, while the CA clevis absorbs the angular pivot motion smoothly.
Electronic Component Tester
Positions a test probe array over a 400 mm bed of semiconductors. The built-in magnet allows a DMSG solid-state sensor to signal the control system when the probe head is fully extended.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X400SCA the Right Cylinder?
With a 20 mm bore, this cylinder provides 157 N push and 132 N pull at 0.5 MPa. If your application requires less force, you can step down to the 12 mm bore (though note the MBLC series starts at 20 mm, making this the smallest available size). If you need more power, stepping up to the 25 mm bore increases output to 245 N push at 0.5 MPa. Choose this MBLC variant over the standard MBL when your mechanism cycles rapidly or carries enough mass that a fixed bumper cannot adequately absorb the kinetic energy.
At 400 mm of stroke, the Ø8 mm rod has a relatively low tolerance for side loads, making the CA pivot clevis highly beneficial for preventing rod bending. For extreme lateral forces, consider an external guide or the MBLD double-rod type. The replacement match for this SKU is: 20 mm bore, 400 mm stroke, G1/8 port, PT thread, CA pivot back cover, and an -S magnet.

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 MBLC20X400SCA FAQ
At 0.5 MPa, this 20 mm bore cylinder provides 157 N of push force and 132 N of pull force. At 0.7 MPa, the push increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa operating pressure.
It features a screw-adjustable air cushion at both ends that decelerates the piston near stroke extremes to reduce impact and vibration; it is a speed controller, not a load lock or brake. The built-in magnet (-S) allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (electronic) switches along the barrel for non-contact position detection.
