About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X350SCA
The AirTAC MBLC20X350SCA is a compact double-acting aluminum mini cylinder featuring a 20mm bore and 350mm stroke. It generates 157 N of push force and 132 N of pull force at 0.5 MPa. Unlike the standard MBL, this variant uses a screw-adjustable pneumatic cushion at both stroke ends. You tune the needle to smoothly decelerate the piston, cutting end-cover impact and vibration on faster moves. The cushion only decelerates near the ends; it is not a load lock.
This SKU includes a CA pivot back cover that swings on a pin to accommodate arcing loads, plus a built-in magnet (-S) for CMSG, DMSG, or EMSG sensor switches. The riveted rolling-packed aluminum barrel keeps the body light, while the Ø8 mm carbon-steel rod features 20 µm hard-chrome plating to resist wear. Because the stroke is 350 mm, the small 8 mm rod has low side-load tolerance, requiring an external guide to prevent rod bending.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X350SCA Is Used
Textile Yarn Guide
Shifts a yarn guide across a 350 mm path. The CA pivot absorbs angular rod stress, while the cushion prevents sudden snapping at the stroke ends.
PCB Sorting Diverter
Pushes lightweight printed circuit boards into testing lanes. The -S magnet triggers a DMSG electronic sensor to confirm full extension.
Label Applicator Arm
Moves a label head over packaging. The 157 N force drives the light tooling, and the adjustable air cushion ensures smooth deceleration.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X350SCA the Right Cylinder?
Step down to the 20 mm bore if you need shorter strokes under 300 mm, or step up to the 25 mm bore (245 N push at 0.5 MPa) if your load exceeds 157 N. Choose this MBLC over the base MBL when your application runs at high speeds or cycles frequently, as the fixed rubber bumper on the MBL cannot absorb the repeated kinetic energy. A plain MBLC does not hold position when air is lost or the valve centers; the rod will drift. Use an external rod lock or pilot-operated check valve for secure positioning without live air.
This replacement matches exactly: 20 mm bore, 350 mm stroke, G1/8 port, PT thread, CA pivot back cover, and an -S magnet. For this 350 mm stroke, the small Ø8 mm rod is highly susceptible to side-loading and bending. Rely on the CA pivot to absorb angular misalignment, or use an external guide rail; alternatively, switch to an MBLD double-rod cylinder for rigid anti-rotation support.

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 MBLC20X350SCA 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. It uses an Ø8 mm carbon-steel rod with an M8x1.25 rod-end thread and a G1/8 port.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston near stroke ends, reducing impact. It is not a brake. The built-in -S magnet works with AirTAC CMSG reed switches, as well as DMSG and EMSG electronic solid-state sensors.
