About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X30SCA
The AirTAC MBLC20X30SCA is a compact double-acting aluminum mini cylinder featuring a 20mm bore and 30mm stroke. It generates 157N of push force and 132N of pull force at 0.5MPa, making it well-suited for short, rapid positioning tasks. Unlike the base MBL series, this variant utilizes a screw-adjustable pneumatic air cushion at both stroke ends to smoothly decelerate the piston, minimizing impact stress on the end covers during high-frequency cycling.
This SKU includes a CA pivot/clevis back cover that swings on a pin to accommodate arcing angular loads, paired with a built-in magnet (-S) for compatibility with CMSG, DMSG, and EMSG sensor switches. The riveted rolling-packed aluminum barrel keeps the overall envelope small for tight machinery layouts, while the 20µm hard-chrome plated carbon-steel rod resists wear. The heterogeneous two-way grease-retaining piston seal ensures reliable friction performance across the 30-800mm/s speed range.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X30SCA Is Used
Electronic Component Testing
Provides 157N of clamping force at 0.5MPa to hold small PCBs during automated flying-probe testing, using the CA pivot to absorb slight angular misalignments.
Packaging Diverter Arm
Actuates a short 30mm stroke diverter gate on a conveyor routing lightweight cartons, where the adjustable air cushion prevents harsh slamming at high cycle rates.
Pick-and-Place Ejector
Drives a compact vacuum ejector in a tight semiconductor transfer cell, relying on the DMSG solid-state sensor to confirm the 30mm retracted position.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X30SCA the Right Cylinder?
When sizing this 20mm bore actuator, consider stepping down or up based on your load requirements. The next size down is the 12mm bore (not an MBL standard, so you would look outside the family), while the next size up is the 25mm bore, which provides 245N push and 206N pull at 0.5MPa if your 157N output is insufficient. Choose this MBLC model over the fixed rubber bumper of the standard MBL when your application runs at faster speeds or higher cycle frequencies that demand tunable end-of-stroke deceleration. Note that the adjustable cushion only slows the piston near the ends; it does not lock the rod or hold position if air pressure is lost. For exact drop-in replacements, match the 20mm bore, 30mm stroke, G1/8 port, PT thread, CA pivot cover, and -S magnet.
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 MBLC20X30SCA FAQ
At a 0.5MPa operating pressure, this 20mm bore cylinder provides 157N of push force and 132N of pull force. At 0.7MPa, it delivers 220N push and 185N pull. The maximum theoretical force is 32kgf at 1.0MPa.
The MBLC20X30SCA features a screw-tunable needle at both ends that traps a pocket of compressed air to smoothly decelerate the piston before it hits the end cover. You tune the needle to match your specific load and speed, which reduces noise and vibration compared to the fixed rubber bumper found on the base MBL series.
