About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X20CA
The AirTAC MBLC20X20CA is a compact double-acting aluminum mini cylinder engineered for tight spaces, delivering 157 N of push force at 0.5 MPa. Its 20 mm stroke is optimal for short, rapid clamping or ejection sequences. Unlike the base MBL, this variant features a screw-adjustable pneumatic cushion at both ends, allowing you to dial in end-of-stroke deceleration to protect the end covers on fast moves.
This specific SKU includes a CA pivot back cover that swings on a pin to accommodate arcing loads, rather than a rigid flat-end mount. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the Ø8 mm carbon-steel rod with 20 µm hard-chrome plating resists wear. Note that this configuration lacks a built-in magnet, so it cannot support a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X20CA Is Used
PCB Router Z-Axis Stop
Provides a short 20 mm stroke with 157 N of push force to actuate a mechanical end-stop on a PCB depaneling router, using the CA pivot to absorb slight off-center loads.
IC Tube Sealing Press
Closes a small heat-seal jaw on integrated component tubes with 132 N of pull force, relying on the tunable air cushion to prevent jaw bounce at high cycle rates.
Bin Gate Flap Actuation
Opens a lightweight parts-bin diverter flap over a 20 mm travel arc, where the pivot clevis mount handles the angular swing as the flap rotates.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X20CA the Right Cylinder?
For higher force needs, stepping up to the 25 mm bore yields 245 N of push at 0.5 MPa; if lower force is acceptable, this 20 mm bore providing 157 N is the smallest available option. Choose this MBLC over the base MBL when your cycle speeds exceed what a fixed rubber bumper can absorb without excessive impact noise. The adjustable air cushion decelerates the piston smoothly near the stroke ends but is not a load lock—the rod will drift if air is lost. Replacement match: 20 mm bore, 20 mm stroke, G1/8 port, PT thread, CA pivot back cover, no 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 MBLC20X20CA FAQ
This 20 mm bore cylinder uses a G1/8 port and an Ø8 mm rod. It generates 157 N push and 132 N pull at 0.5 MPa, 220 N push at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
A screw needle valve at each end lets you tune the trapped air exhaust to decelerate the piston smoothly near stroke ends, reducing impact and vibration on fast moves. It is a deceleration device, not a brake or load lock.
