About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X150U
The AirTAC MBLC20X150U is a double-acting aluminum mini cylinder featuring a 20 mm bore and 150 mm stroke. It generates 157 N of push force at 0.5 MPa, making it well-suited for lighter duty cycling over a longer travel distance. A defining feature of this MBLC variant is the screw-adjustable pneumatic cushion at both stroke ends, allowing you to precisely tune the end-of-stroke deceleration to protect the end covers on faster moves.
This model features a U flat-end back cover for rigid mounting and uses a PT port thread. It lacks the -S magnet option, meaning it cannot support CMSG, DMSG, or EMSG position sensors. The compact profile is achieved via a riveted rolling-packed aluminum barrel, and the Ø8 mm carbon-steel rod is protected by a 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X150U Is Used
PCB Depaneling Router
Drives a light routing blade over a 150 mm travel to separate circuit boards, using the adjustable air cushion to decelerate the blade smoothly and prevent jarring impacts at the end of the cut.
Connector Insertion Arm
Pushes delicate ribbon connectors into sockets with 157 N of force, relying on the compact 20 mm body to fit inside densely packed electronics assembly fixtures.
Carton Flap Folder
Actuates a small folding mechanism on a packaging line, where the 150 mm stroke closes small cardboard flaps rapidly while the tunable cushion minimizes mechanical noise.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X150U the Right Cylinder?
Select this 20 mm bore when an application demands a 150 mm stroke but only 157 N of push force at 0.5 MPa. If you need more power, stepping up to the 25 mm bore increases push force to 245 N at 0.5 MPa. Conversely, if 150 mm is too much travel, shorter standard strokes like 100 mm are available. Because this is a 150 mm stroke on an 8 mm rod, side-load tolerance is low; using an external guide rail helps prevent rod bending and premature seal wear.
This MBLC version is chosen over the base MBL when cycle speeds or moved masses exceed what a fixed rubber bumper can absorb. The adjustable needle decelerates the piston smoothly but is not a load lock—a plain double-acting cylinder will drift if air pressure is lost. Replacement matches require a 20 mm bore, 150 mm stroke, G1/8 port, PT thread, U flat-end back cover, and 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 MBLC20X150U FAQ
This 20 mm bore cylinder uses a G1/8 port and an M8x1.25 rod thread. 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.
No, this specific SKU lacks the built-in magnet (no -S suffix), so it cannot host CMSG, DMSG, or EMSG sensor switches. You would need the MBLC20X150S variant to enable electronic or reed position detection.
