About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X60SCA
The AirTAC MBL20X60SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it provides 157 N of push force and 132 N of pull force over a 60 mm stroke. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, creating an exceptionally light assembly that is not designed to be disassembled or rebuilt like a traditional tie-rod body.
This specific SKU includes a CA pivot clevis back cover, allowing the cylinder to swing freely on a pin to accommodate arcing or angular loads. It also features a built-in magnet (-S) for non-contact position detection using AirTAC CMSG reed or DMSG/EMSG electronic sensor switches. The Ø8 mm carbon-steel piston rod is treated with a 20 µm hard-chrome plating to resist wear and corrosion, while the heterogeneous two-way piston seal retains grease for a long service life.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X60SCA Is Used
PCB Push-off Station
Uses the 157 N push force at 0.5 MPa to gently eject printed circuit boards from an inspection conveyor, relying on the CA pivot to self-align with the edge.
Packaging Flap Folder
Swings on its clevis pin to follow the curved motion of folding small cardboard carton flaps, fitting easily within the narrow side-frame of the sealing machine.
Sample Tube Diverting
Actuates a small pivot arm in a diagnostic analyzer to route blood sample tubes, with the -S magnet triggering a DMSG solid-state switch to confirm the divert position.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X60SCA the Right Cylinder?
Selecting this 20 mm bore unit makes sense when your mechanism requires low-force actuation with angular movement. If you need less force, there is no smaller MBL bore available, but if your application demands more thrust, stepping up to the 25 mm bore increases your 0.5 MPa push force to 245 N. Because this is a base MBL series, end-of-stroke deceleration relies on a fixed rubber bumper rather than an adjustable air cushion; choose the MBLC variant if your moving mass requires tunable shock absorption. Furthermore, a plain double-acting cylinder drifts when air pressure is lost or exhausted, so fit an external pilot-operated check valve if the load must be held safely during an emergency stop. The exact replacement match for this SKU is: 20 mm bore, 60 mm stroke, G1/8 port, PT thread form, CA pivot back cover, no mounting accessory, and a built-in 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 MBL Aluminum Alloy Mini Cylinder MBL20X60SCA FAQ
At 0.5 MPa, this 20 mm bore cylinder generates 157 N of push force and 132 N of pull force. At 0.7 MPa, the push force increases to 220 N, with a theoretical maximum of 32 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL20X60SCA uses a fixed rubber bumper to absorb end-of-stroke impacts, not an adjustable cushion screw. If your application involves faster cycle times or heavier moving masses requiring tunable deceleration, you should upgrade to the AirTAC MBLC adjustable air cushion variant.
