About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X450SCA
The AirTAC MBL20X450SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it generates 157 N of push force and 132 N of pull force across its 450 mm stroke. The riveted rolling-packed barrel keeps the body light and small, though it is not designed to be disassembled and rebuilt like a tie-rod cylinder. The carbon-steel piston rod features a 20 um hard-chrome plating to resist wear and corrosion.
This specific SKU includes a CA pivot back cover, allowing the cylinder body to swing 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 and EMSG electronic sensor switches. End-of-stroke energy is absorbed by a fixed rubber bumper rather than an adjustable air cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X450SCA Is Used
Textile Loom Thread Guide
Uses the CA pivot to swing and maintain tension on moving threads, delivering 157 N of push force over the 450 mm stroke within a compact weaving frame.
Packaging Flap Folder
The built-in magnet triggers a DMSG sensor to confirm carton folding position, while the 132 N pull force retracts the arm in a tight conveyor space.
Sorter Diverter Arm
Pivots on the CA clevis to deflect small parcels down a routing chute, using the 450 mm stroke to clear the passing product path completely.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X450SCA the Right Cylinder?
For lower force needs, step down to the bore 16 variant, or for higher force step up to the bore 25 model which provides 245 N push at 0.5 MPa. If your application requires single-acting spring-return motion, consider the MSBL or MTBL series. To manage end-of-stroke impact on heavier loads, upgrade to the MBLC variant which offers adjustable air cushioning.
With a 450 mm stroke on an Ø8 mm rod, this cylinder has low side-load tolerance and requires an external guide or the CA pivot mount to prevent rod-bearing bending. Note that this cylinder does not hold its load when air pressure is lost; the rod will drift or drop without live pressure. Replacement match: 20 mm bore, 450 mm stroke, G1/8 port, PT thread, CA back cover, 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 MBL20X450SCA FAQ
At 0.5 MPa it provides 157 N push and 132 N pull. At 0.7 MPa push increases to 220 N, with a maximum theoretical force of 32 kgf at 1.0 MPa. The operating speed range is 30-800 mm/s.
No, the base MBL features a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion screw. If you need adjustable air cushioning for heavier loads, select the MBLC variant.
