About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X600SU
The AirTAC MBL20X600SU is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It features a 20mm bore and a 600mm stroke, providing 157N of push force and 132N of pull force at 0.5MPa. Because the 600mm stroke exceeds the 500mm standard maximum, this specific SKU is manufactured as a non-standard, made-to-order unit. It includes a U flat-end back cover for rigid mounting and a built-in magnet for position detection.
Unlike tie-rod cylinders, the MBL body uses a riveted rolling-packed aluminum barrel where the covers are crimped to the tube, making it exceptionally light but not designed for field disassembly. The carbon steel piston rod features 20um hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for a long service life. The base end relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable cushion.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X600SU Is Used
PCB Conveyor Routing
Actuates a lightweight routing gate along a 600mm electronics assembly conveyor, using the 157N push force to divert bare PCB panels into testing stations.
Lab Sample Dispenser
Extends a fluid nozzle across a 600mm travel path to deposit reagents into multi-well microplates, relying on the built-in magnet for DMSG sensor confirmation.
Thin Film Unwinder
Tensions and guides a polymer film web over a long stretch in a packaging machine, where the compact 20mm bore prevents excess bulk on the moving carriage.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X600SU the Right Cylinder?
Selecting the MBL20X600SU is appropriate when a 600mm extension is mandatory in a compact footprint, though buyers must note this is a non-standard stroke requiring made-to-order production. If 157N of push at 0.5MPa is excessive for your payload, stepping down is not an option below 20mm in the MBL line; instead, you would step up to the 25mm bore, which yields 245N push at 0.5MPa. For applications needing faster cycle speeds with this extended length, consider the MBLC variant which adds an adjustable air cushion. If you require single-acting spring-return motion, the MSBL (push) or MTBL (pull) variants cover bores 20-40mm.
Because this 8mm rod extends 600mm, it is highly susceptible to bending under side loads; an external guide rail or a pivot bracket is strongly recommended to prevent rod-bearing damage. Additionally, this cylinder cannot hold a load if air pressure is lost or the valve is centered, as the fixed rubber bumper is not a locking mechanism. For exact replacement, match the 20mm bore, 600mm stroke, G1/8 port, PT thread, U flat-end back cover, and confirm the -S magnet requirement for CMSG/DMSG/EMSG sensor switches.

- ✓ 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 MBL20X600SU FAQ
At 0.5MPa, this 20mm bore cylinder outputs 157N push and 132N pull. At 0.7MPa, the push force increases to 220N, with a theoretical maximum of 32kgf at 1.0MPa. The operational speed ranges from 30-800mm/s.
No, the base MBL20X600SU uses a fixed rubber bumper to absorb end-of-stoke impacts, not an adjustable cushion screw. If your payload requires deceleration tuning over the long 600mm travel, you should select the MBLC variant, which features an adjustable air cushion.
