About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X150SCA
The AirTAC MBL20X150SCA is a double-acting aluminum mini round cylinder engineered for compact spaces where lightweight actuation is essential. At its core, a heterogeneous two-way piston seal actively retains grease to sustain smooth operation over long duty cycles, while the Ø8 mm carbon-steel piston rod features 20 μm hard-chrome plating to resist wear and surface corrosion. With a 150 mm stroke, it provides 157 N of push force and 132 N of pull force at 0.5 MPa, making it well-suited for moving small jigs or ejecting light parts over a longer travel distance.
This specific SKU features a built-in magnet (-S) for non-contact position sensing using AirTAC CMSG reed or DMSG/EMSG electronic switches. The CA pivot back cover allows the cylinder body to swing freely on a clevis pin, accommodating arcing or angular loads that would impose severe side-loading stress on a rigidly fixed alternative. Deceleration at end-of-stroke relies on a fixed rubber bumper, which effectively absorbs impact without the adjustability of the MBLC air-cushion variant.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X150SCA Is Used
Textile Yarn Guide
Swings on a clevis pin to perfectly track yarn carriers across a 150 mm path, using the 157 N push force to maintain tension without snapping delicate fibers.
PCB Shuttle Divert
Shifts populated circuit boards between inspection lanes, relying on the -S magnet and DMSG electronic switch to confirm the 150 mm extend position for robotic pickup.
Small Parts Ejector
Kicks lightweight plastic caps off a molding fixture at 30-800 mm/s, utilizing the CA pivot to self-align and absorb the angular shock of the ejection arc.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X150SCA the Right Cylinder?
For lower force needs, stepping down is not an option as 20 mm is the smallest MBL bore. Stepping up to the 32 mm bore increases thrust significantly to 402 N push at 0.5 MPa, offering a robust upgrade if your payload exceeds 157 N. If your process requires single-acting spring-return actuation, the MSBL push or MTBL pull variants cover the 20-40 mm bore range.
Because this is a 150 mm stroke on an 8 mm rod, the unsupported span is highly susceptible to bending under lateral stress; always pair this SKU with its CA pivot back cover and an external guide to prevent rod-bearing damage. Remember that the fixed rubber bumper softens end-impact but provides no holding force—if air pressure drops, the rod will drift and drop, so deploy an external pilot-operated check valve if the load must be safely suspended. Replacement match: 20 mm bore, 150 mm stroke, G1/8 port, PT thread, CA pivot back cover, S magnet fitted.

- ✓ 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 MBL20X150SCA FAQ
At 0.5 MPa, this 20 mm bore cylinder supplies 157 N push and 132 N pull. Increasing supply to 0.7 MPa yields 220 N push, with a maximum theoretical ceiling of 32 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-stop impact. If your 150 mm stroke demands adjustable pneumatic cushioning for heavier loads, you must select the MBLC variant instead.
