About the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X75-CA
The AirTAC MBL20X75-CA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa, making it well-suited for light-duty 75 mm linear movements. The riveted rolling-packed barrel keeps the body light and small, though it is not designed to be disassembled like a tie-rod cylinder.
This specific SKU features a CA pivot back cover that swings on a pin to accommodate arcing or angular loads. Internally, a heterogeneous two-way piston seal retains grease for long service life, while the Ø8 mm carbon-steel piston rod features 20 μm hard-chrome plating for wear resistance. Note that because this configuration lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.

Where the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X75-CA Is Used
PCB Depanelling Router
Drives a light cutting head through 75 mm of travel to singulate printed circuit boards, utilizing the CA pivot to maintain tool alignment during slight arcing.
IC Tube Sorting Divert
Actuates a small flap to route empty integrated circuit tubes, where the 157 N push force easily overcomes the tube weight and the pivot mount absorbs side shock.
Microplate Lid Lifter
Pries thin polymer lids off assay plates in a lab automation cell, benefiting from the compact aluminum body to fit between closely spaced robotic gantries.
Is the Airtac MBL Aluminum Alloy Mini Cylinder MBL20X75-CA the Right Cylinder?
With a 75 mm stroke, this 20 mm bore cylinder provides 157 N push at 0.5 MPa. If you need less force, there is no smaller MBL bore available, but if your application requires more power, stepping up to the 25 mm bore yields 245 N push at 0.5 MPa. If your design needs adjustable end-of-stroke cushioning rather than the standard fixed rubber bumper, select the MBLC variant. If a spring return is required, consider the MSBL or MTBL single-acting models.
Because this is a double-acting cylinder, it does not hold its load when air pressure is lost or the valve is centered; the rod will drift. Use an external rod lock or pilot-operated check valve if the load must be held without live pressure. This SKU uses a G1/8 port with PT tapered threading and a CA clevis mount.
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 MBL20X75-CA FAQ
This 20 mm bore cylinder has a G1/8 port. It generates 157 N push and 132 N pull at 0.5 MPa, 220 N push at 0.7 MPa, and a maximum theoretical force of 32 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion (which requires the MBLC variant). Additionally, this specific SKU lacks the -S magnet suffix, so it cannot accept CMSG, DMSG, or EMSG position sensors.
