About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X20SCA
The AirTAC MBLC50X20SCA is a double-acting mini cylinder engineered for compact actuation, delivering 981 N of push force and 881 N of pull force at 0.5 MPa. It features a 50 mm bore, a 20 mm stroke, and a built-in magnet for CMSG, DMSG, or EMSG sensor switches. The CA pivot/clevis back cover allows the body to swing on a pin, accommodating arcing loads, while the PT thread form ensures a tapered pneumatic seal.
Unlike the fixed rubber bumper of the base MBL, this MBLC variant utilizes a screw-adjustable pneumatic cushion at both ends to smoothly decelerate the piston near stroke limits. The 20 mm travel is exceptionally short, making the unit ideal for high-speed, high-frequency repetitive tasks. Its riveted rolling-packed aluminum barrel keeps the envelope small, and the 20 µm hard-chrome plating on the carbon-steel rod defends against wear.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X20SCA Is Used
Stamping Press Ejection
Uses the 981 N push force to knock small stamped metal parts out of a die quickly, relying on the cushion to absorb the sudden end-of-stroke impact during rapid cycling.
Pivot Arm Diverter
Leverages the CA pivot back cover to swing a diverter blade on a packaging conveyor, handling angular movement without binding across the 20 mm travel.
PCB Shuttle Positioning
Employs the built-in magnet with a DMSG solid-state sensor to confirm the 20 mm retracted position of a board shuttle, fitting into tight electronics assembly machinery.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X20SCA the Right Cylinder?
For applications needing less force, step down to the 40 mm bore (628 N push at 0.5 MPa); if your load requires more, step up to the 63 mm bore (1558 N push at 0.5 MPa). The 50 mm bore uses a G1/4 port and a Ø16 rod. Choose this MBLC model over the base MBL when your short-stroke cycle runs fast or moves enough mass that a fixed bumper would suffer impact damage. Remember that the air cushion only decelerates near the ends; it does not lock the rod, so if you need to hold position without live air, install an external rod lock or pilot-operated check valve.
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 MBLC Aluminum Alloy Mini Air Cylinder MBLC50X20SCA FAQ
At 0.5 MPa, it provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
The CA clevis allows the cylinder to swing on a pin, preventing side-load binding during arcing movements. The screw-adjustable air cushion at both ends lets you tune the deceleration of the 20 mm stroke to protect the end covers from impact, though it does not function as a load lock.
