About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X15CA
The AirTAC MBLC20X15CA is a compact double-acting aluminum mini cylinder engineered for very short linear motion. It generates 157 N of push force and 132 N of pull force at 0.5 MPa, making it suitable for high-speed clamping or ejecting small parts. The 15 mm stroke is tightly contained within a riveted rolling-packed aluminum barrel, a construction that saves space and weight compared to traditional tie-rod bodies.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. You tune the needle valve to decelerate the piston smoothly near each stroke end, cutting end-cover impact noise and vibration on rapid cycles. The CA pivot back cover allows the cylinder to swing on a pin, absorbing arcing or angular loads. Note that this specific SKU lacks a built-in magnet, so it cannot support CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X15CA Is Used
PCB Ejector Pins
Provides rapid 15 mm ejection of populated printed circuit boards from test fixtures, using the adjustable cushion to silently decelerate the 157 N push before impact.
Pharmaceutical Carton Flaps
Pivots on its CA clevis to follow a folding arm, tucking packaging flaps on small medical cartons with precise short-stroke force without crushing the cardboard.
Connector Insertion Press
Drives delicate ribbon-cable connectors into PCB headers, where the tunable end-cushion prevents the 8 mm rod from slamming and damaging fragile electronic components.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X15CA the Right Cylinder?
Choose this 20 mm bore when you need 157 N of push force at 0.5 MPa in a highly confined footprint. If your application requires less force, the series does not offer a smaller bore, so you would look outside the MBL family. If you need more power, stepping up to the 25 mm bore increases your push force to 245 N at 0.5 MPa. Select the MBLC over the standard MBL when your cycle speed is high enough that the fixed rubber bumper cannot adequately absorb the kinetic energy.
The CA clevis back cover on this unit is essential for mechanisms where the rod experiences slight lateral deviation during travel, as the pivot prevents binding. Because this SKU does not have the S magnet code, you cannot mount reed or electronic switches for end-of-stroke detection; if you need position feedback, specify an MBLC20X15CAS variant. This cylinder uses a G1/8 port, an Ø8 mm carbon-steel rod with 20 µm hard-chrome plating, and PT thread. The adjustable air cushion only decelerates the piston near the ends; it is not a brake and will not hold the load if air pressure is lost.

- ✓ 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 MBLC20X15CA FAQ
This 20 mm bore cylinder delivers a push force of 157 N and a pull force of 132 N at 0.5 MPa. At 0.7 MPa, the push increases to 220 N, with a theoretical maximum of 32 kgf at 1.0 MPa. It uses a G1/8 port and an M8x1.25 rod-end thread.
The cushion traps a small amount of exhaust air at the end of the stroke, compressing it to decelerate the piston smoothly. You turn a screw needle valve to tune the resistance based on load and speed, which reduces impact and noise compared to a fixed rubber bumper. It only functions near the stroke ends and does not lock the rod in place.
