About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X60U
The AirTAC MBLC20X60U is a double-acting aluminum mini cylinder engineered for compact actuation in tight spaces. It features a 20mm bore and 60mm stroke, delivering 157N of push force and 132N of pull force at 0.5MPa. The U designation indicates a rigid flat-end rear cover, providing a straightforward fixed mounting interface for straightforward push-pull tasks.
Unlike the standard bumper-equipped MBL, this MBLC variant incorporates a screw-adjustable pneumatic cushion at both stroke ends. Tuning the needle valve allows you to decelerate the piston smoothly, reducing end-cover impact and vibration on faster cycles. The riveted rolling-packed aluminum barrel keeps the body light, while the Ø8mm carbon-steel rod features 20µm hard-chrome plating to resist wear. 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 MBLC20X60U Is Used
PCB Router Gating
Directs printed circuit boards down the correct processing lane with 157N of push force, relying on the adjustable cushion to stop the 60mm stroke gently without jarring delicate solder joints.
Pick-and-Place Ejector
Pushes small surface-mount components out of a feeder tube in a confined electronics assembly cell, where the compact 20mm barrel fits neatly alongside larger robotic actuators.
Pharmaceutical Carton Flap
Tucks minor flaps on lightweight medicine cartons moving at high speeds, using the tuned end-of-stroke deceleration to prevent denting the cardboard packaging.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X60U the Right Cylinder?
For lower force requirements, stepping down is not an option as 20mm is the smallest available bore in this series. If your application demands more thrust, the next size up is the 25mm bore, which provides 245N of push force at 0.5MPa. Choose the MBLC over the base MBL when your cycle speeds are high enough that a fixed rubber bumper would wear prematurely or cause excessive impact noise. Keep in mind that a plain double-acting cylinder does not hold position if air pressure is lost; the air cushion only decelerates the rod near the ends and acts purely as a brake, not a load lock. This replacement matches bore 20, stroke 60, G1/8 port, PT thread, U flat-end cover, and no magnet.
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 MBLC20X60U FAQ
At 0.5MPa it provides 157N push and 132N pull. At 0.7MPa it provides 220N push and 185N pull. The maximum theoretical force is 32kgf at 1.0MPa, with an operating pressure range of 0.15-1.0MPa and a speed range of 30-800mm/s.
A screw-tunable needle valve at both ends traps a pocket of exhaust air to decelerate the piston before it hits the end cover. You adjust it to match your specific load and speed, which reduces impact noise and wear compared to a fixed rubber bumper. It is a deceleration device, not a mechanical lock.
