About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X10U
The AirTAC MBLC20X10U is a compact double-acting aluminum mini cylinder engineered for short 10 mm movements. It generates 157 N of push force and 132 N of pull force at 0.5 MPa, making it well-suited for tight-space actuation where precise endpoint control is required. Unlike the base MBL, this variant features a screw-adjustable pneumatic cushion at both ends to smoothly decelerate the piston near stroke completion.
This model uses a riveted rolling-packed aluminum barrel for a lightweight, sealed body rather than a rebuildable tie-rod design. The Ø8 mm carbon-steel rod features 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for lasting friction control. Note that this specific SKU lacks a built-in magnet (-S), meaning it cannot support CMSG, DMSG, or EMSG position sensing.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X10U Is Used
PCB Ejector Pins
Provides a rapid 10 mm kick to eject printed circuit boards from test fixtures, using the adjustable cushion to prevent bouncing on delicate solder joints.
Connector Seating
Applies 157 N of force to press-fit small electronic connectors into housings, absorbing the end-of-stroke shock to protect fragile components.
Carton Flap Tucking
Executes a short, fast stroke to tuck inner flaps on small pharmaceutical cartons before sealing, fitting neatly into compact packaging machinery.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X10U the Right Cylinder?
Choose this 20 mm bore when an application demands 157 N of thrust at 0.5 MPa within a very tight 10 mm stroke envelope. If you need less force, there is no smaller bore in this series; if your load requires more power, step up to the 25 mm bore which provides 245 N of push force at 0.5 MPa. The U flat-end back cover provides rigid, straight-line mounting.
The adjustable air cushion is ideal for protecting end covers during rapid, high-frequency cycling, functioning strictly as a deceleration mechanism rather than a load lock. Remember that a plain double-acting cylinder does not hold position if air pressure is lost or the valve centers; use an external rod lock for fail-safe holding. This SKU uses a default PT port thread and cannot accept a sensor switch.
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 MBLC20X10U FAQ
At 0.5 MPa, this 20 mm bore cylinder outputs 157 N push and 132 N pull force. At 0.7 MPa, it outputs 220 N push. The theoretical maximum force is 32 kgf at 1.0 MPa. It uses a G1/8 port and an M8x1.25 rod-end thread.
A screw-tunable needle at both ends traps a small amount of exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust it to match the load and speed, which reduces impact noise and wear on high-frequency 10 mm strokes. It is a damping feature, not a braking or load-holding lock.
