About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X160U
The AirTAC MBLC20X160U is a double-acting aluminum mini cylinder with a 20 mm bore and 160 mm stroke, delivering 157 N of push force at 0.5 MPa. It features a screw-adjustable pneumatic cushion at both ends, allowing you to tune the end-of-stroke deceleration to match your load and speed. This protects the end covers from impact, reducing noise and vibration on faster moves where a fixed rubber bumper would fail.
This U back cover variant provides a rigid flat-end rear mount. The body uses a riveted rolling-packed aluminum barrel for a compact, light profile in tight spaces, while the Ø8 mm carbon-steel rod features 20 µm 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 without modification.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X160U Is Used
PCB Depaneling Ejector
Pushes singulated circuit boards out of a routing fixture over 160 mm. The tuned air cushion ensures the 8 mm rod retracts smoothly without jarring the delicate panel edges.
Connector Pin Insertion
Drives a light 157 N insertion head to press IC pins into sockets. The adjustable end-cushion prevents bounce-back that would skew pin alignment.
Pharmacy Drawer Latch
Actuates a compact locking latch on automated dispensing cabinet drawers. The U flat-end mount bolts rigidly to the frame, while the cushion silences the repetitive click.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X160U the Right Cylinder?
Choose this 20 mm bore when you need 157 N of thrust at 0.5 MPa (220 N at 0.7 MPa) with smooth cushioning over a 160 mm travel. If your application requires less force, the neighboring smaller MBL size does not exist in this series, making 20 mm the most compact option available. If you need significantly more power, step up to the 25 mm bore, which provides 245 N of push force at 0.5 MPa. Because this model lacks the -S magnet, it cannot use AirTAC CMSG reed or DMSG/EMSG electronic switches; confirm if you need position feedback before ordering. The PT tapered port threads match standard Asian pneumatic fittings.
At 160 mm of stroke, the small Ø8 mm rod has limited side-load tolerance. If your load tends to arc or sag, consider using an external guide rail to prevent rod bending and premature seal wear. The adjustable cushion is strictly for decelerating the piston near the stroke ends and will not hold the load in place if air pressure is lost.
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 MBLC20X160U FAQ
This 20 mm bore cylinder provides 157 N push and 132 N pull at 0.5 MPa, 220 N push and 185 N pull at 0.7 MPa, and a maximum theoretical force of 32 kgf at 1.0 MPa. It uses a G1/8 port with PT tapered threads and an M8x1.25 rod-end thread.
A screw needle valve at each end cover traps a small amount of exhaust air to decelerate the piston before it hits the cap. You tune this needle to match your load and speed, which stops end-cover impact and reduces noise. It is a deceleration device, not a brake, and will not hold the load if air pressure drops.
