About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X150SU
The AirTAC MBLC20X150SU is a compact double-acting aluminum mini cylinder featuring a 20mm bore and 150mm stroke. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa, making it suitable for light-duty positioning. Unlike the base MBL, this variant uses a screw-adjustable pneumatic cushion at both ends to decelerate the piston smoothly near stroke limits, cutting impact shock on faster cycles.
This SKU includes a U flat-end back cover for rigid mounting and a built-in magnet for CMSG, DMSG, or EMSG sensor switches. The riveted rolling-packed aluminum barrel keeps the body light for tight spaces, while the Ø8 carbon-steel rod features 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for lasting friction control.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X150SU Is Used
PCB Component Placement
Deploys a 150mm stroke to lower light pick-and-place heads onto electronics assembly lines, using the adjustable cushion to prevent end-cover impact on rapid indexing.
Packaging Flap Folding
Extends 150mm to fold small cardboard carton flaps on high-speed packaging conveyors, relying on the 157 N push force and tunable deceleration for quiet stops.
Textile Yarn Guides
Shifts lightweight yarn guides across weaving machinery; the compact riveted barrel fits narrow loom frames while the magnet tracks rod position for sequence timing.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X150SU the Right Cylinder?
Choose this 20mm bore when you need 157 N of push force at 0.5 MPa. If your load is lighter, the next size down does not exist in this mini series, so you must step up. If you need more power, the 25mm bore provides 245 N of push force at 0.5 MPa. Select the MBLC over the fixed-bumper MBL when your cycle speed or load mass makes rubber impact unacceptable.
This cylinder uses a G1/8 port, an M8x1.25 rod thread, and PT tapered threading. The U flat-end back cover provides a rigid rear mount, while the -S magnet enables electronic position sensing. Remember that the adjustable air cushion only decelerates the piston near the ends; it does not lock the rod or hold position when 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 MBLC20X150SU FAQ
At 0.5 MPa, this 20mm bore cylinder provides 157 N push and 132 N pull force. At 0.7 MPa, it provides 220 N push and 185 N pull. The theoretical maximum holding force is 32 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
A screw-tunable needle valve at both stroke ends traps a small air pocket to decelerate the piston before it hits the cover. You dial the needle to match your load and speed, which reduces vibration and noise. It is a deceleration device, not a mechanical lock, so the rod will drift if air is lost.
