About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200SU
The AirTAC MBLC20X200SU is a double-acting aluminum mini cylinder featuring a 20mm bore and 200mm stroke. It generates 157N of push force and 132N of pull force at 0.5MPa, making it suitable for light-load positioning. Unlike the base MBL series, this variant uses a screw-adjustable pneumatic cushion at both ends to decelerate the piston smoothly near stroke limits, reducing impact wear on faster moves.
This SKU includes a U flat-end back cover for rigid mounting and a built-in magnet (the S code) for use with CMSG reed or DMSG and EMSG electronic sensor switches. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the 20um hard-chrome plating on the carbon-steel rod defends against friction. Note that the cushion only decelerates; it does not lock the load if air pressure is lost.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200SU Is Used
PCB Shuttle Conveyors
Moves populated PCB panels between SMT inspection stations, using the 157N push force and tunable cushion to stop smoothly without jarring delicate solder joints.
Pick-and-Place Heads
Actuates the vertical Z-axis on small chip placement robots, where the built-in magnet triggers a DMSG sensor to confirm the 200mm stroke endpoint.
Carton Flap Folders
Folds lightweight cardboard flaps on high-speed packaging lines, relying on the adjustable air cushion to dampen the rapid 200mm travel and reduce mechanical noise.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200SU the Right Cylinder?
At 0.5MPa, this 20mm bore delivers 157N push and 132N pull. If you need less force, step down to the 16mm bore (not in this series), or if you need more power, step up to the 25mm bore which provides 245N push and 206N pull at the same pressure. Choose the MBLC over the fixed-bumper MBL when operating speeds are high or cycle frequencies are demanding. For position holding without live air, add an external rod lock, as the air cushion is not a brake. This 200mm stroke uses a G1/8 port, an M8x1.25 rod thread, and PT tapered threads. Given the 200mm stroke on an 8mm rod, consider a CA pivot back cover or an external guide to manage side-load and prevent rod bending.
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 MBLC20X200SU FAQ
This 20mm bore cylinder provides 157N push and 132N pull at 0.5MPa, 220N push and 185N pull at 0.7MPa, with a theoretical maximum of 32 kgf at 1.0MPa.
A screw-tunable needle at both ends restricts exhaust air to decelerate the piston near the stroke ends. You tune it to match your load and speed, which protects the end covers from impact—unlike the fixed rubber bumper on the standard MBL series.
