About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200U
The AirTAC MBLC20X200U is a compact double-acting aluminum mini cylinder featuring a tunable pneumatic cushion at both stroke ends. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa, making it suited for light-load positioning over a 200 mm travel. The U flat-end back cover provides a rigid rear mount for straightforward in-line installations.
Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant uses a screw-adjustable needle to decelerate the piston smoothly near the ends, absorbing vibration on faster moves. The riveted rolling-packed aluminum barrel keeps the body light and tight for machine integration, while the Ø8 mm hard-chrome carbon-steel rod resists wear. Note that this specific SKU lacks a built-in magnet, so it cannot host CMSG, DMSG, or EMSG position sensors.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200U Is Used
PCB Shuttle Routing
Moves populated printed circuit boards through an inspection station over 200 mm, using the 157 N push force and tunable cushion to prevent sudden stops that could dislodge SMD components.
Chip Tray Ejection
Pushes empty silicon wafer trays out of a testing cell, where the adjustable end-of-stroke deceleration protects the rigid U flat-end mount from impact shock during high-frequency cycling.
Label Applicator Feed
Advances a label feed mechanism in a compact packaging machine, relying on the lightweight riveted aluminum barrel to fit within tight tooling clearances while accurately indexing labels.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X200U the Right Cylinder?
For sizing flexibility, stepping down to the smaller bore is not an option as 20 mm is the smallest available AirTAC mini cylinder. If your application requires more force, stepping up to the 25 mm bore yields 245 N push at 0.5 MPa. Choose this MBLC version over the standard MBL when your cycle speeds or payload inertia would overwhelm a simple rubber bumper. Keep in mind the adjustable air cushion only decelerates near the ends; it is not a brake, and a plain double-acting cylinder will drift if air pressure is lost.
This 200 mm stroke uses a G1/8 port and an M8x1.25 rod-end thread. Because the stroke exceeds 300 mm, the small Ø8 mm piston rod becomes vulnerable to bending under side loads; for this length, utilize an external guide rail, select a CA or SDB pivot bracket to absorb misalignment, or switch to an MBLD double-rod cylinder to prevent binding.
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 MBLC20X200U FAQ
At 0.5 MPa, the 20 mm bore provides 157 N push and 132 N pull force; at 0.7 MPa, it provides 220 N push and 185 N pull. The maximum theoretical force is 32 kgf at 1.0 MPa. It uses a G1/8 air port, an M8x1.25 rod-end thread, and a PT (tapered) thread form.
This specific SKU lacks the -S code, meaning it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches. The adjustable air cushion at both ends uses a screw needle to restrict exhaust flow, decelerating the piston smoothly near stroke ends to reduce impact on fast moves; it is a dampener, not a locking brake.
