About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X20SU
The AirTAC MBLC20X20SU is a compact double-acting aluminum mini cylinder engineered for short 20 mm strokes in tight assemblies. It delivers 157 N of push force and 132 N of pull force at 0.5 MPa. Unlike the base MBL series, this variant features a screw-adjustable pneumatic cushion at both ends. You tune the needle valves to smoothly decelerate the piston near each stroke limit, which is critical for protecting the end covers on high-frequency or rapid positioning moves.
This model includes a built-in magnet (-S) for rod position detection using AirTAC CMSG (reed), DMSG, or EMSG (electronic) sensor switches. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the 20 µm hard-chrome plated carbon-steel rod pairs with a heterogeneous two-way grease-retaining piston seal for durable, low-friction operation. It uses a G1/8 port, an M8x1.25 rod-end thread, and a rigid U flat-end back cover.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X20SU Is Used
PCB Pick-and-Place
Ideal for short 20 mm vertical positioning of delicate printed circuit boards where the tunable air cushion prevents harsh end-stop impacts on high-speed pickers.
Connector Insertion
Provides the 157 N push force needed to seat electronic ribbon connectors, using the built-in magnet to confirm insertion depth via a DMSG sensor.
Pharmaceutical Sorting
Handles small vial rejection tasks on compact packaging lines, where the lightweight aluminum body and 30-800 mm/s speed range keep pace with rapid indexing.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X20SU the Right Cylinder?
Choose this 20 mm bore when you need precise, cushioned motion in a compact footprint. If your application requires even less force, stepping down is not an option as 20 mm is the smallest available size. If you need more power, the 25 mm bore provides 245 N of push force at 0.5 MPa. Select the MBLC over the standard MBL when your cycle speeds push the limits of a fixed rubber bumper. Keep in mind the adjustable air cushion only decelerates the piston near the ends; it is not a brake and will not hold the load if air pressure drops. For exact replacements, match the 20 mm bore, 20 mm stroke, PT thread, U flat-end cover, and -S magnet.
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 MBLC20X20SU FAQ
At 0.5 MPa, this double-acting cylinder provides 157 N of push force and 132 N of pull force. At 0.7 MPa, the push increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa.
The cushion is a screw-tunable needle valve at both ends that traps a small amount of exhaust air to decelerate the piston before it hits the end cover. You adjust it to match your load and speed, reducing impact noise and wear compared to a fixed rubber bumper. It does not lock the rod in place.
