About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X100SU
The AirTAC MBLC20X100SU is a compact double-acting aluminum mini cylinder engineered for tight spaces, delivering 157 N of push force at 0.5 MPa. The 100 mm stroke suits small-part positioning, and the riveted rolling-packed aluminum barrel keeps the body light without needing a bulky tie-rod assembly. A heterogeneous two-way grease-retaining piston seal works with the 20 um hard-chrome plated carbon-steel rod to ensure consistent low-friction cycling.
Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic air cushion at both ends. Tuning the needle decelerates the piston smoothly near each stroke end, cutting end-cover impact and vibration on faster moves. The U flat-end back cover provides rigid rear mounting, while the built-in magnet (-S) enables position detection with AirTAC CMSG, DMSG, or EMSG sensor switches.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X100SU Is Used
PCB Pick & Place
Drives a small 100 mm vertical pick stroke for electronic component placement, using the adjustable cushion to prevent sudden stops that could dislodge delicate parts.
Connector Insertion
Pushes ribbon connectors into sockets with 157 N of force, relying on the rigid U back cover to maintain alignment in dense packaging machinery.
Pharma Tray Loading
Actuates a diverter arm for small medical vials, where the built-in magnet confirms the end of stroke for a CMSG reed switch before the next cycle.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X100SU the Right Cylinder?
Choose this 20 mm bore when you need 157 N push force at 0.5 MPa in a compact footprint. If your application requires less force, the smaller 16 mm class drops output, but stepping up to the 25 mm bore increases thrust to 245 N at 0.5 MPa. Select the MBLC over the standard MBL when cycle speeds are high enough that a fixed rubber bumper cannot adequately absorb the impact. The replacement match for this SKU is bore 20, stroke 100, PT thread, U flat-end back cover, and an S magnet. Note that a plain double-acting cylinder does not hold position if air pressure drops; use an external rod lock for fail-safe holding.
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 MBLC20X100SU FAQ
This 20 mm bore cylinder provides 157 N push and 132 N pull at 0.5 MPa. At 0.7 MPa, push increases to 220 N and pull to 185 N. The maximum theoretical force is 32 kgf at 1.0 MPa. It uses a G1/8 port and an M8x1.25 rod thread.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly near the stroke ends, reducing impact noise on fast cycles. It is not a locking brake. Because this SKU includes the -S magnet, it supports AirTAC CMSG reed switches as well as DMSG and EMSG electronic solid-state sensors for position detection.
