About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X100SCA
The AirTAC MBLC20X100SCA is a compact, double-acting aluminum mini cylinder engineered for tight spaces where standard ISO 6432 bodies will not fit. It produces 157 N of push force and 132 N of pull force at 0.5 MPa from a 20 mm bore. The 100 mm stroke suits short indexing movements. Unlike the base MBL which relies on a fixed rubber bumper, this MBLC variant features a screw-adjustable pneumatic cushion at both stroke ends. Tuning the needle decelerates the piston smoothly near the end caps, cutting impact noise and vibration on faster cycles.
This specific SKU includes a CA pivot clevis back cover that swings on a pin to accommodate arcing or angular loads, preventing rod binding. It also carries the -S code for a built-in magnet, enabling position detection via CMSG reed or DMSG and EMSG solid-state sensor switches. The riveted rolling-packed aluminum barrel keeps the frame light, while the 8 mm carbon-steel rod features 20 um hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for low-friction operation.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X100SCA Is Used
PCB Shuttle Indexing
Drives a 100 mm shuttle stroke on a PCB conveyor using 157 N of push force, where the adjustable cushion prevents jarring stops that could dislodge delicate surface-mount components.
Chip Tray Handling
Extends a pivot-mounted pick arm via the CA clevis to route semiconductor wafers, using the DMSG sensor to confirm full extension before the robot unloads the tray.
Pouch Diverter Gate
Pivots a lightweight sorting flap on a packaging line; the compact 20 mm frame fits within tight conveyor side-guards while cushioning the 100 mm arc.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X100SCA the Right Cylinder?
When sizing this 20 mm bore, step down to the smaller 16 mm bore for lighter duties, or step up to the 25 mm bore which yields 245 N push at 0.5 MPa for heavier loads. Choose this MBLC over the fixed-bumper MBL when your application runs at high speeds or cycles frequently and needs tunable end-of-stroke deceleration. The adjustable air cushion only slows the piston near the ends; it is not a brake. A plain MBLC will not hold position if air is lost or the valve centers, so add an external rod lock for fail-safe holding. To replace this unit exactly, match the 20 mm bore, 100 mm stroke, G1/8 port, PT thread, CA pivot 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 MBLC20X100SCA FAQ
At 0.5 MPa it provides 157 N push and 132 N pull; at 0.7 MPa it provides 220 N push. The maximum theoretical force is 32 kgf at 1.0 MPa.
A screw-tunable needle at both stroke ends restricts exhaust air to decelerate the piston smoothly before it hits the end cover. You tune it to match the load and speed, which is critical for high-frequency cycles where a fixed rubber bumper would fail.
