About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X225SCA
The AirTAC MBLC20X225SCA is a compact double-acting aluminum mini cylinder engineered for tight spaces where precise end-of-stroke control is essential. It features a screw-adjustable pneumatic cushion at both ends, allowing you to tune the deceleration of the 225 mm stroke to match your load and speed, thereby minimizing end-cover impact and vibration. Delivering 157 N of push force at 0.5 MPa, it is built with a riveted rolling-packed aluminum barrel for a lightweight yet durable body.
This specific SKU includes a CA pivot back cover that swings on a pin to accommodate arcing or angular loads, and a built-in magnet (-S) for CMSG, DMSG, or EMSG sensor switches. The Ø8 mm hard-chrome carbon-steel rod utilizes a heterogeneous two-way grease-retaining piston seal to maintain consistent lubrication. Because the 225 mm stroke places leverage stress on the small 8 mm rod, the CA clevis mounting is highly advantageous for preventing side-load binding compared to a rigid flat-end mount.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X225SCA Is Used
PCB Depaneling Router
Drives a cutting head across a 225 mm path, using the adjustable cushion to decelerate the 157 N thrust smoothly at stroke ends without jarring delicate populated circuit boards.
Pivot Arm Diverter
Uses the CA clevis mount to swing a small package diverter gate on a packaging line, absorbing angular loads while the magnet triggers a DMSG sensor to confirm gate position.
Connector Insertion Press
Pushes micro-USB connectors into housings with 132 N pull force, relying on the tunable air cushion to prevent crushing the plastic housing at the end of the rapid extension.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X225SCA the Right Cylinder?
Select this 20 mm bore when an application demands 157 N of push force at 0.5 MPa alongside a 225 mm stroke. If you need less force, step down to the 20 mm bore's smaller alternative is not an option as it is the smallest size, but if you require more thrust, step up to the 25 mm bore which provides 245 N push at 0.5 MPa. Choose the MBLC over the base MBL when cycle speeds are high enough that the fixed rubber bumper would wear prematurely or cause excessive shock.
For replacement, verify the 20 mm bore, 225 mm stroke, G1/8 port, PT thread, CA pivot back cover, and the -S magnet. Note that a plain MBLC does not hold position when air is lost or the valve centers; the rod drifts. The air cushion only decelerates near the ends and is not a lock. For position holding without live air, an external rod lock or pilot-operated check valve is required.
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 MBLC20X225SCA FAQ
This 20 mm bore cylinder uses an Ø8 mm rod with an M8x1.25 thread and a G1/8 port. It generates 157 N push and 132 N pull at 0.5 MPa, 220 N push at 0.7 MPa, and a maximum theoretical force of 32 kgf at 1.0 MPa.
The cushion is a screw-tunable needle valve at both ends that traps exhaust air to decelerate the piston smoothly; it is not a brake or lock. The -S magnet works with AirTAC CMSG reed switches, as well as DMSG and EMSG electronic sensors, to detect rod position.
