About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X350SU
The AirTAC MBLC20X350SU is a compact double-acting aluminum mini cylinder engineered for precise linear motion within tight machinery envelopes. Driven by air on both extend and retract strokes, it yields 157 N of push force and 132 N of pull force at 0.5 MPa. The 350 mm stroke provides extended travel for part positioning or ejection tasks, while the G1/8 port and Ø8 carbon-steel rod ensure reliable airflow and rigidity. Because this unit features a built-in magnet (-S), it supports direct mounting of AirTAC CMSG (reed) or DMSG and EMSG (solid-state) sensor switches for exact end-of-stroke detection.
Unlike the base MBL series which relies on a fixed rubber bumper, this MBLC variant utilizes a screw-adjustable pneumatic cushion at both ends. This allows you to tune the end-of-stroke deceleration to match your specific load and velocity, effectively absorbing kinetic energy to protect the end covers and reduce vibration on high-speed moves. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the heterogeneous two-way grease-retaining piston seal maintains consistent lubrication for a long service life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X350SU Is Used
PCB Conveyor Ejection
Pushes populated circuit boards across a 350 mm gap to the next processing station, using the adjustable cushion to stop the fragile assemblies smoothly without impact shock.
Semiconductor Wafer Cassette
Extends to index wafer cassettes inside tight processing equipment, relying on the DMSG electronic sensor to confirm full extension in cleanroom environments.
Packaging Flap Tucking
Drives a lightweight arm to tuck carton flaps over a long 350 mm travel distance, with the cushion needle tuned to prevent bounce at high cycle rates.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC20X350SU the Right Cylinder?
If you are sizing this 20 mm bore actuator, evaluate your kinetic energy: at 0.5 MPa it provides 157 N push and 132 N pull. If your application requires less force and a smaller footprint, the neighboring 16 mm bore is not an option in this series, making 20 mm the most compact choice. Stepping up to the 25 mm bore increases thrust to 245 N push and 206 N pull at 0.5 MPa, offering a sturdier alternative for heavier mass. Choose the MBLC over the standard MBL when cycling speeds are high or the moved mass is substantial enough that a fixed rubber bumper would wear prematurely. Remember that the adjustable air cushion only decelerates the piston near the stroke ends; it is not a brake. A plain double-acting cylinder cannot hold position if air pressure is lost or the valve centers—use an external rod lock for fail-safe holding. Because the 350 mm stroke is relatively long for an 8 mm rod, side-load tolerance is low; utilize a CA pivot back cover, an SDB pivot bracket, or an external guide rail to prevent rod bending and premature seal wear.
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 MBLC20X350SU FAQ
The MBLC20X350SU operates on filtered air from 0.15 to 1.0 MPa. At 0.5 MPa it provides 157 N push and 132 N pull force. At 0.7 MPa it yields 220 N push and 185 N pull. 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 pocket of exhaust air to decelerate the piston smoothly near the stroke ends, protecting the end covers from impact. It must be adjusted based on your load and speed. It is strictly a deceleration device and cannot lock or hold the load mid-stroke or during a power loss.
