About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350SCA
The AirTAC MBLC50X350SCA is a double-acting, compact aluminum mini cylinder engineered for demanding actuation. It generates 981 N of push force and 881 N of pull force at 0.5 MPa, scaling to 1374 N push at 0.7 MPa. The 350 mm stroke suits extended travel operations, while the CA pivot back cover allows the body to swing on a pin to absorb angular motion.
Unlike the base MBL series with its fixed rubber bumper, this MBLC model features a screw-adjustable pneumatic air cushion at both ends. This allows you to precisely tune end-of-stroke deceleration, protecting the end covers from impact during fast, heavy 350 mm traverses. The riveted rolling-packed aluminum barrel keeps the unit light and compact, and the -S code indicates a built-in magnet for CMSG, DMSG, or EMSG sensor switches.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350SCA Is Used
Pallet Swing Diverter
Uses the 350 mm stroke and CA pivot to swing heavy pallets on a packaging line, relying on the 981 N push force and tunable cushion to halt the 350 mm traverse smoothly.
CNC Lathe Door Opener
Extends the full 350 mm to pull a heavy machine tool door wide open, using the adjustable cushion to prevent slamming at the end of travel during high-frequency automated cycles.
Vertical Parts Elevator
Lifts loaded material trays vertically, where the 881 N pull force retracts the rod and the cushion needle is dialed in to softly catch the descending load before the end cap.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350SCA the Right Cylinder?
For sizing context, stepping down to the 40 mm bore reduces the output to 628 N push at 0.5 MPa, while stepping up to the 63 mm bore increases it to 1558 N. Choose this MBLC variant over the standard MBL when your cycle speed or moving mass outpaces a fixed bumper's capability. The 350 mm stroke is substantial for a Ø16 rod; to manage rod bending and side-load, leverage the CA pivot mounting, add an external guide, or consider an MBLD double-rod cylinder. Note that the air cushion only decelerates near the ends and will not hold the load if air pressure drops. The direct replacement match is: 50 mm bore, 350 mm stroke, G1/4 port, PT thread, CA back cover, and -S magnet.

- ✓ 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 MBLC50X350SCA FAQ
At 0.5 MPa, it provides 981 N push and 881 N pull. At 0.7 MPa, it provides 1374 N push. The maximum theoretical force is 200 kgf at 1.0 MPa. It uses a G1/4 port and a Ø16 carbon-steel rod with an M14x1.5 end thread.
The cushion is a screw-tunable needle at both ends that traps exhaust air to decelerate the piston near the stroke limits. You adjust it to match the load and speed, which cuts impact stress on the end covers. It is a deceleration device, not a load lock or brake.
