About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350SU
The AirTAC MBLC50X350SU is a double-acting aluminum mini cylinder featuring a 50mm bore and 350mm stroke, delivering a robust 981N push force at 0.5 MPa. The built-in magnet (-S) enables direct mounting of CMSG reed or DMSG and EMSG electronic sensor switches for precise end-of-stroke detection. A flat-end U back cover provides rigid rear anchoring. This model uses a G1/4 port and a Ø16 hard-chrome carbon-steel rod with an M14x1.5 thread.
Unlike the base MBL with its fixed rubber bumper, this MBLC variant incorporates a screw-adjustable pneumatic air cushion at both ends. Tuning the cushion needle allows you to smoothly decelerate heavy 350mm moves, significantly reducing end-cover impact and vibration. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the heterogeneous two-way grease-retaining piston seal ensures lasting operational friction control.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350SU Is Used
Carton Flap Folding
Drives a 350mm arm to fold heavy corrugated carton flaps on a packaging line, using the adjustable cushion to prevent harsh slamming at high cycle rates.
Injection Mold Ejection
Pushes molded plastic parts out of a tool cavity, relying on the 981N push force and the -S magnet to confirm ejection completion before the mold closes.
Pallet Divider Feeding
Separates wooden pallets in a stacking magazine, utilizing the 50mm bore power and smooth end-of-stroke deceleration to avoid damaging the wood.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350SU the Right Cylinder?
Select this 50mm bore when an application requires 981N of push force at 0.5 MPa. If your load is lighter, stepping down to the 40mm bore provides 628N, whereas stepping up to the 63mm bore yields 1558N. The adjustable air cushion is specifically warranted here over a standard bumper because a 350mm stroke generates significant kinetic energy that would otherwise violently strike the end covers.
Because the stroke is 350mm, the Ø16 rod is highly susceptible to bending under lateral stress. To manage side-load, implement an external linear guide, utilize a pivot bracket, or switch to an MBLD double-rod cylinder. This configuration includes a U flat-end back cover, PT thread, and an -S magnet. Note that the air cushion only decelerates the piston near the stroke ends; it is not a locking brake and will not hold position if air pressure drops.
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 MBLC50X350SU FAQ
This 50mm bore cylinder uses a G1/4 port and delivers a push force of 981N and a pull force of 881N at 0.5 MPa. At 0.7 MPa, the push increases to 1374N. The maximum theoretical force is 200 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps exhaust air to decelerate the piston smoothly before it hits the end cover. You adjust it to match the load and speed of the 350mm stroke, which eliminates the harsh impact a fixed rubber bumper would cause. It is strictly a deceleration device, not a load lock.
