About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350U
The AirTAC MBLC50X350U is a double-acting, compact aluminum mini cylinder engineered with a 50mm bore and 350mm stroke. It generates 981N of push force and 881N of pull force at 0.5MPa, scaling to a maximum 200kgf at 1.0MPa. Because this model lacks the -S magnet code, it cannot accept a CMSG, DMSG, or EMSG position sensor switch. The U suffix denotes a rigid flat-end back cover for straightforward inline mounting.
This unit utilizes a screw-adjustable pneumatic air cushion at both stroke ends rather than a fixed rubber bumper. You tune the cushion needle to smoothly decelerate the piston near the end covers, mitigating impact shock on heavier or faster transfers. The riveted rolling-packed aluminum barrel keeps the body light and compact, while the Ø16mm carbon-steel rod features a 20um hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for durable service.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350U Is Used
Pallet Transfer Line Diverter
Pushes heavy pallets across a 350mm gap at high cycle rates. The adjustable air cushion prevents the 981N thrust from slamming the end covers during rapid routing.
Warehouse Vertical Lift Gate
Actuates a 350mm safety gate on a multi-level storage elevator. Tunable pneumatic deceleration ensures the heavy panel closes smoothly without bouncing.
Injection Mold Ejector
Drives a secondary parts ejector over a 350mm mold depth. The riveted aluminum body fits tight press ceilings while delivering 881N of pull force at 0.5MPa.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X350U the Right Cylinder?
Select this 50mm bore when an application requires substantial thrust—981N push at 0.5MPa—over a long 350mm travel. If your load is lighter, stepping down to a 40mm bore yields 628N push, whereas moving up to a 63mm bore provides 1558N push for highly demanding presses. Choose this MBLC variant over the base MBL when cycle speeds or moving masses exceed what a fixed rubber bumper can absorb. Note that the adjustable air cushion only decelerates the piston near the ends; it is not a brake and will not hold the rod in place if air pressure is lost or the valve centers. For secure holding without live air, an external rod lock or pilot-operated check valve is required.
With a 350mm stroke, the Ø16mm piston rod is highly susceptible to bending under side loads. To prevent premature seal failure and rod scoring, do not let this cylinder carry lateral forces alone. Implement an external linear guide, switch to a CA or SDB pivot bracket to accommodate arcing loads, or select an MBLD double-rod cylinder for maximum torsional rigidity. The porting is G1/4, and the rod-end thread is M14x1.5.
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 MBLC50X350U FAQ
At 0.5MPa, this 50mm bore cylinder provides 981N of push force and 881N of pull force. At 0.7MPa, the push force increases to 1374N. The maximum theoretical force is 200kgf at 1.0MPa operating pressure.
No. Because the model code MBLC50X350U lacks the -S suffix, it is manufactured without a built-in magnet and cannot interface with AirTAC CMSG, DMSG, or EMSG sensor switches. You would need the MBLC50X350SU variant for position detection.
