About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X200SU
The AirTAC MBLC50X200SU is a double-acting, 50 mm bore aluminum mini cylinder delivering 981 N of push force and 881 N of pull force at 0.5 MPa. Unlike the base MBL series, this variant features a screw-adjustable pneumatic cushion at both stroke ends, allowing you to tune the end-of-travel deceleration to match heavier loads and faster cycling speeds. The 200 mm stroke is well-suited for medium-travel positioning tasks that require controlled stoppage to protect machinery.
This model includes a built-in magnet (the S code) for use with AirTAC CMSG reed or DMSG and EMSG solid-state sensor switches to track rod position. The U code denotes a rigid flat-end back cover for straightforward inline mounting. The riveted rolling-packed aluminum barrel keeps the body compact and lightweight, while the 20 um hard-chrome plating on the carbon-steel rod pairs with a heterogeneous two-way grease-retaining piston seal for durable, low-friction operation.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X200SU Is Used
Pallet Transfer Diverter
Provides 981 N of push at 0.5 MPa to deflect heavy pallets between conveyor lanes, using the 200 mm stroke and adjustable cushions to soften the impact of rapid routing changes.
Injection Mold Ejection
Knocks out molded plastic parts using 881 N of pull force, relying on the tunable air cushion to decelerate the 16 mm rod smoothly before it strikes the rear cover during fast cycle rates.
Carton Flap Folder
Drives a mechanical arm over a 200 mm travel to fold heavy corrugated flaps on packaging lines, benefiting from the compact riveted aluminum body in tight machine clearances.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X200SU the Right Cylinder?
If your application requires less force, stepping down to the 40 mm bore yields 628 N of push at 0.5 MPa, whereas moving up to the 63 mm bore provides 1558 N. Choose this MBLC version over the fixed-bumper MBL when your cycle speeds exceed what a rubber stop can absorb, but remember the air cushion only decelerates near the ends—it is not a brake. A plain double-acting cylinder will drift if air pressure is lost or the valve centers, so add an external rod lock if you need true fail-safe position holding. This exact replacement match is a 50 mm bore, 200 mm stroke, G1/4 port, PT thread, U back cover, with an S magnet. Because the stroke is 200 mm, the 16 mm rod has a relatively low tolerance for side-loading; use an external guide rail or pivot bracket to prevent rod bending on longer moves.
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 MBLC50X200SU FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push increases to 1374 N. The theoretical maximum force is 200 kgf at 1.0 MPa.
The cushion is a screw-tunable needle valve at both ends that traps a pocket of air to decelerate the piston smoothly near the end of travel, preventing hard impacts on fast or heavy moves. It is strictly a deceleration device and not a lock; the cylinder cannot hold a position if air supply is lost or exhausted.
