About the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X50SU
The AirTAC MBLC50X50SU is a double-acting, 50mm bore aluminum mini cylinder with a 50mm stroke. It generates 981N of push force and 881N of pull force at 0.5 MPa, making it well-suited for mid-range actuation tasks. Unlike the base MBL series, this variant uses a screw-adjustable pneumatic cushion at both stroke ends. You tune the needle to smoothly decelerate the piston, cutting impact shock and vibration on faster moves. The cushion only slows the rod near the ends; it is not a load lock.
This SKU features a U-type flat-end back cover for rigid mounting and a built-in magnet (the S code) for position detection. The magnet works seamlessly with AirTAC CMSG reed switches or DMSG and EMSG solid-state electronic sensors. The riveted rolling-packed aluminum barrel keeps the body compact for tight spaces, while the Ø16 carbon-steel rod features a 20 µm hard-chrome plating paired with a heterogeneous two-way grease-retaining piston seal for long service life.

Where the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X50SU Is Used
Injection Mold Ejection
Provides 981N of push force to eject formed plastic parts from injection molds, using the adjustable cushion to prevent end-cover impact during rapid ejection cycles.
Package Sorting Diverter
Actuates a diverter arm on a packaging conveyor, utilizing the 50mm stroke and DMSG electronic sensor feedback to route heavy cartons smoothly without bouncing.
PCB Test Handler
Drives an electronic test head down onto printed circuit boards, relying on the 881N pull force and cushioned retraction to protect delicate test pins from sudden shock.
Is the Airtac MBLC Aluminum Alloy Mini Air Cylinder MBLC50X50SU the Right Cylinder?
If your application requires less force, stepping down to the 40mm bore yields 628N of push force at 0.5 MPa. If you need more power, stepping up to the 63mm bore provides 1558N of push force. Choose this MBLC model over the fixed-bumper MBL when your machine cycles quickly or moves a heavier mass that would prematurely wear a rubber absorber. For replacement matching, ensure you specify the 50mm bore, 50mm stroke, G1/4 port, PT thread, U flat-end back cover, and the S magnet option. Note that a plain double-acting cylinder will not hold position if air pressure drops or the valve centers; the rod will drift, so use an external rod lock for fail-safe holding.
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 MBLC50X50SU FAQ
At 0.5 MPa, the push force is 981N and the pull force is 881N. At 0.7 MPa, the push force reaches 1374N. The maximum theoretical force is 200 kgf at 1.0 MPa.
A screw-tunable needle at both ends traps a pocket of exhaust air to decelerate the piston smoothly near the stroke ends. You adjust it to match your load and speed, which reduces noise and end-cover wear compared to a fixed rubber bumper.
