Why is a 130 mm centering diameter relevant for machine alignment and bearing load distribution?

It helps concentric mounting for reducing shaft misalignment and bearing side-loads under cyclic torque. It improves lifecycle of lifetime-lubricated bearings and maintains encoder geometry for sustaining repeatable accuracy across duty cycles.

What application domains best leverage the 57 Nm standstill torque and 1,500 min⁻¹ nominal speed of MDD115D-N-015-N2L-130PA2?

These values suit indexers, unwind/rewind axes and axis drives in packaging, printing, textile webs, robotic handling and tool feeds requiring steady holding with controlled ramping. Its torque/speed pairing supports consistent throughput and registration.

How does the keyed shaft with shaft seal on MDD115D-N-015-N2L-130PA2 aid coupling reliability and ingress protection?

It ensures torque transmission without slip under repeated reversals, while the seal limits lubricant washout and particle ingress at the front end. It stabilizes backlash behavior and reduce maintenance interventions.

What is the role of the 60 Nm blocking/holding brake in MDD115D-N-015-N2L-130PA2 during E-stop and vertical-axis retention?

The electrically released brake generates static torque to hold gravity or process loads during power loss for preventing drift. It supports safe stops in Z-axes, loaders and turret stations until drives regain control.

How does standard balancing and housing affect vibration behavior and spectral content on MDD115D-N-015-N2L-130PA2?

The standard balancing limits unbalance, curbing excitation at fundamental and harmonic frequencies, which protects bearings and encoder. Its standard sealed housing maintains stiffness and thermal paths for predictable dynamic response under motion profiles.
