A technical analysis comparing Ceramic Coated and Hybrid bearings for industrial motors. This guide covers the cost advantages of coatings, mechanical fragility, and why the “Capacitor Effect” matters in high-frequency applications.

This engineering guide details the criteria for specifying insulated bearings to prevent electrical erosion in motors. It covers critical triggers like VFD usage and motor size (>100 HP), compares protection methods, and outlines industry standards for NDE (Non-Drive End) installation.

This technical guide explores the mechanics of EDM bearing damage (electrical erosion) caused by stray shaft voltages in VFD applications. It outlines critical symptoms such as fluting and pitting, while offering proven prevention strategies like insulated bearings and shaft grounding rings.

This technical analysis explores how VFD-induced common mode voltage and parasitic capacitance create destructive shaft currents (EDM) that lead to premature bearing failure, while offering engineering solutions like grounding rings and hybrid ceramic bearings for mitigation.
