Product Introduction

Axial currents readily cause electrolytic corrosion between bearing rolling elements and raceways, accelerating grease degradation. High-frequency currents can form circuits through stray capacitance, significantly increasing the risk of equipment damage when paired with variable frequency drives. This poses a severe threat to the safety of motors, generators, and similar equipment. Insulated bearings are specifically designed to block shaft currents. Utilizing precision plasma spraying technology, a high-quality aluminum oxide insulating layer is applied to the inner or outer ring surface. Compared to other insulation solutions, this approach combines high reliability with cost-effectiveness.

 

Insulation Performance

The insulation layer is produced via precision plasma spraying, allowing selection of inner or outer ring insulation as required. Insulation resistance reaches 200MΩ-400MΩ, effectively blocking shaft current conduction.

 

Technical Advantages

Effectively protects bearings from electrical damage, significantly extending equipment lifespan;

Identical dimensions and core technical parameters to standard bearings, enabling direct interchangeability;

Durable and wear-resistant insulation coating suitable for conventional installation and operating conditions.

 

Application Fields

Widely applied in railways, electric motors, generators, wind energy, construction, industrial pumps, and other sectors.
