Prevent Premature Bearing Failures: The Ultimate Solution to Eddy Currents with Schaeffler Series J20G.

At the heart of industries such as rail transport, wind energy and drive technology, the reliability of rolling bearings is crucial. However, the growing demand for efficiency and power has increased a silent risk: eddy currents. These currents, generated by electrical voltage in systems, can wreak havoc on bearings, leading to premature failure and costly downtime. Find out how Schaeffler’s J20G series, with its advanced isolation technology, is revolutionising bearing protection in heavy industry.

Eddy Currents and Bearing Failures

Stray currents, generated by electrical voltage between bearing rings, are the silent enemy of your equipment. These currents can degrade lubricant, damage rolling elements and raceways, and ultimately lead to premature failure. The consequences include:

• High maintenance costs: Frequent repairs and replacements.
• Unplanned downtime: Production losses and delays.
• Reduced equipment life: Premature wear of components.

Electrically Insulated Bearings of the J20G Series

Schaeffler has developed the J20G series, a range of bearings with improved electrical insulation that offers superior protection against eddy currents. The key to its effectiveness lies in the Insutect A coating, based on aluminium oxide applied by plasma spraying.

Key Benefits for Industry:

• Superior protection: Insutect A coating minimises the risk of eddy current damage, extending bearing life.
• Reduced operating costs: By preventing premature failure, the J20G series optimises maintenance cycles and reduces costs.
• Increased uptime: Bearing reliability translates into continuous, efficient production.
• Strength and durability: Designed to withstand heavy loads and extreme conditions in industrial applications.
• Application versatility: Available in a variety of variants to suit specific industry needs.

Outstanding technical characteristics:

• High wear resistant aluminium oxide coating.
• Excellent thermal conductivity for efficient heat dissipation.
• DIN 616 compliance for easy interchangeability.
• Hybrid bearing options with ceramic rolling elements for high insulation applications.

Schaeffler has developed the J20G series, a range of bearings designed to meet the challenges of industry. Its advanced insulation technology and robust design ensure superior protection against eddy currents, maximising reliability and minimising costs.
