6004-2RS 20x42x12mm Low-Maintenance Sealed Bearing for High-Power Motors Deep Groove Ball Bearing

Low-Maintenance Bearing for High-Power Motors
The 6004-2RS (20x42x12mm) is sized to support the higher radial loads generated by high-power electric motors, while its RS seal minimizes the need for scheduled maintenance.

Engineered for Demanding Motor Applications
This size is specified where motor output and continuous duty cycles are higher than average, requiring a bearing that maintains performance over extended run times without attention.

Sealed for Long-Term Lubrication Retention
The rubber seal keeps grease in place across long operating hours, reducing the risk of lubricant starvation in motors that run for extended, continuous periods.

Built for Industrial Reliability
With a larger cross-section suited to higher loads, this bearing gives motor manufacturers a dependable option for product lines where uptime and low field-failure rates are priorities.

Support for High-Duty Motor Programs
Load and endurance test data are available to support the reliability qualification that high-power motor manufacturers typically require before production approval. Buyers can request endurance test summaries alongside physical samples during the evaluation stage.
