Electric motor failures often trace back to substandard bearings—premature wear, excessive noise, and unexpected shutdowns disrupt production schedules and inflate maintenance costs. Sourcing genuine high-precision bearings with consistent quality can be challenging, especially when balancing MOQ requirements and delivery timelines.
Our Deep Groove Ball Bearings Koyo 6004 address these pain points with precision-engineered solutions for electric motors. As a professional bearing supplier with decades of export experience, we ensure each 20x42x12mm bearing meets P0-P4 precision standards, supporting stable operation in demanding industrial environments. Whether you need open, Zz shielded, or 2RS sealed variants, our灵活 MOQ policy (1 piece for standard bearings) and 3-5 day sample delivery keep your production on track.
This Koyo 6004 bearing excels in high-speed electric motor scenarios, where its 20mm bore diameter and 42mm outer diameter balance load capacity with compact design. The 12mm width provides rigid support for rotating shafts, while Z2-Z3-Z4 vibration grades minimize noise in residential and commercial appliances. In automotive auxiliary motors, the bearing’s grease lubrication ensures reliable performance across temperature fluctuations, reducing the need for frequent maintenance.
Precision rating directly impacts motor performance: P4 grade bearings reduce rotational runout by up to 50% compared to standard P0, enhancing energy efficiency and extending motor lifespan. The Z3V3 vibration class limits operational noise to below 45dB, critical for office equipment and household appliances. Seal options cater to specific environments—2RS seals offer superior dust and moisture resistance for outdoor applications like agricultural irrigation motors, while open designs optimize heat dissipation in high-temperature industrial settings.
Evite Costos Ocultos de Rodamientos Falsificados
Non-genuine Koyo bearings may save upfront costs but often fail within 3-6 months, leading to motor breakdowns that cost 10x the bearing price in repairs and downtime. Our products adhere to ISO 9001:2015 quality standards, with full-process production supervision and dimensional testing in our in-house laboratory. Each bearing undergoes noise and vibration testing to ensure compliance with ABMA and DIN specifications, delivering predictable performance and lowering total cost of ownership.
With 18 years of manufacturing experience, we serve brand owners and industrial buyers across Europe, North America, and Southeast Asia. Our ISO 14001 environmental certification ensures sustainable production practices, while our professional R&D team provides free technical guidance on bearing selection and installation. We maintain large inventories to support bulk orders with 5-15 day delivery, and offer a 12-month warranty with free replacement for qualified defective products—no hidden clauses, just reliable service.
