6800-ZZ Deep Groove Ball Bearing

Product Introduction

The 6800-ZZ is a high-performance deep groove ball bearing featuring double metal shields (ZZ) on both sides. With a bore diameter of 10mm, outer diameter of 19mm, and width of 5mm, this miniature bearing is engineered for applications requiring compact size, low friction, and reliable operation at moderate to high speeds. Manufactured from premium GCr15 chrome steel (AISI 52100 equivalent), the 6800-ZZ delivers exceptional wear resistance and extended service life across a wide range of industrial and commercial applications.

Product Features

• Double Metal Shielded (ZZ): Non-contact metal shields on both sides provide excellent protection against dust and contaminants while maintaining low torque and high-speed capability.
• Premium Chrome Steel: Manufactured from GCr15 (AISI 52100) bearing steel, heat-treated for optimal hardness (HRC 60-64) and superior fatigue resistance.
• Precision Ground Raceways: Computer-controlled grinding ensures ultra-smooth raceway surfaces for reduced vibration, lower noise, and enhanced rotational accuracy.
• Low Noise Rating: Low noise level standards, making it suitable for noise-sensitive applications such as electric motors and household appliances.
• Pre-Lubricated: Factory-filled with premium lithium-based grease for maintenance-free operation, ready to use out of the box.
• High Precision Grade: High precision standards, ensuring consistent dimensions and reliable interchangeability.
• Compact & Lightweight: Thin-section design with 10x19x5mm dimensions and approximately 5 grams weight, ideal for space-constrained applications.
