Kundenspezifische Hochgeschwindigkeits-Hybrid-Keramik-Rillenkugellager für RC-Modellautomaschinen
Standard Specifications & Options:
Sizes: Available in standard deep groove ball bearing series (e.g., 60-series, 62-series, 63-series) with bore diameters from small precision sizes up to common industrial dimensions.
Precision Grades: Offered in standard ABEC 1 (P0) up to higher precision grades (ABEC 3/P6, ABEC 5/P5) for applications requiring exceptional running accuracy.
Clearance: Standard radial clearance (C0, CN) is available; other clearance groups can be specified.
Seals/Shields: Options include open, steel shields (ZZ), or rubber seals (RS, 2RS) for contamination protection, though the choice of seal must account for the potential for higher speeds.
Product Overview
Engineered for performance-critical applications, our Hybrid Deep Groove Ball Bearings are precision components designed to surpass the limitations of all-steel bearings. Below are the detailed specifications and benefits that make them a superior choice for demanding industrial and commercial uses.
Core Construction & Materials:
These bearings feature precision-ground rings made from high-carbon chromium steel (SAE 52100), ensuring a robust and durable raceway structure. The defining component is the set of rolling elements: high-grade ceramic balls(Si3N4/Zro2) . This material is significantly harder, lighter (approximately 60% lighter than steel), and more resistant to wear and corrosion than traditional steel balls.
Key Features:
High-Speed Operation
The lower density of ceramic balls drastically reduces centrifugal force, allowing these hybrid deep groove ball bearings to operate at much higher speeds (typically 20-40% higher) with less heat generation and lower vibration.Extended Service Life
The extreme hardness and smooth surface finish of the ceramic balls minimize wear on both the balls and the steel raceways, leading to a dramatically longer operational lifespan, especially in clean, well-lubricated environments.- Corrosion & Insulation Resistance
The ceramic balls are inert and do not rust. This hybrid construction also provides a degree of electrical insulation, helping to prevent damage from electrical arcing in applications like electric motors. - Reduced Maintenance
They perform excellently in marginal lubrication conditions and generate less friction, which can extend lubrication intervals and reduce overall system energy consumption.
Applications
High-speed electric motors and spindles
Precision machine tool shafts
Turbomachinery and pumps
Applications requiring extended life with minimal maintenance
Environments where corrosion or electrical insulation is a concern
