Roulements à billes à gorge profonde en céramique hybrides à grande vitesse personnalisés pour machine de voiture modèle RC
Spécifications standards & Possibilités:
Sizes: Available in standard deep groove ball bearing series (par ex., 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.
Présentation du produit
Engineered for performance-critical applications, our Hybrid Deep Groove Ball Bearings are precision components. They are designed to surpass the limitations of all-steel bearings. Donc, they are widely used in demanding industrial and commercial environments.
Core Construction & Matériels
These bearings use precision-ground rings made from high-carbon chromium steel (SAE 52100). This ensures a strong and durable raceway structure.
En outre, the rolling elements are high-grade ceramic balls (Si3N4/ZrO2). These ceramic balls are significantly harder and lighter. In fact, they are about 60% lighter than steel balls. De plus, they offer higher resistance to wear and corrosion.
Principales fonctionnalités
High-Speed Operation
The lower density of ceramic balls reduces centrifugal force. Par conséquent, these hybrid deep groove ball bearings can operate at much higher speeds.
Typiquement, speed increases by 20–40%. En même temps, heat generation is reduced. Vibration is also lower.
Extended Service Life
Ceramic balls have extreme hardness and a smooth surface finish. Donc, they reduce wear on both balls and steel raceways.
En outre, this structure significantly extends operational lifespan. This is especially true in clean and well-lubricated environments.
Corrosion & Insulation Resistance
Ceramic balls are chemically inert. Donc, they do not rust.
En outre, this hybrid structure provides electrical insulation. Par conséquent, it helps prevent damage caused by electrical arcing in electric motors.
Reduced Maintenance
These bearings perform well even under marginal lubrication conditions. En outre, they generate lower friction.
Donc, lubrication intervals can be extended. En même temps, overall system energy consumption is reduced.
Applications
These bearings are widely used in multiple high-performance systems.
- High-speed electric motors and spindles
- Precision machine tool shafts
- Turbomachinery and pumps
- Systems requiring long service life with minimal maintenance
- Environments with corrosion risk or electrical insulation requirements
