63806 Bearing Product Overview & Core Advantages
The 63806 metric ball bearing is a single row deep groove ball bearing designed for high-performance radial load applications. Engineered with precision ABEC-1 tolerances, it offers reliable operation and consistent performance. Its compact design, featuring a 30mm bore and 42mm outside diameter, makes it an ideal solution for space-constrained assemblies requiring robust radial dynamic load capacity of 1021 lbf. Manufactured from high-grade chrome steel with a stainless steel cage, this bearing provides excellent durability and is suitable for a wide operating temperature range from -30°C to 110°C.
63806 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 63 | Series designation indicating deep groove construction and specific dimensional series |
| 806 | Bore size code representing 30mm bore diameter (806 × 5 = 4030, indicating 30mm) |
| Open | No seals or shields, allowing for maximum speed capability and custom lubrication options |
63806 Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway profile enables excellent radial load capacity while accommodating moderate axial loads in both directions, making it versatile for various applications.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional controls (bore tolerance: -0.01mm to 0, OD tolerance: -0.011mm to 0) ensuring consistent performance and easy installation.
High-Speed Capability: The stainless steel cage and open design contribute to a limiting speed of 18,000 rpm, suitable for high-speed operations when properly lubricated.
Standard Internal Clearance: Features C0 radial clearance (0.006mm to 0.020mm), providing optimal performance for most general applications under normal operating conditions.
Material Excellence: Constructed from chrome steel rings and chrome steel balls for superior wear resistance and fatigue life, complemented by a corrosion-resistant stainless steel cage.
