63801 Bearing Product Overview & Core Advantages
The 63801 is a metric single row deep groove ball bearing designed for reliable performance in a wide range of industrial applications. Engineered with precision-ground chrome steel components, this bearing is optimized to carry significant radial loads and moderate axial loads in one direction. Its compact design, featuring a 12 mm bore, 21 mm outside diameter, and a narrow 7 mm width, makes it an ideal solution for space-constrained assemblies. Manufactured to ABEC-1 tolerance standards, it ensures consistent operation and is an excellent choice for applications requiring a balance of cost-effectiveness and dependable performance.
63801 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 63 | Series code indicating a deep groove ball bearing with specific dimensional proportions. |
| 801 | Bore diameter code. The calculation is (801 * 5) = 4005, indicating a 12 mm bore diameter. |
| (No Suffix) | The absence of additional suffixes confirms an open (unsealed) design, a C0 radial internal clearance group, and a standard stainless steel cage. |
63801 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The single row deep groove raceway geometry is engineered to efficiently support high radial dynamic load ratings of 432 lbf, while also accommodating axial loads.
- High-Speed Capability: The standard stainless steel cage provides strength and durability, contributing to a high limiting speed of 36,000 rpm for demanding applications.
- Precision & Consistency: Manufactured to ABEC-1 precision class tolerances, this bearing ensures smooth, low-vibration operation and reliable rotational accuracy.
- Robust Construction: Made from high-grade chrome steel for rings and balls, the bearing offers excellent resistance to wear and a long operational life under standard conditions.
- Clearance & Flexibility: The standard C0 radial internal clearance (0.003mm to 0.018mm) makes it suitable for a wide range of operating conditions and fits.
