6202-2ZN/C3 HT51 Bearing Product Overview & Core Advantages
The 6202-2ZN/C3 HT51 is a single row deep groove ball bearing engineered for high-performance industrial applications. This precision bearing is distinguished by its shielded design (2Z) on both sides, offering superior protection against contamination, and its C3 radial internal clearance, which is optimized for applications with elevated operational temperatures or where interference fits are used. Its snap ring groove on the outer ring facilitates secure and simplified axial location within a housing. Manufactured from high-grade chrome steel and built to ABEC 1 | ISO P0 tolerance standards, it delivers reliable performance, high limiting speed capability, and robust radial load capacity in a compact form factor.
6202-2ZN/C3 HT51 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6202-2ZN/C3 HT51 provides a complete technical specification. Below is a detailed breakdown:
- 6202: Basic model number denoting a single row deep groove ball bearing with a 15mm bore, 35mm OD, and 11mm width.
- 2Z: Signifies that the bearing is shielded on both sides. These non-contact shields protect the internal components from dust and debris while minimizing friction.
- N: Indicates the presence of a snap ring groove on the outer ring, enabling secure axial positioning and simplifying housing design.
- /C3: Denotes a greater than normal radial internal clearance. This is essential for applications involving thermal expansion, heavy interference fits, or where a reduction in operating temperature is desired.
- HT51: Specifies a high-temperature stabilization treatment. This process stabilizes the bearing's microstructure, allowing it to maintain dimensional stability and hardness at continuous operating temperatures up to 120°C.
6202-2ZN/C3 HT51 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel, including rings, balls, and cage, this bearing ensures high strength and durability. Its deep groove raceway geometry is optimized to support significant radial dynamic and static loads (1812 lbf / 843 lbf).
- Enhanced Contamination Protection: The double-shielded (2Z) design effectively seals the bearing against particulate contaminants, extending service life and reliability in demanding environments without the added torque of contact seals.
- Simplified Installation & Axial Location: The integrated snap ring groove allows for easy and secure mounting, preventing axial movement of the outer ring and reducing the complexity and cost of the surrounding housing structure.
- Optimized for Demanding Conditions: The combination of C3 clearance and HT51 heat treatment makes this bearing exceptionally suited for applications prone to thermal expansion, high speeds (up to 20,000 rpm), and elevated ambient temperatures.
6202-2ZN/C3 HT51 Bearing Typical Application Areas
This versatile bearing is ideal for a wide range of applications requiring high speed, reliability, and protection, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Pumps and Compressors
- Material Handling Equipment
- Agricultural and Automotive Auxiliary Machinery
