6206-ZNRQ66 HT51 Bearing Product Overview & Core Advantages
The 6206-ZNRQ66 HT51 is a single row deep groove ball bearing engineered for high performance in demanding applications. Its primary advantage lies in its ability to efficiently handle radial loads while offering a compact and robust design. A key feature is the snap ring fitted on the outer ring, which simplifies axial location within a housing, enhancing assembly precision and system rigidity. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing ensures reliable operation and is supplied with a shielded design to protect against contaminant ingress, making it a dependable choice for a wide range of industrial machinery.
6206-ZNRQ66 HT51 Bearing Model Code Explained, Specifications & Naming Convention
- 6206: Standard designation for a single row deep groove ball bearing with a 30mm bore and 62mm outside diameter.
- Z: Denotes a shielded (non-contact) seal on one side of the bearing, providing protection against large particles while minimizing friction.
- N: Signifies a snap ring groove on the outer ring.
- R: Indicates the presence of a snap ring fitted in the groove, facilitating secure axial location.
- Q66: Specifies a specific radial internal clearance group (CN standard in this case).
- HT51: Represents a specific cage design and material, in this instance, a chrome steel pressed cage, optimized for strength and speed.
6206-ZNRQ66 HT51 Bearing Structural Features & Performance Benefits
The design of the 6206-ZNRQ66 HT51 translates into distinct performance benefits:
- Simplified Assembly and High Rigidity: The integrated snap ring eliminates the need for complex housing shoulders, ensuring precise axial positioning and contributing to a stiffer overall assembly.
- Robust Load Capacity: Constructed entirely from chrome steel, including the rings, balls, and cage, this bearing delivers a high dynamic load rating of 4384 lbf, ensuring longevity under significant radial loads.
- Optimized Speed Performance: The combination of the shielded design and the robust chrome steel cage (HT51) allows for a high limiting speed of 11,000 rpm, making it suitable for high-speed applications.
- Contamination Protection: The shield effectively protects the bearing's interior from larger contaminants, extending service life without the added friction of contact seals.
6206-ZNRQ66 HT51 Bearing Typical Application Areas
This versatile bearing is ideally suited for applications requiring reliable radial load support and simplified mounting. Common uses include:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery where a snap ring location is specified.
