6205-2RSHTN9/C4GJN Bearing Product Overview & Core Advantages
The 6205-2RSHTN9/C4GJN is a sealed single row deep groove ball bearing engineered for high-performance industrial applications. This metric bearing is characterized by its ability to handle significant radial loads while offering reliable operation across a wide temperature range. Its key advantages include robust construction with Chrome Steel components, a lightweight Nylon cage for smooth high-speed operation, and integrated sealing for enhanced service life. Designed with a C4 radial internal clearance, it is well-suited for applications requiring accommodation for thermal expansion.
6205-2RSHTN9/C4GJN Bearing Model Code Explained, Specifications & Naming Convention
- 6205: Basic series designation; 25 mm bore, 52 mm OD, 15 mm width.
- 2RS: Bearing is fitted with contact seals on both sides for effective contamination exclusion.
- H: Typically indicates a set of dimensional or material enhancements.
- TN9: Signifies a glass fiber reinforced polyamide (Nylon) cage, promoting low friction and high-speed capability.
- C4: Denotes a greater than normal radial internal clearance, ideal for applications with significant thermal gradients.
- GJN: Specifies the type of high-performance polyurea grease used for lubrication.
6205-2RSHTN9/C4GJN Bearing Structural Features & Performance Benefits
This bearing's design delivers distinct performance advantages. The single row deep groove geometry is optimized for high radial load capacity, with a dynamic rating of 3147 lbf. The Nylon (TN9) cage reduces centrifugal forces, enabling a high limiting speed of 13,000 rpm and ensuring smooth, quiet operation. The double-contact seals (2RS) effectively retain the factory-applied GJN grease and exclude contaminants, resulting in a maintenance-free and long service life. The C4 clearance provides operational stability in applications prone to thermal expansion, preventing premature failure due to excessive preload.
6205-2RSHTN9/C4GJN Bearing Typical Application Areas
The 6205-2RSHTN9/C4GJN is a versatile component found in a wide array of demanding sectors. Its combination of speed, sealing, and load capacity makes it ideal for:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment (conveyors, fans)
- Agricultural Machinery
- Automotive Components (alternators, idler pulleys)
