6302-ZTN9/C3VM036 Bearing Product Overview & Core Advantages
The 6302-ZTN9/C3VM036 is a single row deep groove ball bearing engineered for high-performance applications requiring reliable radial load capacity and precision operation. This metric bearing features a shielded design and is manufactured to ABEC 1 | ISO P0 tolerance class, ensuring consistent quality and smooth running. Its optimized internal geometry, combined with a C3 radial internal clearance, makes it suitable for applications with potential thermal expansion or where a slightly looser fit is desired. The bearing is designed for a broad temperature range of -30°C to 120°C, offering versatility across various operating environments.
6302-ZTN9/C3VM036 Bearing Model Code Explained, Specifications & Naming Convention
- 6302: Basic model number indicating a single row deep groove ball bearing with a 15mm bore, 42mm OD, and 13mm width.
- Z: Signifies that the bearing is equipped with a shield on one side, protecting the internal components from large contaminants while minimizing friction.
- TN9: Denotes the cage (retainer) material. The "TN9" specifically indicates a glass fiber reinforced polyamide (Nylon) cage. This cage design is lightweight, promotes smooth operation at high speeds, and is compatible with a wide range of lubricants.
- C3: Specifies the radial internal clearance group. A C3 clearance is greater than the standard (CN) clearance, making it suitable for applications where interference fits, shaft heating, or specific thermal conditions are present.
- VM036: This suffix indicates the specific lubrication used. "VM036" refers to a high-quality, pre-applied grease formulation designed for extended service life and reliable performance across the specified temperature range.
6302-ZTN9/C3VM036 Bearing Structural Features & Performance Benefits
The performance of the 6302-ZTN9/C3VM036 is a direct result of its carefully selected components and construction:
- High-Quality Materials: Both the rings and balls are manufactured from Chrome Steel, providing excellent hardness, wear resistance, and durability under load.
- Optimized Cage Design: The Nylon (TN9) cage ensures quiet and smooth operation, even at the bearing's limiting speed of 17,000 rpm. Its lightweight nature reduces centrifugal forces, contributing to high-speed capability.
- Robust Load Capacity: With a dynamic load rating of 2563 lbf and a static load rating of 1225 lbf, this bearing is built to handle significant radial loads in demanding applications.
- Pre-Applied Lubrication: The factory-applied VM036 grease provides immediate and long-lasting lubrication, simplifying installation and promoting a long service life with minimal maintenance.
- Shielded Protection: The Z-shield effectively protects the bearing interior from coarse contaminants, enhancing reliability without the added friction of contact seals.
