6302-2Z/C3VT376 Bearing Product Overview & Core Advantages
The 6302-2Z/C3 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This shielded bearing excels at handling primarily radial loads and offers a robust solution where space is limited. Its key advantages include a C3 radial internal clearance, which accommodates thermal expansion in high-speed or high-temperature environments, and integral shields that protect against contamination. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides a dependable balance of precision and value for a wide range of industrial uses.
6302-2Z/C3VT376 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6302 | Standard bearing series designation indicating a metric, single row deep groove ball bearing with a 15mm bore, 42mm OD, and 13mm width. | Defines the core bearing dimensions and type for interchangeability. |
| 2Z | Denotes a bearing with shields on both sides. | Provides effective contamination protection, retaining lubrication and extending service life. |
| C3 | Specifies a radial internal clearance greater than the Normal (CN) group. | Prevents binding in applications with thermal expansion, such as in electric motors. |
6302-2Z/C3VT376 Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured entirely from chrome steel for rings, balls, and cage, ensuring high strength, durability, and resistance to wear.
- Optimized Load Capacity: The deep groove raceway geometry enables it to handle significant radial dynamic load ratings (2563 lbf) and radial static load ratings (1225 lbf).
- High-Speed Capability: With a limiting speed of 17,000 rpm, it is suitable for high-speed applications like small motors and spindles.
- Pre-Protected Design: The non-contact shields (2Z) effectively seal the bearing from dust and debris without significantly increasing friction, making it a maintenance-free solution in many environments.
- Thermal Resilience: The C3 internal clearance is a critical feature for applications where operational heat causes shaft and housing expansion, preventing premature failure.
6302-2Z/C3VT376 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors: Ideal for small to medium-sized motors due to its speed capability and C3 clearance.
- Gearboxes and Power Transmission Systems: Handles radial loads in compact drive assemblies.
- Pumps and Compressors: Provides reliable performance in fluid handling equipment.
- Material Handling Equipment: Used in conveyor rollers, pulleys, and fans.
- Agricultural Machinery: Suitable for various components requiring a shielded, durable bearing.
