6304-2Z Bearing Product Overview & Core Advantages
The 6304-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This precision bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its compact design, featuring integral shields (2Z) and pre-lubrication, ensures high reliability and long service life with minimal maintenance. Manufactured to P6 tolerance class, it guarantees superior running accuracy, making it an ideal choice for applications requiring high rotational precision and consistent operation.
6304-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6304 | Standard bearing series designation indicating a metric bearing with a 20mm bore, 52mm OD, and 15mm width. | Defines the core bearing dimensions for interchangeability and selection. |
| 2Z | Signifies the bearing is equipped with non-contact steel shields on both sides. | Provides effective protection against contamination while allowing for high-speed operation with minimal friction increase. |
6304-2Z Bearing Structural Features & Performance Benefits
- Optimized Internal Geometry & High-Grade Materials: The deep groove raceway and high-precision chrome steel components (rings and balls) work in unison to provide smooth operation and a high dynamic load rating of 3777 lbf, ensuring durability under demanding conditions.
- Superior Contamination Protection: The stainless steel cage offers excellent corrosion resistance and strength. Combined with the 2Z shields, the bearing is effectively sealed against dust and other particulates, significantly extending its service life.
- Precision & High-Speed Capability: Manufactured to P6 tolerance class, this bearing ensures minimal runout and vibration. The optimized design and grease lubrication contribute to a high limiting speed of 15,000 rpm, making it suitable for high-speed applications.
- Reduced Maintenance & Ready-to-Install: The bearing is pre-lubricated with grease and sealed, creating a maintenance-free unit that is clean and ready for immediate installation, reducing downtime and total cost of ownership.
