6304-2Z/HT Bearing Product Overview & Core Advantages
The 6304-2Z is a single row deep groove ball bearing featuring integral shields on both sides. Engineered for radial load applications, this metric bearing is characterized by its high-speed capability and robust construction using chrome steel. Its shielded design offers superior protection against contamination while maintaining low friction, making it a reliable and versatile component for a wide array of industrial machinery. The bearing is supplied without lubrication, allowing for application-specific greasing, and conforms to ABEC 1 | ISO P0 tolerance standards for consistent performance.
Model Code Breakdown
| Prefix/Suffix | Technical Meaning |
|---|---|
| 63 | Series code indicating a medium duty, single row deep groove ball bearing. |
| 04 | Bore diameter code, corresponding to a 20 mm bore. |
| -2Z | Signifies the bearing is shielded on both sides. The shields retain lubricant and protect the internal components from large particulate contaminants. |
6304-2Z/HT Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel (rings, balls, and cage), this bearing delivers high strength and durability. It offers a dynamic load rating of 3574 lbf and a static load rating of 1765 lbf, ensuring reliable operation under significant radial stresses.
- Optimized for High-Speed Operation: The deep groove raceway and precision-ground components contribute to smooth rolling motion, enabling a high limiting speed of 14,000 rpm. This makes it suitable for demanding applications requiring rapid rotation.
- Effective Contamination Protection: The non-contact steel shields (2Z) provide a highly effective barrier against dust and debris without significantly increasing rotational torque, helping to extend bearing service life.
- Standardized Precision: Built to ABEC 1 | ISO P0 tolerance class and standard CN radial internal clearance, this bearing ensures consistent dimensional accuracy and operational reliability for general industrial use.
6304-2Z/HT Bearing Typical Application Areas
