6204-2Z Bearing Product Overview & Core Advantages
The 6204-2Z is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This precision bearing features integral shields on both sides, offering reliable protection against contaminants while retaining lubrication. Engineered with a P6 tolerance class, it provides superior running accuracy and is optimized for handling significant radial loads. Its compact design, combined with pre-applied grease, makes it an ideal, ready-to-install solution for applications requiring high reliability and minimal maintenance.
6204-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 6204 | Standard series designation indicating a metric bearing with a 20mm bore, 47mm OD, and 14mm width. | Defines the core bearing dimensions for interchangeability and selection. |
| 2Z | Signifies a shielded bearing with non-contact steel shields on both sides. | Provides effective contaminant exclusion with minimal impact on limiting speed, promoting longer service life. |
6204-2Z Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from chrome steel for rings and balls, and a stainless steel cage, this bearing ensures high durability and corrosion resistance, contributing to a high dynamic load rating of 3035 lbf.
- Optimized for Radial Loads: The single row deep groove geometry is specifically engineered to carry substantial radial loads efficiently, with a static load capacity of 1472 lbf.
- High-Speed Capability: The lightweight stainless steel cage and optimized internal design enable a high limiting speed of 17,000 rpm, suitable for various high-speed applications.
- Maintenance-Free Operation: The combination of Z-type shields and factory-applied grease lubrication creates a sealed, lubricated-for-life unit, ideal for applications where re-lubrication is difficult.
- Precision Performance: Built to a P6 tolerance class with a standard CN radial internal clearance, this bearing offers precise running accuracy and low vibration for smooth operation.
