Product Overview and Core Advantages
The 7204 BE-2RZP is a high-performance single row angular contact ball bearing designed for precision applications requiring superior rigidity and reliability. Engineered to accommodate combined radial and axial loads simultaneously, this bearing features a 40° contact angle for optimal thrust capacity. Its sealed construction with pre-applied lubrication ensures long-term performance with minimal maintenance, making it ideal for demanding industrial environments where precision and durability are paramount.
7204 BE-2RZP Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 7204 | Standard metric size designation (20mm bore, 47mm OD) | Industry-standard dimensions for easy integration |
| BE | Enhanced internal design with 40° contact angle | Optimized for high axial load capacity |
| 2RZ | Non-contact rubber seals on both sides | Effective contamination protection with low friction |
| P | P6 tolerance class (ABEC-3 precision) | High running accuracy for precision applications |
Structural Features and Performance Benefits
Precision Engineering: Manufactured to P6 tolerance class (equivalent to ABEC-3), this bearing ensures exceptional running accuracy and minimal vibration for smooth operation in precision machinery.
High Load Capacity: The 40° contact angle design provides superior axial load carrying capacity while maintaining excellent radial load performance. With dynamic load rating of 2992 lbf and static load rating of 1721 lbf, it delivers reliable performance under demanding conditions.
Advanced Sealing System: The 2RZ non-contact rubber seals effectively prevent contamination ingress while minimizing friction, contributing to the high limiting speed of 14,000 rpm.
Optimized Material Selection: Constructed from chrome steel rings and balls with nylon cage, this combination provides excellent strength, wear resistance, and smooth operation across the temperature range of -30° to 110°C.
