7202 BE-2RZP Bearing Product Overview & Core Advantages
The 7202 BE-2RZP is a single row angular contact ball bearing designed for high-precision applications requiring superior performance under combined loads. Engineered with P6 (ABEC-3) precision tolerance, this bearing excels in applications demanding high rotational accuracy and rigidity. Its key advantage lies in its ability to efficiently support combined radial and axial loads in one direction, making it an ideal component for compact, high-speed assemblies. The sealed construction and pre-lubrication ensure long-term reliability and reduced maintenance needs.
7202 BE-2RZP Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| BE | Enhanced internal design with optimized contact angle and ball complement for higher load capacity |
| 2RZ | Non-contact rubber seals on both sides providing excellent protection against contamination while maintaining high-speed capability |
| P | Precision grade designation indicating P6 tolerance class (equivalent to ABEC-3) |
7202 BE-2RZP Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The 40° contact angle and optimized internal geometry enable superior resistance to axial loads while maintaining excellent radial load capacity. The distance from side face to load point (16mm) ensures stable moment load support.
Precision Performance: Manufactured to P6 tolerance class with precise dimensional control (bore tolerance: -0.007mm to 0), this bearing delivers consistent high-precision operation essential for precision machinery applications.
High-Speed Capability: The nylon cage provides reduced friction and weight, contributing to the limiting speed of 20,000 rpm. Combined with the non-contact seals, this design maintains optimal performance at high rotational speeds.
Maintenance-Free Operation: The 2RZ rubber seals effectively protect against contaminants while the pre-lubrication ensures consistent performance across the temperature range of -30° to 110°C, eliminating the need for relubrication in most applications.
