SET2520 ZZ Bearing Product Overview & Core Advantages
The SET2520 ZZ is a metric single row deep groove ball bearing engineered for precision and reliability in compact applications. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include the ability to handle radial loads efficiently and its shielded (ZZ) design, which helps retain lubrication and exclude contaminants, contributing to a long service life in demanding environments.
SET2520 ZZ Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| SET | Indicates a specific bearing series with a 20mm bore and 25mm outside diameter. |
| ZZ | Signifies that the bearing is equipped with non-contact steel shields on both sides. This provides effective protection against contamination while allowing for high-speed operation. |
SET2520 ZZ Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 20x25x4 mm and a weight of just 3.3g, this bearing is ideal for applications with severe space and weight constraints.
- High Precision: Manufactured to ABEC-1 tolerance class, ensuring consistent performance and smooth operation.
- Robust Load Capacity: The deep groove raceway and single-row design are optimized to handle significant radial dynamic loads (204 lbf) and radial static loads (140 lbf).
- High-Speed Capability: The combination of stainless steel construction and ZZ shields enables a limiting speed of 7,600 rpm, making it suitable for high-speed spindles and miniature motors.
- Wide Temperature Range: Operates reliably across a broad temperature spectrum from -86 to 230 °F (-66 to 110 °C).
