308SZZ-HYB#1 Bearing Product Overview & Core Advantages
The 308SZZ-HYB#1 is a single row deep groove ball bearing engineered for high-performance applications. Its core advantages stem from its ceramic ball (silicon nitride) construction, which provides superior performance in demanding conditions. This bearing is designed to handle primarily radial loads efficiently and is characterized by its high limiting speed and excellent operational characteristics within a wide temperature range. The combination of a shielded design and precision manufacturing to ABEC 1 | ISO P0 tolerance makes it a reliable and durable component for various industrial uses.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 308 | Basic bearing series, indicating a metric bore diameter of 40 mm and standard cross-section. |
| S | Designates the use of Ceramic Balls (Silicon Nitride) for enhanced speed and durability. |
| ZZ | Indicates the bearing is shielded on both sides (2Z). This provides effective protection against contaminants while being a non-contact seal suitable for high-speed operation. |
| HYB#1 | A manufacturer-specific designation, often referring to a particular series, internal specification, or internal radial clearance (CN) group. |
308SZZ-HYB#1 Bearing Structural Features & Performance Benefits
- Ceramic Ball Technology: The use of silicon nitride balls significantly reduces weight and centrifugal force, contributing to a higher limiting speed (8,500 rpm). They also offer superior resistance to wear and thermal expansion.
- Shielded Design: The ZZ shields protect the internal components from dust and other particulates without generating significant friction, making it ideal for clean and high-speed environments.
- High Load Capacity: With a dynamic load rating of 10,274 lbf and a static load rating of 8,093 lbf, this bearing provides reliable performance under significant radial loads.
- Precision Engineering: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard CN radial internal clearance, ensuring consistent and smooth operation.
- Wide Temperature Range: Constructed from chrome steel rings and a steel cage, it operates reliably in temperatures from -30°C to 120°C.
308SZZ-HYB#1 Bearing Typical Application Areas
- High-Speed Spindles in machining centers and routers
- Electric Motors and precision gearboxes
- Medical Equipment such as dental handpieces and centrifuges
- Aerospace Actuation Systems and auxiliary units
- Robotics and automation joint mechanisms
