6809 Bearing Product Overview & Core Advantages
The 6809 metric ball bearing is a single row deep groove ball bearing engineered for reliable performance in a wide range of industrial applications. Characterized by its open design and precision ABEC-1 tolerance class, this bearing is optimized for handling significant radial loads. Its compact cross-section, with a 7 mm width, makes it an ideal solution for space-constrained assemblies requiring high operational reliability and consistent performance.
6809 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6809 provides key dimensional information, while the bearing's specifications define its performance characteristics. The following details are inherent to its standard, open design:
- Seal Type: Open - Allows for versatile lubrication options and is suitable for clean environments or where specific lubrication regimes are applied.
- Tolerance Class: ABEC-1 - Denotes a standard level of precision for runout and dimensional accuracy.
- Radial Internal Clearance: C0 - Specifies a normal operating clearance range (0.006mm to 0.023mm) for general applications.
- Cage Material: Stainless Steel - Provides excellent durability and corrosion resistance for the cage component.
6809 Bearing Structural Features & Performance Benefits
The performance of the 6809 bearing is a direct result of its robust construction and material selection.
- High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 1397 lbf and a static load rating of 1210 lbf, ensuring longevity under demanding radial load conditions.
- Optimized for Speed: With a limiting speed of 13,000 rpm, it is capable of high-speed operation, supported by a lightweight, durable stainless steel cage that minimizes friction and maintains stability.
- Precision Engineering: The ABEC-1 tolerance class and controlled internal clearance (C0) guarantee smooth and precise rotation, reducing vibration and noise.
- Broad Operating Range: A temperature range of -30°C to 110°C allows for reliable performance in diverse environmental conditions.
