Flanged Ball Bearings With Extended Inner Ring

What Are Flanged Ball Bearings With Extended Inner Ring?

Flanged ball bearings with an extended inner ring are a specialized variation of standard flanged bearings. The inner ring extends beyond the outer race, providing additional shaft support and better alignment during assembly. This design feature minimizes misalignment and axial movement, especially in high-speed or vibration-prone environments.

Key Benefits

• Enhanced Alignment: The extended inner ring ensures better shaft centering, reducing the risk of wobble or misalignment.
• Improved Rigidity: Additional contact with the shaft enhances the bearing’s structural integrity under load.
• Ease of Installation: The flange and extended ring serve as natural mounting and positioning references, reducing setup time.
• Low Maintenance: Ideal for use in enclosed or low-access environments where long-term reliability is critical.

Bore Diameter Range

These bearings come in a compact range suitable for small-scale and miniature equipment:

• Minimum Bore Diameter: 0.04688 inches
• Maximum Bore Diameter: 0.3125 inches

Common Applications

Due to their compact size and precision features, flanged ball bearings with extended inner rings are commonly used in:

• Electric motors and small generators
• Office and printing equipment
• Miniature robotics and automation systems
• Medical devices and diagnostic machines
• Vibration-sensitive assemblies

Why Choose This Type of Bearing?

If your application requires higher stability, better shaft support, and a simple yet effective mounting solution, flanged ball bearings with extended inner rings are an excellent choice. They combine compact design with high performance, making them especially suitable for precision industries.
