KET FR1810 / FR1810ZZS Miniature Flanged Ball Bearing (5/16" x 1/2" x 5/32") | Precision Industrial Wholesale

Product Description:

Precision Axial Positioning for Compact Engineering Optimize your manufacturing assembly with the KET FR1810 Miniature Inch Flange Bearing. Engineered and tested by Ningbo Kexiang Bearing Technology Co., Ltd., this specialized bearing features an integrated solid outer-ring flange. This design allows for perfect axial positioning by enabling a direct press-fit into straight-bored housings, completely eliminating the need for expensive and complex machined shoulders.

Available in both the open configuration (FR1810) for oil-lubricated environments and the double-shielded configuration (FR1810ZZS) for maximum protection against industrial contaminants.

Key Engineering Advantages:

• Cost-Effective Assembly: The flanged outer ring drastically reduces housing machining costs and simplifies the mounting process in tight spaces.

• High-Speed Stability: Manufactured with rigorous quality control, the FR1810 achieves an impressive limiting speed of 40,000 RPM with grease lubrication and up to 48,000 RPM with oil lubrication.

• Reliable Load Capacity: Delivering a basic dynamic load rating of 540 N and a static load rating of 276 N, ensuring durability in demanding micro-mechanical applications.

• Global Quality Standards: Produced in a facility equipped with automatic noise testing and high-precision roundness instruments to guarantee vibration-free rotation.
