KET FR168 Inch Flange Bearing (6.350 x 9.525 x 3.175 mm) | High-Precision Miniature Bearing for Industrial & Motor Applications

Source premium KET FR168 and FR168ZZS miniature flange bearings. High-speed, durable, and fully certified. Ideal for precision instruments, micro-motors, and robotics. Reliable B2B supply chain solutions for Europe and Eurasia.

Product Overview: The KET FR168 Inch Flange Bearing is engineered for high-performance, low-friction operation in demanding precision environments. Manufactured by Ningbo Kexiang Bearing Technology Co., Ltd., this miniature bearing provides superior radial support while integrating a built-in flange for exact axial positioning and simplified housing installation.

Whether you are assembling advanced robotics, medical imaging equipment, or high-speed micro-motors, the FR168 ensures optimal rotational efficiency and longevity. Supported by international quality management systems (ISO9001, IATF16949) and comprehensive SGS testing, this bearing is the trusted choice for OEM manufacturers and industrial distributors across the European and Eurasian supply chains.

Key Features:

• Premium Material Quality: Manufactured from high-grade bearing steel for maximum durability and wear resistance. Fully compliant with RoHS and SVHC standards, ensuring seamless integration into strict global markets.

• High-Speed Capability: Engineered for low-noise and rapid rotation, operating smoothly at limiting speeds up to 48,000 RPM with grease lubrication and 56,000 RPM with oil lubrication.

• Integrated Flange Design: The flanged outer ring securely locks the bearing in place against axial thrust loads, eliminating the need for separate retaining rings and reducing assembly time.

• Versatile Shielding Options: Available in both Open (FR168) and Shielded (FR168ZZS) configurations to protect internal rolling elements from industrial dust and contaminants.
