KET FR188 & FR188ZZ Inch Flange Bearing (6.350 x 12.700 mm) | Precision Miniature Bearing for Industrial Motors

Source premium KET FR188 open and FR188ZZ shielded miniature flange bearings. Engineered for up to 50,000 RPM. IATF16949 & ISO9001 certified. Ideal for robotics and drones. Reliable B2B supply chain solutions for Europe and Eurasia.

Product Overview: The KET FR188 Inch Flange Bearing series delivers exceptional radial load support and precise axial positioning in a highly compact form factor. Manufactured strictly by Ningbo Kexiang Bearing Technology Co., Ltd., this bearing integrates a solid outer steel flange, which significantly simplifies housing installation and eliminates the need for external retaining rings.

Designed for high-speed, low-friction operations, the FR188 is the optimal choice for precision instruments, micro-motors, and advanced UAV technology. Fully backed by comprehensive quality systems as verified in our qualification documents like "科翔IATF16949证书.webp" and "iso9001.webp", this component meets the rigorous compliance requirements of top-tier OEM manufacturers and industrial distributors across the European and Eurasian supply chains.

Key Features:

• Advanced Flange Integration: The built-in outer ring flange securely locks the bearing against axial thrust loads, streamlining complex assembly processes.

• Extreme Speed Capacity: Achieves a limiting speed of up to 50,000 RPM with oil lubrication and 40,000 RPM with grease lubrication, ensuring completely reliable performance in high-velocity applications.

• Dual Configuration Availability: Select the open FR188 for continuous fluid lubrication environments, or the shielded FR188ZZ for maximum internal protection against industrial dust and contaminants.

• Certified Quality Assurance: Produced by a certified enterprise  with rigorous environmental compliance validated by SGS testing
