SFR166 ZZ RICH 4,762x9,525x3,175

SFR166ZZ RICH Stainless Steel Flanged Miniature Ball Bearing – 4.762 x 9.525 x 3.175 mm

The SFR166ZZ RICH is a high-quality stainless steel flanged miniature deep groove ball bearing, precisely manufactured by RICH in China. It is engineered for applications where corrosion resistance, ultra-compact dimensions, and reliable low-friction performance are critical. With dimensions of 4.762 mm bore, 9.525 mm outer diameter, and 3.175 mm width, it offers an efficient and space-saving solution for micro-precision applications.

Constructed entirely from stainless steel, the SFR166ZZ provides excellent resistance to rust and corrosive agents—ideal for use in medical devices, food processing machinery, small robotics, and other environments where cleanliness and durability are essential. The integrated outer ring flange (D1: 10.719 mm) simplifies axial positioning, ensuring secure and accurate housing fitment. It features a sturdy steel cage for consistent ball guidance and a CN (normal) internal clearance, suitable for standard operating conditions.

This bearing is protected by double metal shields (ZZ) on both sides, effectively sealing the interior against dust and debris while retaining lubricant. Weighing only 0.002 kg, it is extremely lightweight, making it ideal for miniature assemblies where space and precision are key.
