The 618/7-ZZ RICH is a miniature single row deep groove ball bearing, designed for high-precision applications where space constraints and protection from contaminants are critical. With compact dimensions of 7 x 14 x 3.5 mm, it's ideal for environments requiring smooth rotation and low-friction performance.
Its ZZ metal shields provide double-sided protection, effectively keeping out dust and debris without increasing drag. The steel cage maintains ball spacing and alignment, ensuring stable, durable operation. With a standard CN clearance, this bearing delivers consistent results across a wide range of general conditions.
Made by RICH in China, the 618/7-ZZ is commonly used in medical devices, RC models, miniature motors, dental tools, and other precision instruments requiring radial load support in tight spaces.
