Built for precise, high-speed applications, the RICH 689-2Z is a miniature single row deep groove ball bearing that combines compact size with reliable strength. Manufactured in China under strict quality controls, this bearing offers dependable performance even in space-constrained assemblies. With a 9 mm bore diameter, 17 mm outer diameter, and just 5 mm thickness, it’s ideal for intricate mechanical designs requiring smooth rotation and minimal friction losses.
Dual metal shields (2Z) protect the rolling elements from external contaminants while maintaining lubricant retention for longer service life. The internal steel cage provides precise alignment of the balls, while the typical CN clearance allows for optimal radial load management. Lightweight yet durable, this bearing weighs approximately 0.042 kg and suits applications such as small electric drives, hobby mechanisms, measuring instruments, and professional micro-tools.
