The R4-2RSC3 RICH Single Row Deep Groove Ball Bearing is a high-precision miniature component engineered for applications demanding smooth, efficient rotational motion within confined spaces. With precise dimensions of 6.35 mm inner diameter, 15.875 mm outer diameter, and a 4.978 mm width, this bearing is ideal for intricate mechanisms. Manufactured in China by RICH, it features double-sided rubber contact seals (2RS) for superior protection against contaminants, and a C3 greater than normal internal clearance to accommodate higher speeds, thermal expansion, or misalignment.
The "2RS" sealing ensures that the bearing is well-protected from dust, dirt, and moisture, while also retaining lubricant effectively, leading to extended service life and reduced maintenance. The C3 clearance is particularly beneficial in applications where operating temperatures are high or where slight misalignment might occur, preventing premature wear and ensuring smooth operation.
Weighing just 0.008 kg, this RICH miniature deep groove ball bearing offers a practical and robust solution for optimizing performance and durability in compact electronic devices, medical equipment, small motors, and precision instruments.
