Product description
The 685ZZMC3E PS2S NSK is a miniature ball bearing. This is a very small single-row deep groove ball bearing. The design consists of an inner and an outer ring, with a ball and cage assembly in between. Thanks to their simple construction, these bearings require little maintenance. With their compact dimensions, miniature bearings are suitable for applications where space is limited. Additionally, miniature ball bearings boast significant radial load-bearing capacity. They can handle light axial loads as well, offering versatility across a wide range of applications.
The cage of the 685ZZMC3E PS2S NSK ensures that the balls do not touch each other and move in a controlled manner. This generates less heat and enables high speeds. The low friction and quiet operation make them ideal for high-speed and noise-sensitive environments like consumer electronics. Their durability, combined with efficient heat dissipation, ensures long-lasting performance with minimal maintenance, reducing the need for frequent replacements. Miniature ball bearings are widely used in situations where very high rotational rates are required.
