The "686ZZ/2RS" bearing is a miniature deep groove ball bearing with specific characteristics. Here's a detailed overview:

Size: The dimensions of the 686ZZ/2RS bearing are typically specified as follows:

Inner Diameter (ID): [Specific measurement] (e.g., 6mm)

Outer Diameter (OD): [Specific measurement] (e.g., 13mm)

Width: [Specific measurement] (e.g., 5mm)

These dimensions provide a clear indication of the physical size of the bearing, crucial for fitting it into various applications.

Noise Level: The noise level of a bearing is often indicated by an industry-standard rating such as the ABEC (Annular Bearing Engineers' Committee) scale. The ABEC scale ranges from ABEC-1 (lowest precision, higher noise tolerance) to ABEC-9 (highest precision, lower noise tolerance). However, it's important to note that ABEC ratings primarily reflect manufacturing tolerances and might not directly correlate with noise levels in all real-world applications. Manufacturers may also use their own noise rating systems.

In summary, the 686ZZ/2RS bearing is characterized by its specific dimensions, making it suitable for applications with limited space requirements. The noise level is determined by industry standards or the manufacturer's own rating system, ensuring performance in diverse operational environments. For precise technical details, it is recommended to refer to the manufacturer's specifications for the specific bearing model in question.

686 bearing has open, seals and shield types, and v-groove inner ring is available.

It widely used in precision instruments, micro motor, remote control model, etc industries.
