ZEN 686 2RS Ball Bearing 6x13x5 mm – sealed miniature bearing

Main Description

The ZEN 686 2RS 6x13x5 mm is a precision miniature deep groove ball bearing designed for applications requiring compact dimensions, quiet operation, and effective contamination protection. Thanks to its double sided 2RS sealing design, this bearing provides long operational life and stable performance in devices operating at high rotational speeds.

The ZEN 686 2RS bearing is equipped with rubber seals on both sides that effectively reduce the ingress of dust, moisture, and contaminants into the bearing interior. This construction also helps retain lubricant inside the raceways, extending component lifespan and reducing maintenance requirements.

The 6x13x5 mm dimensions make this bearing suitable for small electric motors, electronic devices, model engineering, industrial automation, and precision rotating systems. Miniature ball bearings from the 686 series are commonly used in lightweight industrial mechanisms and compact devices with limited installation space.

ZEN is a respected bearing manufacturer supplying solutions for industrial, technical, and precision applications.
