The MR106-2RS is a highly resilient, single-row miniature deep groove ball bearing designed for precision applications where space is limited and environmental protection is paramount. Measuring just 6×10×3 mm, this micro-bearing is equipped with premium dual synthetic rubber contact seals (2RS). This sealing mechanism forms an aggressive barrier against fine dust, particulate matter, and liquid ingress. Unlike standard metal shields, the NBR rubber seals maintain a continuous, light-friction contact with the bearing's inner ring, locking the factory-applied lubricant inside and drastically reducing the need for maintenance in challenging or outdoor environments.
