2RS (Sealed)Miniature Bearings

Some applications may not allow the use of open bearings. Shields or seals may be used to protect against contamination and help retain lubricant.


Seal Advantages • Contact with inner ring prevents small and large particulate from entering bearing. • Greatly improves lubricant retention in bearing. • Acts as a pressure or flow barrier. Seal Disadvantages • increases bearing torque. • Limits bearing speed due to inner ring contact. Shielded bearings would have an advantage here.
