2Z (Shielded)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.

Shield Advantages • non-contacting with inner ring will not affect torque. • Prevents large particles from entering bearing. • improves lubrication retention in bearing. Shield Disadvantages • Does not provide positive sealing against fine contamination. Sealed bearings would have an advantage here.
