The MR106-ZZ is a precision-engineered single-row miniature ball bearing designed for high-velocity applications where low rotational torque is a priority. Featuring dual-side metal shields (ZZ), this ultra-slim 6×10×3 mm component offers an effective defense against dust and dry contaminants without the friction drag associated with rubber contact seals. The non-contact metal shields ensure that the factory-applied grease remains contained within the raceways, allowing for exceptionally smooth, high-RPM performance in clean or semi-protected mechanical environments.
