The 6901-2RS is a Double Rubber-Sealed Ultra-Thin Section Deep Groove Ball Bearing designed for space-sensitive applications requiring reliable sealing and low-profile design. Equipped with two rubber contact seals (2RS), it effectively shields against dust, moisture, and contaminants while retaining grease for extended service. Featuring a 12 mm bore and an exceptionally slim 6 mm width, this bearing is ideal for small motors, precision instruments, and compact mechanisms where axial space is limited.
