6901-2RS Sealed Ultra-Thin Deep Groove Ball Bearing for Compact & Lightweight Applications | 12×24×6 Mm

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.



6901-2RS Deep Groove Ball Bearing 12×24×6 mm | Extra Thin Series | Double Rubber Sealed

Built on a space-saving deep groove design, this sealed bearing supports smooth and quiet operation at speeds up to 22,000 r/min (Oil). Capable of handling light to moderate radial loads, the 6901-2RS offers an effective sealing solution for compact assemblies in environments where both contamination protection and minimal cross-section are essential.
