UB-3801-B3 - BEARING MEASURE (12 x 21 x 8 mm) -- COD. ( 3801-2RS (double row) - 12 21 8 - 12218 - 12x21x8 )

Key featuresDouble row ball design for combined radial and axial load supportSealed on both sides for protection against contaminantsCompact design with reduced overall dimensionsHigh rotational stabilityStandard internal clearance for smooth operation DescriptionDouble row angular contact ball bearing with dimensions 12 x 21 x 8 mm, designed to support combined radial and axial loads. The double row configuration provides higher load capacity compared to single row bearings while maintaining a compact structure. Seals on both sides help retain lubrication and protect the bearing from dust and contaminants, ensuring consistent and reliable operation over time. SpecificationsType: angular contact ball bearingConfiguration: double rowInner diameter: 12 mmOuter diameter: 21 mmWidth: 8 mmSeals: 2RS rubber seals on both sidesInternal clearance: standardCage: polymer materialEquivalent codes: 3801-2RS, 12218, 12x21x8
