This is a double row angular contact ball bearing with a bore of 12.0 mm, outside diameter of 28.0 mm, and width of 12.0 mm. Net mass is 0.033 kg, and the limiting speed reaches 15800 1/min. The bearing is fitted with seals on both sides and uses a plastic cage, designation TVH, which reduces friction and mass compared to a metal cage. The C3 internal clearance class provides increased radial play, compensating for thermal expansion during operation. The double row design allows this angular contact ball bearing to carry combined loads, both radial and axial, acting in both directions simultaneously due to the paired row arrangement. The integrated seals protect the raceway and rolling elements from contamination and retain the internal grease fill, making relubrication unnecessary under normal operating conditions. The C3 clearance combined with the plastic cage supports stable operation at the specified limiting speed while maintaining smooth rotation across the stated bore and outside diameter range.
