The 63802-2RS is a specialized thin-section deep groove ball bearing engineered for applications where radial space is strictly limited but prolonged durability is required. Distinguishing itself from the standard 6802 series, this model features an extended 7 mm width, allowing for an increased internal grease capacity. Equipped with twin nitrile rubber contact seals (2RS), it forms a formidable barrier against moisture ingress and fine dust, making it an exceptional mechanical component for compact motors, cycling components, and precision robotics.
