This angular contact ball bearing transmits combined radial and axial loads through its double row ball arrangement, with contact angle construction providing guidance in two directions simultaneously. Bore diameter is 12.0 mm, outside diameter 28.0 mm, and width 12.0 mm, giving the envelope dimensions for housing and shaft fit. Mass netto is 0.034 kg. The bearing uses a TVH cage, made of plastic, which guides the ball complement and reduces friction between rolling elements. Shields on both sides retain the internal grease fill and limit ingress of coarse contaminants, though they do not provide a full rubbing seal. Limiting speed is 22000 1/min and reference speed 19300 1/min, values to check against the actual operating speed and cooling conditions during shaft design. The double row design with shields and a plastic cage suits installations where axial positioning in both directions is required from a single bearing position, with grease lubrication retained internally rather than relying on external oil feed. The TVH cage construction allows the stated speed ratings to be reached while keeping ball guidance stable at the given bore and outside diameter.
