Carries combined radial and axial loads through its double row of balls set at a contact angle, providing higher rigidity than a single-row design at comparable size. The 3810-2Z has a bore of 50.0 mm, outside diameter of 65.0 mm and width of 12.0 mm, with a net mass of 0.093 kg. Shields protect the raceway on both sides, and the TVH cage is a plastic (polyamide) design running with the balls. Limiting speed is rated at 8100 1/min, with a reference speed of 5400 1/min. The double-row angular contact arrangement allows this bearing to take axial loads from either direction without needing a paired mounting, making it suitable where axial positioning of the shaft must be maintained in both directions within a compact width. The plastic TVH cage keeps friction and heating low at the stated speeds, while the shields limit ingress of contaminants without adding the drag of full rubbing seals, so relubrication intervals should follow the operating conditions rather than being assumed sealed-for-life.
