This double row angular contact ball bearing carries a 25.0 mm bore, 52.0 mm outside diameter and 20.6 mm width, with a net mass of 0.172 kg. Built on the X-life design, it uses a TVH glass-fibre reinforced polyamide cage and is fitted with 2HRS seals on both sides. The C3 internal clearance and limiting speed of 10700 1/min are the key running parameters for this size. The two-row angular contact arrangement takes combined radial and axial loads from both directions within a single unit, giving stable guidance where axial positioning in both directions is required. The integrated seals keep grease in and contaminants out, so the bearing runs pre-lubricated without needing external relubrication. The C3 clearance compensates for temperature rise in operation, and the TVH cage design supports smooth ball guidance and reduced friction at the stated limiting speed.
