This double row angular contact ball bearing carries loads in both radial and axial directions from a single unit, with a bore of 10.0 mm, outside diameter of 30.0 mm, and width of 14.0 mm. Net mass is 0.052 kg, and the limiting speed reaches 16100 1/min. The design uses a TVH cage made of glass-fibre reinforced plastic, together with seals on both sides marked 2RSR that keep grease in and contaminants out. The double row arrangement gives the bearing a defined contact angle on each side, allowing it to take combined loads and to locate a shaft axially in both directions without a mating bearing. The integrated seals allow operation with the initial grease fill and reduce the need for relubrication, while the plastic cage keeps mass low and supports the stated limiting speed.
