This deep groove ball bearing carries radial and moderate axial loads on a single row of balls, with a bore of 20.0 mm, outside diameter of 52.0 mm and width of 15.0 mm at a net mass of 0.148 kg. It is built as Generation C design with a steel sheet metal cage (JN) and seals on both sides (2HRS), which keep grease inside and contaminants out without extra external protection. Radial internal clearance is C3, wider than standard, and the limiting speed is rated at 14000 1/min. The C3 clearance compensates for temperature rise and fit-related preload, making the bearing suitable where shafts run warm or fits are tighter than nominal. Integrated seals allow grease-filled operation without a separate sealing arrangement, simplifying housing design and reducing maintenance needs. The steel cage supports the stated speed limit and keeps ball guidance stable under the specified load and clearance conditions.
