This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, with a solid laminated fabric cage (TB) guiding the rolling elements. Bore diameter is 50.0 mm, outside diameter 80.0 mm, width 16.0 mm, and net mass 0.28 kg. Limiting speed reaches 12200 1/min, with a reference speed of 8900 1/min, giving the bearing a solid margin for higher rotational speeds within its size class. Radial internal clearance is set to C3 (Group 3), which is wider than standard clearance and compensates for thermal expansion or interference fits during operation, keeping the bearing free from excessive preload. The fabric cage construction supports smooth ball guidance at elevated speeds and reduces friction compared to stamped steel cages. As an open bearing without integrated seals or shields, it requires external sealing and a separate lubrication supply suited to the application's speed and load conditions.
