This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, with a bore diameter of 140.0 mm, outside diameter of 210.0 mm, and width of 33.0 mm. The bearing uses a solid brass cage (M) and weighs 4.07 kg. Limiting speed is rated at 5500.0 1/min, with a reference speed of 4050.0 1/min, giving it stable performance at higher rotational speeds. The radial internal clearance falls in group C4, wider than standard clearance, which compensates for thermal expansion and interference fits under load. The solid brass cage supports reliable ball guidance and stability at the given speed range. These features make the bearing suitable for applications requiring increased clearance to accommodate temperature rise or tight-fit mounting conditions, while maintaining smooth rotation under radial load.
