Deep Groove Ball Bearings

The deep groove ball bearing is the most typical one of rolling bearings, which is suitable for high speed applications. It is also very durable and do not ask for frequent maintenance. Compared with other types of bearings with same specifications, the deep groove ball bearing has lower coefficient of friction and higher limit speed. But it also shows intolerance of impact, and cannot bear heavy loads. It is suitable for high-precision instruments, low-noise motors, automobiles, motorcycles, and other common machinery, as the most widely used type of bearings in machinery industry.

Deep groove ball bearing

The deep groove ball bearing mainly take radial load as well as take moderate axial load. The axial load capacity increases with radial clearance. The contact angle is zero when bearing radial force only, and axial force will result in a contact angle larger than zero. This series usually uses ribbon cage and solid cage, and sometimes uses nylon cage.

Mestto owns patent on the solid cage structure (with type codes plus YA8). This kind of cage has advantages on saving labor, energy, and non-ferrous brass. It is economical that it largely saves production costs for customers. It also shows good lubricity.
