Single-row deep groove ball bearings are the most common type of rolling bearings. These shielded (2Z or ZZ) bearings from NSK are fitted with two metal dust shields to prevent the ingress of dirt and foreign matter into the bearing housing. NSK’s range of bearings are available in a variety of metric sizes with varying inside and outside diameters to ensure the perfect fit. Found in a wide range of applications in many industries, NSK’s bearings are ideal for machinery in printing, medical, manufacturing and agricultural as well as applications such as wind turbines for renewable energy collection.

Deep groove ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.

The purpose of a deep groove ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.

A deep groove ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.
