Deep groove ball bearings are widely used bearing types

The rolling bearing manufacturer tells you about the four major functions of rolling bearings: 1. The inner ring usually fits tightly with the shaft and rotates with it. 2. The outer ring is usually matched with the bearing seat hole or the housing of Machine element for support. 3. The rolling element is evenly distributed between the inner and outer rings with the help of a cage, and its column shape, size, and quantity directly determine the bearing capacity. 4. The cage evenly separates the rolling element and guides it to move on the correct track.

Deep groove ball bearings are a widely used type of bearing with a wide range of applications. This bearing has the characteristics of low friction, low noise, and low vibration, and can achieve high rotational speed. Compared to other types of bearings, they can withstand radial and axial loads in both directions, are easy to install, and require less maintenance. The SKF bearing catalog lists a series of deep groove ball bearing designs, variants, and dimensions.

In addition to the products listed in the catalog, SKF Explorer deep groove ball bearings are custom bearings that provide advantages for applications with special performance requirements. The NNF type bearing is a double row fully loaded cylindrical roller bearing. The bearing consists of an outer ring with a middle retaining edge and two inner rings with double retaining edges. The roller is guided by the inner ring edge guard, and the two inner rings are fixed with snap rings.

This structure not only bears large radial and axial loads, but also can withstand overturning torque, so it is commonly used as a fixed end bearing. In better conditions, NF bearings with seals do not require maintenance and can be exposed to water vapor or polluted environments for a long time. During medium to high speed operation, the bearing can supplement the lubricating oil groove and lubricating oil hole on the outer ring.
