Design features and special characteristics

Deep groove ball bearings are very widely used.

A deep groove is formed on each inner and outer ring of the bearing enabling them

to sustain radial and axial loads in either direction as well as the complex loads

which result from the combination of these forces.

Deep groove ball bearings are suitable for high speed applications.

In addition to unsealed bearings, deep groove ball bearings include ball bearings

with greased sealed inside (sealed or shielded) and bearings with a snap ring

that simplify structure around the bearing and design.

Table 1 shows the construction and special characteristics

of various sealed deep groove ball bearings.

Product Description

Deep groove ball bearing  are the most common type and are used in a wide variety of applications.  Not only are they capable of supporting radial loads but also moderate axial loads in either direction.  Due to their low torque, they are suitable for applications where high speed and low power loss is required. They are easy to mount and suitable for many different configurations.

Deep groove ball bearing  are the most widely used bearing type, especially in electric motors. These non-separable bearings are suitable for high speeds. The deep uninterrupted raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and axial loads in both directions. Bearings with a bore diameter d ≤ 45 mm are most suitable for electric motors in the power range of 0,15 up to 15 kW as well as power tools and high-speed drives. 

Deep Groove ball bearing  are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements.The bearing ring grooves are circular arcs made slightly larger than the radius of the ball.The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders). Deep Groove ball bearings can sustain radial, axial, or composite loads and because of simple design, this bearing type can be produced to provide both high-running accuracy and high-speed operation. Standard ball retainers (cages) are made from pressed steel. Machined cages are used in bearing operation at very high speed or for large diameter bearing.

Deep Groove Ball Bearing Brief Introduction

1. Deep groove ball bearing is one of the most common type of rolling bearings.

 2.General deep groove ball bearing consists of an outer ring, an innner ring,  a group of steel ball and cage.

 3.It has single row and double row  two type.

 4.It is sealed and open two kinds of structure. Open  refers to the bearing without the seal structure and seal type deep groove ball divided into dust seal and oil
