Structure and Classification of Deep Groove Ball Bearings

Structure:

Deep groove ball bearings have a simple structure and are easy to achieve higher manufacturing accuracy than other types, so they are convenient for mass production in series, the manufacturing cost is low, and they are extremely common. In addition to the basic type, deep groove ball bearings have various modified structures, such as: deep groove ball bearings with steel shields, deep groove ball bearings with rubber seals, deep groove ball bearings with retaining grooves Deep groove ball bearing with ball notch and large load capacity, double row deep groove ball bearing.

Type:

Deep groove ball bearings are mainly used to support radial loads, but they are also commonly used to support combined radial and axial loads. In particular, when the speed of mechanical equipment is very high, it is not suitable to use thrust bearings. This bearing can be used to bear bidirectional pure axial load, and it requires no maintenance during work. It is a low-priced and widely used bearing. Deep groove ball bearing models are: deep groove ball bearing (type 6000); deep groove ball bearing with outer groove (6000N type); deep groove ball with shield on one side and retaining groove on the other side Bearing (6000-ZN type); deep groove ball bearing (6000-2ZN type) with shield on both sides and retaining groove on the outer ring; deep groove ball bearing (6000Z type) with shield on one side; both sides Deep groove ball bearing with shield (6000-2Z type); deep groove ball bearing with seal on one side (6000-LS type, 6000-RZ type); deep groove ball bearing with seal on both side s (6000- 2LS type, 6000-2RZ type); flanged deep groove ball bearing (F6000 type); flanged deep groove ball bearing with shield on one side (F6000-Z type); There are 11 types of flange deep groove ball bearings (F6000-2Z type).

According to the size of deep groove ball bearings, they can be divided into:

(1) Miniature bearings ---- bearings with a nominal outer diameter range of 26 mm or less;

(2) Small bearings ---- bearings with a nominal outer diameter range of 28-55mm;

(3) Small and medium ---- sized bearings-bearings with a nominal outer diameter range of 60-115mm;

(4) Medium and large bearings ---- bearings with a nominal outer diameter range of 120-190mm

(5) Large sized bearings ---- bearings with a nominal outer diameter range of 200-430mm;

(6) Extra large bearings ---- bearings with a nominal outer diameter range of 440mm or more.
