Type Of Deep Groove Ball Bearings

What is Deep Groove Ball Bearings

Deep groove ball bearing, formerly known as single-row centripetal ball bearing, is the most widely used rolling bearing. It is characterized by small friction resistance, high speed, can be used to bear radial load or radial and axial combined load at the same time on the machinery, can also be used to bear axial load on the machinery, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machinery, tools and so on.

Characteristics of Deep Groove Ball Bearings

Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. Mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has the performance of a certain angular contact ball bearing, and can bear radial and axial combined load. When the speed is high and the thrust ball bearing is not suitable, it can also be used to bear pure axial load. Compared with other types of bearings with the same specification and size as deep groove ball bearings, this kind of bearings has small friction coefficient and high limit speed. But not impact resistance, not suitable for heavy load.

Application of Deep Groove Ball Bearings

Deep groove ball bearings can be used in gearboxes, instruments and meters, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, engineering machinery, roller type roller skates, yo-yo, etc.

Type of deep groove ball bearings

1. Deep groove ball bearings with dustproof cover: standard deep groove ball bearings with dustproof cover, with Z type and 2Z type (NSK called ZZ type) two kinds. Generally used in separate lubrication is more difficult, the placement of lubricating oil road and the inspection of lubrication is not convenient conditions, usually into the bearing internal injection of rust prevention, lubrication dual lithium grease is one quarter to one third of the internal space of the bearing.

2.Deep groove ball bearings with sealing ring: standard deep groove ball bearings with sealing ring have contact sealing ring bearings RS type (NSK DDU type, sealed on one side) and 2RS type (sealed on both sides) and non-contact sealing bearings RZ type (NSK VV type, sealed on one side) and 2RZ type. The performance, grease filling, use and bearing with dust cover are basically the same, the difference is that there is a large gap between the dust cover and the inner ring, and the gap between the sealing lip and the inner ring of the non-contact sealing ring is small, there is no gap between the sealing lip and the inner ring of the contact sealing ring bearing, the sealing effect is good, but the friction coefficient has increased.

3. Deep groove ball bearings with stop grooves and with stop ring: the rear code of standard deep groove ball bearings with stop grooves is N, and the rear code of deep groove ball bearings with stop grooves and with stop ring is HR. In addition, there are Zn, ZnR and other structural variants. In addition to the function of bearing radial load, the deep groove ball bearing with stop ring can limit the axial displacement of the bearing, simplify the structure of the bearing pedestal and reduce the bearing size. Generally used in cars, tractors and other axial load is not large working parts.
