Analysis of Four Common Materials of Deep Groove Bearings

- Jun 21, 2021 -

What is deep groove ball bearing
Deep groove ball bearings, formerly known as single-row centripetal ball bearings, are the most widely used rolling bearings. It is characterized by small friction resistance, fast speed, can be used to bear radial load or radial and axial simultaneous action on the mechanical combined load, can also be used to bear axial load.

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.

Analysis of Four Common Materials of Deep Groove Bearings

Analysis of four common materials of deep groove bearings
The common materials of deep groove balls are the following four:
1. Rings and ball materials: rings and ball are usually made of high carbon chromium bearing steel. Most deep groove ball bearings use SUJ2 steel in JIS steel, that is, domestic chrome steel (GCr15). The chemical composition of SUJ2 has been used as the standardized bearing material in the world. For example, it belongs to the same steel class as AISL52100 (USA), DIN100CR6 (West Germany), and BS535A99 (UK). In addition to the above kinds of steel, according to the specific use of different, will also use high speed steel with excellent heat resistance and stainless steel with good corrosion resistance as the bearing production materials.
2. Cage material: the stamping cage material is made of low carbon steel. Depending on the application, brass and stainless steel plates can also be used. Iron cages are made of high strength brass, carbon steel, and also synthetic resins.
3, dust cover and sealing ring: dust cover to carbon steel as the standard, if necessary, can also choose AISI-300 stainless steel. Different types of sealing materials can be used to achieve high temperature operation and compatibility with grease. Fluorocarbons, silicones, and PTFE seals are usually used at high temperatures.
4. Lubricant: standard grease is injected into bearings with dust caps and seals. Different lubricants can be used according to actual requirements. Standard lubricants are used for open deep groove ball bearings.
