Why do 6200 series deep groove ball bearings provide low friction operation?

The raceway groove of the 6200 series deep groove ball bearing is designed to be both deep and wide. This geometric shape allows the rolling elements to roll stably and smoothly in the raceway, reducing additional friction caused by rolling element runout or deflection. 6200 series bearings are usually designed as radial bearings with a contact angle close to 0 degrees. The contact area between the rolling elements and the raceway groove is maximized and distributed more evenly, thereby reducing the pressure per unit area and reducing friction and wear.
Bearing steel has high hardness, high toughness, good fatigue resistance and corrosion resistance. These characteristics enable the rolling elements and inner and outer rings to maintain smooth surfaces for a long time and reduce friction. In specific applications, ceramics (such as silicon nitride) are used as rolling element materials. Because of their extremely low friction coefficient, high hardness and excellent wear resistance, they can significantly reduce friction and wear while improving the operating efficiency of the bearing. and longevity.
Select the appropriate grease or oil according to the application conditions. These lubricants not only have the appropriate viscosity, but also contain anti-wear and antioxidant additives, which can effectively reduce friction, prevent corrosion, and take away the heat generated by friction. In some complex systems, an automatic lubrication system may be equipped to ensure that the bearings continue to receive an appropriate amount of lubricant and maintain a low friction state.
The inner and outer rings, rolling elements and cages of the bearings are precision machined to ensure extremely high dimensional and geometric accuracy, reducing assembly errors and unnecessary friction during operation. Through heat treatment processes such as quenching and tempering, the hardness and toughness of the material are improved while maintaining the uniformity of the internal structure, helping to reduce friction and wear.
Seals made of rubber, polytetrafluoroethylene (PTFE) or other low-friction materials can not only effectively prevent external contaminants from entering the bearing, but also reduce friction between the seal and the bearing components. In some high-speed or high-temperature applications, a non-contact seal design may be used to isolate external contaminants through a tiny air gap or oil film, further reducing friction and wear.
