Material of rolling bearings

Rolling material:
Materials bearing member used, has a great influence on the rolling bearing sliding bearing performance and reliability. Usually the bearing rings and rolling elements for consideration include: the carrying capacity related to hardness, fatigue resistance under rolling contact and cleanliness of the different lubrication conditions, as well as dimensional stability. For Cage, to consider friction, strain and inertia forces, but also consider the role of chemical and certain lubricants, solvents, coolants and refrigerants in some cases. The importance of these considerations with respect to the composite bearings also affected other operating parameters. Such as corrosion, high temperature, shock loads or a combination of these factors.

Embedded in the rolling bearing contact seals, but also have a significant impact on the performance and reliability of the bearing. Its manufacturing material used must have excellent resistance to oxidation and thermal or chemical resistance properties.

SKF can provide the use of different materials bearing rings, rolling elements, cage and seals to meet a variety of application needs. In addition, SKF can also provide specially coated bearings, used in or unable to obtain sufficient lubrication work must be prevented by the current.
