Double row deep groove ball bearing features
Double row deep groove ball bearing features:
Double row deep groove ball bearings are suitable for bearing configurations where the load capacity of a single row deep groove ball bearing is insufficient. For double row deep groove ball bearings with the same outer diameter and inner diameter as deep groove ball bearings, the width is larger and the load capacity is much higher than that of the single row deep groove ball bearings of the 62 and 63 series. Standard deep groove ball bearings are common radial internal clearances.
Centering error: When there is a misalignment between the inner and outer rings of a double row deep groove ball bearing, it will cause additional load. Thereby increasing the load on the steel ball and the cage and shortening the working life of the bearing. Therefore, the allowable angular error is only 2 arc minutes. Any larger angular error will result in an increase in noise.
Cage: Double row deep groove ball bearings are fitted with two glass fiber reinforced nylon 66 cages. SKF suffix is TN9. Deep groove ball bearings with nylon cages can operate at temperatures up to 120 °C.
The characteristics of the cage are not affected by the lubricant used in general rolling bearings, but some synthetic oils or synthetic oil based greases and lubricants containing a large number of extreme pressure additives are excluded for high temperature applications.
Double row deep groove ball bearings are a kind of bearing arrangement, which is very suitable for the case of insufficient load capacity of single row deep groove ball bearings. When there is a misalignment between the inner and outer rings of a double row deep groove ball bearing, an additional load is caused. This phenomenon is called a centering error. With the deepening of the use of double row deep groove ball bearings, the study of double row deep groove ball bearings has attracted a lot of attention. Among them, the characteristics of double row deep groove ball bearings have become the product information that experts and users pay more attention to.
