double row angular contact ball bearings


Double row deep groove ball bearings are very suitable for use in bearing arrangements where the load carrying capacity of single row deep groove ball bearings is insufficient. For double row deep groove ball bearings with the same outer diameter and inner diameter as single row deep groove ball bearings, the width is slightly larger, but the load capacity is much higher than that of the 62 and 63 series single row deep groove ball bearings. Double row deep groove ball bearings are open Style, rubber seal or dust cover.


The design of double row deep groove ball bearings is basically the same as that of single row deep groove ball bearings. The deep groove ball shaft-shaped raceway plus the excellent closeness between the raceway and the steel ball. In addition to bearing radial loads, double row deep groove ball bearings can also bear axial loads acting in two directions.


Standard double row deep groove ball bearings are 4200A, 4300A type. Type A bearings have no ball gaps. Two reinforced nylon cages are inserted from both sides of the bearing. In addition to having a radial load capacity 1.62 times higher than that of single row deep groove ball bearings, double row deep groove ball bearings can also bear axial loads. Standard deep groove ball bearings have ordinary radial internal clearance.

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 borne by the steel ball and cage and shortening the working life of the bearing. Therefore, the allowable angle 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 equipped with two glass fiber reinforced nylon 66 cages. The suffix of EASIER is TN9. Deep groove ball bearings equipped with nylon cages can operate at temperatures up to 120°C.


The characteristics of the cage are not affected by the lubricants used in general rolling bearings, except for certain synthetic oils or greases based on synthetic oils and lubricants containing a large amount of extreme pressure additives for high temperature applications.


Deep groove ball bearings are the most widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.


In order to make the bearings run well. Double row deep groove ball bearings, like all ball bearings and roller bearings, must bear a certain minimum load, especially at high speed or high acceleration, or when the load direction changes rapidly. Under these conditions, the inertial force of the ball and the cage and the friction in the lubricant will have an adverse effect on the rolling of the bearing, and there may be damaging sliding motion between the ball and the raceway.
