Double row ball bearing4303ZZ/2RS/OPEN

The design of double row deep groove ball bearings is basically the same as single row deep groove ball bearings. The deep groove ball-shaped raceway and the raceway and the steel ball have excellent adhesion. In addition to radial loads, double row deep groove ball bearings can also withstand axial loads acting in two directions.

Standard double row deep groove ball bearings are 4200A, 4300A type. A-type bearings have no balap. Two reinforced nylon cages are inserted from both sides of the bearing. Double row deep groove ball bearings have a radial load capacity 1.62 times higher than single row deep groove ball bearings, and can also withstand axial loads.

Double row deep groove ball bearings are suitable for bearing arrangements 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 the single row deep groove ball bearings in the 62 and 63 series.

The standard deep groove ball bearing is the radial internal clearance of the ordinary group.

Cage

Double row deep groove ball bearings are equped with two gla fiber reinforced nylon 66 cages. The suffix is TN9.

Deep groove ball bearings fitted with nylon cages can operate at temperatures up to 120 ° C.

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

Minimum load

In order to get the bearings running well. Double row deep groove ball bearings, like all ball bearings and roller bearings, must withstand a certain minimum load, especially at high speeds or high accelerations, or when the load direction changes rapidly. Under these conditions, the inertial force of the ball and cage and the friction in the will have an ad effect on the rolling of the bearing. Between the ball and the raceway, there may be a sliding motion that damages the bearing.

Precautions for use

When starting at a low temperature or when the viscosity of the grease is high, a larger minimum load may be required. The weight of the bearing, plus external force, usually exceeds the required minimum load. If the minimum load has not yet been reached, the bearing must be subjected to an additional radial load.
