The characteristics of double groove ball bearing

The design of double groove ball bearing is basically the same as that of single row deep groove ball bearing.Deep groove ball shaft shape raceway plus raceway and steel ball have excellent tightness.In addition to deep groove ball bearing radial load, double row deep groove ball bearing can also bear axial load in both directions.
The characteristics of double groove ball bearing

Deep groove ball bearing is suitable for use in a single row deep groove ball bearing configuration with insufficient load capacity.For double groove ball bearing with the same outer diameter and inner diameter as deep groove ball bearings, their width is larger and their load capacity is much higher than that of series 62 and 63 single row deep groove ball bearings.
Standard deep groove ball bearings for the general radial internal clearance.
To make the bearing run well.double groove ball bearing, like all ball bearings and roller bearings, must bear a certain minimum load, especially at high speed or high acceleration, or in the direction of the load changes rapidly.Under these conditions, the inertia force of the ball and the cage and the friction in the lubricant will have a bad effect on the rolling of the double groove ball bearing, and the sliding movement may be harmful to the bearing between the ball and the raceway.

Notes for folding use
Starting at a low temperature or with a high viscosity of grease may require a greater minimum load, the weight of the double groove ball bearing, plus external forces, usually in excess of the required minimum load.If the minimum load is not reached, the bearing must be subjected to additional radial load.
