INA bearing lubrication systems increase friction methods

1.INA bearing lubrication will bring tangential friction.

Common bearing lubrication in the raceway basically will be fully filled, bearing operation is only a small part of the lubricant will form a lubricating film, most of the lubricant will be rolling body squeezed to the edge of the raceway. When the invalid lubricant back to the bottom of the raceway, and the rolling body will form a certain tangential friction between.

2.INA bearing lubrication system backfill poor oil.

INA bearing lubrication system backfill poor oil, will also increase the bearing friction coefficient. When the bearing speed is too fast or lubricant viscosity is too high, rolling body pressure over the raceway most of the lubricant will be squeezed out, to not urgent backfill to contact with the bearing rolling body parts. At this time, the bearing will appear poor oil operation, friction will increase accordingly. Bearing backfill poor oil phenomenon often appears in oil and gas lubrication, oil spray lubrication, low oil level oil bath and grease lubrication situation.

Submerging bearings in lubricating oil.

In NTN bearing oil bath lubrication, the bearing is partially submerged, or in some special cases, the bearing is completely submerged. In these cases, the size, geometry and oil level of the reservoir will have a substantial effect on the friction torque of the bearing.
