NTN Original 6004 Z High Precision High Speed Bearing 6004 Z Deep Groove Ball Bearing

The fault phenomenon of NTN bearing is generally manifested as two kinds, one is that the temperature of the bearing installation part is too high, and the other is that there is noise in the operation of the bearing. Several forms of damage: Metal spalling on raceway surface NTN bearing burns Plastic deformation NTN bearing seat ring crack The cage is shattered The metal of the cage adheres to the body Seat raceway is severely worn

Matters needing attention for the use of bearings are as follows: (1). Keep bearings and their surroundings clean. Even the eyes can not see the small dust, will also bring impact to the bearing. Therefore, to keep the surrounding clean, so that dust does not invade the bearing. 2. Use with caution and caution. In the use of bearing strong impact, will produce scars and indentation, become the cause of accidents. In severe cases, cracks and fractures may occur, so attention must be paid. (3). Use appropriate tools. Instead of replacing existing tools, use appropriate tools. Such as *** sleeve, press, etc. (4). Attention should be paid to the rust of bearings. When operating bearings, sweat on the hands can be a cause of rust. Be careful to use clean hands, *** try to wear gloves. (5). Do not unpack the bearing before the installation preparation is completed to avoid pollution.

The fault phenomenon of deep groove ball bearings is generally manifested as two kinds, one is that the temperature of the bearing installation part is too high, the other is that there is noise in the operation of the bearing.

The lubrication purpose of NTN imported bearings is to reduce internal friction and wear of bearings, prevent burning and sticking, and its lubrication effect is as follows: (1) Reduce friction and wear In the ring of the bearing, the rolling body and the mutual contact part of the retainer, prevent metal contact, reduce friction, wear. (2) Extend the fatigue life The rolling body fatigue life of NTN imported bearings is prolonged when the rolling contact surface is well lubricated during rotation. On the contrary, low oil viscosity, lubricating film thickness is not good, it is shortened. (3) Eliminate friction heat and cooling The circulating oil feeding method can discharge the heat caused by friction, or the heat from the outside, and cool down. Prevent overheating of bearings and aging of lubricating oil. (4) Others It also has the effect of preventing foreign bodies from invading the inside of the bearing, or preventing rust and corrosion
