The working conditions of INA roller bearings are harsh, and whether their working performance can be effectively played depends largely on the lubrication of the bearings.
INA roller bearings grease lubrication grease and sealing role, sealing structure and lubrication facilities are simple, easy to replenish grease, so as long as the working conditions allow, bearings are generally used grease lubrication. Oil lubrication cooling effect is strong, and can take away dirt and moisture from the INA imported precision roller bearings. iko bearings using oil lubrication lubrication methods are pressure supply lubrication, oil spray lubrication, oil mist lubrication and oil and gas lubrication.
Lubrication has an important influence on the fatigue life and friction, wear, temperature rise and vibration of rolling bearings. Without normal lubrication, the bearings cannot work. Analysis of the causes of bearing damage shows that about 40% of bearing damage are related to poor lubrication. Therefore, good lubrication of the bearing is an effective measure to reduce the friction and wear of the bearing.
Pressure oil lubrication is the most effective way to lubricate the bearings under the conventional speed.
Spray lubrication is the dry compressed air containing oil mist sprayed into the internal bearing for lubrication, using less oil, due to the role of air, the cooling effect is extremely strong, mainly used for high rolling speed and rolling high precision large bearings, or for in the bearing box not often disassembled INA imported precision roller bearings.
Pressure supply lubrication and oil injection lubrication are required to install into, out of the oil pipe, lubrication pump, oil reservoir, sometimes also need lubricating oil cooler, so the cost will be relatively high.
1)The noise of ball bearings is lower than that of roller bearings, and the (friction) noise of the relative sliding less German INA imported precision roller bearings is lower than that of the relative sliding more bearings.
2)The noise of using solid cage bearing is relatively lower than that of using pressed cage bearing; the noise of using plastic cage bearing is lower than that of using the above two kinds of cage roller bearing; the number of balls is more, the outer ring is thicker, the noise is also smaller.
3)The noise of high precision bearing, especially the bearing with higher precision of rolling body used, is relatively smaller than the noise of low precision bearing.
4)The noise of small bearings is relatively smaller than the noise of large INA imported precision roller bearings.
