Bearings are precision components, be careful when in use. No matter how high-performance spherical bearings, if used improperly, it will not get the expected performance. Here are some of INA bearings precautions for use.
Even if fine dust invisible into the bearing, will increase the bearing wear, vibration and noise. Bearings and their peripheral accessories should be kept clean, especially dust and dirt, tools and working environment must be kept clean.
Direct hands to take bearings, be sure to wash hands sweat, and coated with high-quality mineral oil before, during the rainy season and summer with particular attention to rust. However, in some specific operating conditions, INA bearings can get a longer life of the conventional calculation, especially in the case of light load. These special operating premise is that when the rolling surfaces (track and rolling elements) is an effective lubricant film separating and limiting pollutants may cause surface damage. In fact, under the premise of the ideal, the so-called permanent bearing life is possible.
1 bearing grease too little, too much or iron and other impurities. INA bearing grease capacity should not exceed 70% of the total volume, should be replaced with impurities
3 Bearing and end caps fit too tight or too loose. When machining the bearing chamber tight, too loose when the end cap inserts steel sleeve.
4 motor cover or bearing cap assembly ends bad. Will cover only the mouth or into the bearing cap, installed flat, tighten the screws.
5 the belt tight or low torque coupling assembly out of the interior of the bearing INA axial gap can be moved by means of the axial position of the outer ring to achieve.
