Determine the the SKF bearings use the degree of damage can be used a second touch, the method of the three observation to determine.
1, listen: the use of a hearing to identify irregular operation is a very commonly use d method. With a screwdriver or electronic stethoscope to detect the approach of a streamlined non-normal noise is experienced operator and maintenance personnel often use. Gimbal bearing good running state will issue a low whining sound, such as bearings issued a sharp hissing sound, squeak, and other irregular sounds, there is a bearing in adverse running state. crossed roller bearing
Touch: high temperatures the SKF bearings often expressed in an abnormal situation, the high temperature of the lubricant within the bearing is harmful, but bearing some when the high temperature caused by the lubricant within the bearing, gimbal bearing more than 120 ℃ temperature will reduce the long-term operation of the bearing life. The reason of bearing high temperature caused by a lack of lubricant or excessive lubrication, lubricant impurities, the load is too large, bearing damage, lack of clearance and the oil seal friction engage. In normal circumstances, the bearing temperature rise just lubrication or after in the lubricating natural and will last one to two days.
Observe: SKF bearing good lubrication and debris and moisture from entering the SKF bearing oil seal wear, if the the original bearing box is opened, shall be visually check the gimbal bearing and regularly check the oil seal. Check status near the bearing at the oil seal to ensure that they are sufficient to prevent hot liquids, corrosive liquids and gas infiltration along the axis of the bearing oil seal if damaged should be replaced as soon as possible. Check the automatic lubrication system to ensure that the oil or grease into the bearing, and ensure that the correct amount of add check lubricant is discolored or black, if this situation usually indicates a lubricant containing impurities, this case bearing is harmful.
