10 things need to know when using bearing
10 things need to know when using bearing: When using bearing users encounter some problems such as: How to select bearings, How to choose the suitable grease for bearing/ Is it nescessary to add grease for 2-cap bearing? How to correctly fit it? The everage life expectancy of bearing?How to know symptoms of broken bearing? What methods to know the working status of bearing? How to measure the bearing erosion ? Why using staper beaing which is fitted on the sleeve make it broken quickier? Some recommened remedies.What should be done when the inner ring or outer rings rotates on the sharft.To answer these questions, please read the following article:![]()
1. How to select the bearingSee the method of bearing selection here 2. How to choose the suitable grease?Refering to manufacture's manual to choose the suitable grease (See how to choose grease for SKF bearing here) 3. Is it necessary to add grease for 2 cap bearing?The bearing has available 2 steel cap (-2Z) or two rubber seals (-2RSH or -2RS1) have been pre-lubricated with a suitable type and amount of grease to ensure that these bearings operate to the end of expected life of the bearing. 4. How to correctly bearing?Contact to supplier so that you can fit them corectly or you can watch this video: See steps to install and disassamble bearing here
How to remove the roller bearing here 5. The average of life expectancy of bearingBearing life in various applications is different.Technically, bearing life is determined by rotations, changes depending on: load capacity, working temperature, environment ( dust, moisture, chemicals..) By periodically monitoring the parameters and mentioned descriptions , users can evaluate and predict the operating status of bearings 7. Method to know working status of bearing in usingMentioned in section 6, bearing status is reflected through pramaters such as : temperature, noise, vibration. Periodically monitoring these will help users evaluate bearing status. Curently, the best effective way to monitor and predict the failurre of bearing is measuring and analizing vibration of bearing. Note: Beside you can refer to diagnose of bearing failure 8. How to measure the bearing erosion.Every bearing has standardized slit. Measuring, checking requires specilized equipments with high accuracy. The "lead pressing" method applied in somewhere is recommended not to use because of inaccuracy. Normally, after long time using, the erosion on the surface of rolling gloove is not the same. The peel on the rolling gloove is the main reason causing the failure of bearing if the lubrication will not well-guaranted. Evaluation by feelingdo not allow users to undervest correctly bearing status. 9. Why using staper beaing which is fitted on the sleeve make it broken quickier?Repairing staper bearing is often quickier broken causing due to tightening the screw, the bearing has not enough required inner gap. There is the remaining inner gap after proper mounting. 10. What should be done when the inner ring or outer rings rotates on the sharftThe cause of this phenomenon is due to: |
