【 Jiaxing bearing sales center 】 Bearing seal originally there is so much knowledge

There is rotational, have HRB bearing ( ) 【 Jiaxing bearing sales center 】 Bearing seal originally there is so much knowledge. Jiaxing bearing group sales co. , LTD. ( The company) Is jiaxing bearing factory set up in the spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong cash supply ability. Keep good lubrication condition in order to make the bearings and normal working environment, give full play to the performance of the bearing, prolong service life, the rolling bearing must have appropriate sealing, in order to prevent the leakage of lubricants and the invasion of the dust, moisture or other contaminants. Bearing seal can be divided into two categories, own seal and seal. The so-called bearing with seal is made bearing itself into a sealing device. Such as bearing with dust cover, sealing ring, etc. This seal take up the space is small, easy installation and disassembly, cost is low. Alleged bearing and sealing device, it is inside the installation end cover manufacturing into a sealing device has a variety of performance. The choice of bearing and seal should consider the following several major factors: 1. The bearing lubricant and types ( Grease and oil) ； 2. The size of the bearing work environment, take up the space; 3. Shaft supporting structure advantages, allowing the angular deviation; 4. The circumference of the sealing surface speed; 5. The working temperature of bearing; 6. The manufacturing cost. Plus seal is divided into non-contact and contact. Points above are as follows: 1 is non-contact sealing non-contact sealing seal and its relative motion parts don't contact, and there is proper clearance seal. This form of seal, almost do not produce friction heat in the work, no wear and tear, especially suitable for high speed and high temperature occasion. Commonly used non-contact seal clearance, all kinds of different structure forms, such as type labyrinth and washer respectively applied in different situations. Non-contact seal clearance is better to as small as possible. 2 contact seal contact seal is sealed with relative motion of the parts in contact and no seal clearance. Due to seal the seal, direct contact with mating parts in the work of friction is bigger, calorific value is big, easy cause poor lubrication, contact friction losses, resulting in the sealing effect and performance degradation. Therefore, it is only applicable to medium and low speed working conditions. Contact seal commonly used have felt seal, cup sealing structure, applied to different occasions. According to the bearing working condition and working environment requirement for sealing on the engineering design is often integrated use of various seal form, in order to achieve better sealing effect. 24-hour customer service hotline: if you are more interested in jiaxing bearing the author introduced the industry information or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - Editor: jiaxing bearing factory HRB bearing sourcing consultant LTD.
