AXK0619TN needle roller bearing

Jiaxing bearing manufacturing co. , LTD. , production of needle roller bearing, needle bearing with fine and long roller ( Roller diameter D 5 mm or less, the L/D 2 or more. 5, L for roller length) , so the radial structure is compact, its inner diameter size and load capacity at the same time, with other types of bearing outside diameter is small, especially suitable for radial size by a limited amount of supporting result. According to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components, at this time to suit the bearing surface of the surface of the shaft and the shell hole directly as inner and outer rolling bearing surface, in order to ensure the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, machining accuracy and surface quality should be as a bearing ring raceway. These bearings can bear radial load only. Product introduction: by plane thrust bearing with thrust needle roller or thrust cylindrical roller cage of components and the thrust washer. Needle roller and cylindrical roller cage to keep and guidance, in conjunction with different types and series of washer, you can configure a number of different combinations. If the adjacent parts surface is suitable for race, could save the gasket. Cylindrical roller thrust bearing with needle or ball thrust cage of components and the thrust washer. Needle roller and cylindrical roller thrust cage to keep and guidance. With different series of DF thrust bearing washer when used together, can provide bearing configuration with many different combinations. Due to choose high precision cylindrical roller ( Needle) Increased the contact length, make the bearings in a small space can be obtained under high load capacity and high stiffness. Another advantage is that, if the adjacent parts surface is suitable for saves a raceway surface of the gasket, can make the design is compact, DF thrust needle roller bearing and cylindrical roller bearing thrust needle roller and cylindrical roller cylinder for the modification of surface, edge can reduce stress, improve the service life. Product advantages and usability: needle bearing with fine and long roller ( For 3 ~ 10 times the diameter of the roller length, diameter, generally no more than 5 mm) , so the radial structure is compact, its inner diameter size and load capacity at the same time, with other types of bearing outside diameter is small, especially suitable for radial installation size limit of the supporting structure. Needle roller bearing according to the use of different occasions, the machining accuracy and surface quality should be combined with bearing ring, use. Needle roller bearing is a centripetal needle bearing and thrust bearing parts of the bearing unit. Product production process and protective measures: the production of needle roller bearing is blank, deburring, heat treatment, thick, thin, end mill rolling surface, super finishing rolling surface or sawdust polishing process. If the needle roller bearing processing in the process of blank, not able to keep the size, so need to increase the double end face grinding process. About the needle bearing on its load and performance in terms of performance, all need testing bearing. Needle roller bearing can be divided into single, two-way operation in different ways, including one-way needle roller bearing is a one direction can be independently rotating, locked in another direction of a bearing. Common is usually applied to textile machinery, automobile industry, printing machinery, household appliances, and other areas of the industry. One-way needle bearing quality will directly affect the normal operation of the machinery and equipment, so it can be said to be one of the important parts of mechanical equipment. If the equipment can keep normal operation for a long time, so first you need to ensure the one-way needle roller bearing is not damaged. Protect the needle roller bearing damaged should first invasion of the pollutants in the dust, in order to reduce the relative motion of the rolling element and raceway less wear and tear; And regularly filling lubricating grease, to ensure its good lubrication effect; You can also use the oil and gas, oil mist or spray lubrication to improve cooling conditions. In addition, it is necessary to further strengthen to improve the purity of the needle roller bearing lubricating oil, can better extends the service life of bearing. Meanwhile keep the purity of the bearing, high cleanliness of bearing vibration velocity is low, wear small, which can increase the service life of bearing.
