1: ntn bearing interference problems:This requires a stable oil pressure or tension or pressure can exert a tool with the outer shell with D by H8/h7; to extend its life plays an important role, the ball shall be no crushing and pitting; outside The outer corner edge of blade contact with the workpiece. Or pressure lubrication can not meet the cooling requirements of the occasion. So after the accident, can be used to process copper, graphite,

1. By working to identify the temperatureThis method is more recognition method is limited to use in running condition is not change the situation. To this end, the temperature must be continuously recorded. Fails, the temperature not only increased, but also irregular changes. This method is suitable voice recognition method and use.2. Through the identification of the state of lubricantSampling and analysis of the lubricant,

1: ntn bearing inner ring fixed:First, ntn lock nut bearings, ntn bearing inner ring and the locking nut from the shaft shoulder to achieve axial fixation. And have washers with anti-loose, safe and reliable, suitable for high-speed, heavy load situations. Second, ntn bearing a fixed withdrawal sleeves, withdrawal sleeves and adapter clamping sets the same way. However, because of withdrawal sleeves special nut, ntn bearing loading and unloading easy,

General Bearing Appearance characteristics:Roller diameter and length of rolling are small. Cage with roller or inner guidance. Cylindrical roller bearing cage structure with rivets, easy to loose, off cover. Aligning bearing diameter hole without bunkers, poor lubrication.Material:Inside and outside the ring and rolling the ordinary bearing steel. Of zinc brass cage materials, low strength, poor flexibility.

1: ntn bearing cleaning focus:1, cleaning the surface of the object stateSmooth surfaces and rough uneven surfaces cleaned the same way, the effect achieved is very different. In the choice of cleaning method should fully take into account the surface conditions.2, the situation of dirtDirt to be used for different a different cleaning agent for metal surface with oil-based dirt and to scale, oxide-based dirt the selected cleaning agent

1, ntn bearing requirements for the workOne of imports bearing loadBearing loads suffered import size, direction and nature of the choice based primarily on imported bearing type.The size selection based on load bearing type of imports, because imports of roller bearings between the main component is line contact, should be used to bear a larger load, the deformation after the load is also smaller. The ball bearings are mainly imported point contact,

1, ntn bearing nature of the noise datantn bearing nature of noise is the use of modern processing technology made bearings will occur,NTN Bearing determined the structure of the noise itself.Nature of acoustic noise can be divided into roller, ball impact and jarring sound of three kinds of sound, are as follows:(1) ntn roller bearings roller sound and control noise when running NTN Bearing imports,

1, ntn bearing installation program(1), cleaning bearings NTN bearings and related department(2) to check the size of related components and finishing conditions(3), the installation(4), installed after the inspection NTN Bearings(5), the supply of lubricantIn the forthcoming pre-installation, it would only open the NTN bearings imported packaging. General grease lubrication, not clean, direct filling grease. Oil lubrication,
