1: Angular contact ball bearings:1. Single bearing can tolerate this type of axial load in one direction, also need to configure other bearings to offset the additional axial force, made on the installation of the additional axial force which offset each other, and can afford two Power up the axial load, and has two directions of a strong axial limit capacity, generally installed in pairs using two sets of bearings in its outer end is relatively wide (back to back) or the relatively narrow end (face) two to install forms,

1, screw ntn bearing outer ring can be reused many times, making the event as due to the damage caused by the impact of temperature and bending to its re-processing possible. In this case, bearing also need to be adjusted. Bearing is adjusted by the diameter size of 1 mm increase in the number of the manner of.2, screw ntn bearing durability and are subject to dirt, iron filings, water, and drop the iron and the formation of acidic water has little influence.

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,

Ball bearings in contact with the Contact Characteristics of vibration caused by incentives, thus affecting the access to the Contact Characteristics of factors such as load, speed and bearing lubrication will affect the vibration characteristics.Ball bearings bearing vibration noise is spread in the air by people feeling the results of the auditory system. Some China-made low-noise deep groove ball bearing vibration and noise

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.

Compared with plain bearings, deep groove ball bearings of the excellent Compared with plain bearings, deep groove ball bearings of the inferior 1, the general conditions, the efficiency and fluid dynamic bearing lubrication bearing considerable, but higher than the number of hybrid bearings;  1, less able to withstand impact loading; 2, radial clearance is small, angular contact bearings can be used to preload cardiac
