 SKF Bearing rotation test should be carried out after installation, first used in the axis of rotation or SKF bearings box, without exception, no load will be in power at low speed, and then depending on the functioning gradually increase the rotation speed and load, and to detect noise, vibration and temperature rise, abnormal, should stop running and check. Before running the test is normal delivery. 
 Second, SKF import bearing removal: 
 SKF bearings removed intend to continue to use, you should use the appropriate removal tool. The demolition of the interference fit of the ring, only to increase the tension in the ring, never to allow demolition of the rolling elements, or the rolling element and raceway will be crushed. 
 Three SKF imported bearings using the environment: 
 Select Size, accuracy, according to the location and conditions of use and environmental conditions with the appropriate SKF Bearing is to ensure that the premise of the SKF Bearing life and reliability. 
 1, using the site: tapered roller SKF Bearing bear radial load mainly radial and axial joint load, usually two sets of SKF import bearing paired, primarily in the car's front and rear wheels, active cone transmission parts such as gears, differentials, reducer. 
 2, which allows speed: in a correctly installed, well-oiled environment, allowing for SKF bearings limit the speed of 0.3-0.5 times. Under normal circumstances, the limit of 0.2 times the speed of the most suitable. 
 3, which allows the angle of inclination: tapered roller SKF imported bearings generally do not allow shaft relative shell hole tilt, if tilt does not exceed 2 '. 
 , Allowing the temperature: under normal load, and lubricant high temperature performance, and adequate lubrication conditions, SKF import bearing allows the ambient temperature of -30 ℃ -150 ℃.

 The role and requirements of the three tapered roller bearing clearance 
 Exist in the tapered roller bearing clearance is the flexibility in order to ensure the tapered roller bearing block to operate, but also guarantee tapered roller bearings running smoothly, the axis of the tapered roller bearing no significant settlement, and bear the load the number of rolling bodies as much as possible. 
 Therefore, the dynamic performance of the clearance tapered roller bearings, tapered roller bearings (noise, vibration and friction) and rotation accuracy, the carrying capacity of life (wear and fatigue) has a significant impact. 

 Rust-proof material, surface preparation methods: 

 1) Surface cleaning: cleaning must be according to the nature of the surface to be rust-proof and the conditions, selected the appropriate method. Commonly used solvent cleaning method, chemical processing, cleaning and mechanical cleaning method. 
 2) the surface is dry and clean filter available dry compressed air, or 120 ~ 170 ℃ dryer drying can also be used to clean gauze dry. 
 SKF bearing life of the material factors 
 Early failure of the form of rolling bearings SKF's main rupture, deformation, wear, corrosion and fatigue under normal conditions, the contact fatigue. The failure of the SKF bearing parts in addition to the conditions of service, mainly due to the hardness, strength, toughness, wear resistance, corrosion resistance and stress state constraints. The main internal factors that influence these performance and state the following number. 
 Quenched martensite in steel 
 Retained austenite in quenched steel 
 Quenching of undissolved carbides in the steel 
 Residual stress in quenched and tempered 
 Impurity content of the steel 
 (Guangdong the SKF agents) K850/K832] 
 Obtained in order to make the material factors of the above affect the SKF bearing life at its best, you first need to control the quenching of steel before the original organization, technical measures can be taken are: high temperature (1050 ℃) austenitic-speed cooling to 630 ℃ temperature normalizing fine pearlite, or pseudo-eutectoid cooling to 420 ℃ temperature treatment, to obtain bainite. Unwrought waste heat can be used to rapid thermal annealing, the fine granular pearlite to ensure that small and evenly distributed carbide steel. The original organization of this state in the quenching of austenitizing, in addition to integration into the carbide in austenite, undissolved carbides, will gather into a fine granular.
