Double row deep groove ball bearing NSK friction maintenance skills

Double row deep groove ball bearing with NSK bearings is to make the action of stationary ring and rotating ring parts of a static local respectively with device ( Usually bearing) Local (and rotation Usually the shaft, Consolidation in together, so as to complete transmission in the condition of rotating load and limit the basic task of motion systems related to stationary position. NSK bearings on the shaft and bearing seat, the request in the radial, axial and tangential direction to three directions such as fixed position. After the positioning of the radial and tangential double row deep groove ball bearing ring the tight fit of mining is complete, the axial positioning only in a few cases with tight fit; Common USES axial spacing parts, such as end cover and retaining ring could happen on the axial location clearance range. Double row deep groove ball bearing diameter of axle adhesion and avoid direct contact with bearing bush attack form border smooth performance. Affect the friction pair friction compatibility of data elements are: ( 1) As deputy information on metallurgical alloy difficulty levels. ( 2) Data and affinity to smooth agent. ( 3) As a deputy data in the condition of no smooth friction factor. ( 4) The microstructure of materials. ( 5) Thermal conductivity of materials. ( 6) Data can appearance size and characteristics of the oxide film. High pressure oil in the oil pump by the nozzle jet to the bearing, NSK bearings into the bearing at the other end into the oil in the tank. In bearing high speed rotates, and insist on roller frame is around with fairly high rotate speed makes air flow, using ordinary smooth method can smooth the oil to the NSK bearings, when required by high radiation will smooth oil spray to double row deep groove ball bearing, the position of the nozzle should be placed between inner ring and adhere to the center.
