GCR15 bearing roller are separable bearings, which are very convenient to install and disassemble. GCR15 bearing roller can withstand large radial loads and are suitable for use in high-speed running situations. This type of bearing allows the angular error (inclination) between the axis of the inner ring and the axis of the outer ring to be very small, only 2'～4'. Therefore, the machining accuracy of the shaft and the bearing seat is relatively high. Otherwise, uneven load or stress concentration is likely to occur in the contact part of the raceway.
However, after correcting the roller or raceway contact bus bar, the occurrence of stress concentration can be reduced. GCR15 bearing roller can be divided into single-row, double-row and multi-row GCR15 bearing roller according to the number of rows of rolling elements. Bearings of different structures are also shown in the design of the position of the ribs. In order to ensure a good running condition of the bearing, the single row roller bearing, like other ball bearings and GCR15 bearing roller, must be applied with a certain amount of small load, especially for high speed, high acceleration, or frequent changes in the load direction. jobs.
Because of these working conditions, the inertial force of the roller and the cage and the friction in the lubricant will adversely affect the rolling and rotation accuracy of the bearing, and there may be harmful sliding between the roller and the raceway. sports. In the case of starting at low temperature or high lubricant viscosity, a larger and smaller load may be required. Under normal circumstances, the weight of the bearing support itself plus the load borne by the bearing has exceeded the required small load. If the small load has not been reached, additional radial loads must be applied to this type of bearing to meet the requirements of the small load.
