Double row angular contact ball bearings are basically two single row angular contact ball

Double row angular contact ball bearings are basically two single row angular contact ball. Bearing installed back to back, in addition to their only an inner ring and outer ring, each one. In the race. They can carry axial load in any direction. Double row angular contact ball bearing four-point contact ball bearing inner ring and outer ring is the inner ring can be separated. Split into radial plane. They can withstand the axial load from any direction. The ball has contact each lap 35 & deg; Angle. Only this type of bearing can replace the combination of face to face. Or back to back angular contact bearings. Commonly used processing brass cage. Double row angular contact ball bearings are basically two single row angular contact ball: a four-point contact ball bearing of the bearing inner ring with two race and the outer ring has a ball the curvature center and the centre axis bearing raceway. As a result, the shaft of inner ring and ball and cage can nearby have a certain amount of deflection in the center of the bearing. Therefore, by processing or installation error caused by the axis and shell of tiny Angle deviation is automatic correction. This type of bearings tend to have a tapered hole installation using the adapter socket. Since the ball bearings in this type of bearings, cylindrical roller and raceway contact is linear. They have a high radial load capacity, suitable for high speed. There are different types of specified nu, NJ, N, NF single bearing, double row bearings and NNU, NN depends on design or no side ribs. All types of outer ring and inner ring are separable. Some of the cylindrical roller bearing without inner ring or outer ring ribs, so the ring can be. The relative axial movement. These can be used as a free end bearing. Cylindrical roller bearing inner ring or outer ring with two ribs, another has a ring. In a single direction absorb a certain amount of axial load. Double row cylindrical roller bearings with high radial stiffness, it is mainly used for precision machine tools. Pressure steel or processing brass cage is usually used, but sometimes molding is also used.
