E – bearing side of the loading ball mouth, can be loaded with more steel balls, so has a high radial and axial bearing capacity. Spherical roller bearings CAC, ECAC, CA, ECA – these are designed for large size bearings, the rollers are symmetrical. The inner ring has fixed retaining edges on both sides, and the movable center retaining ring is guided by the inner ring. The cage is an integral brass or steel solid frame. the roller and raceway surfaces of the CAC and ECAC types are optimally machined to aid roller guidance and to reduce friction. the ECAC type comes with reinforced rollers to increase load capacity.
In the daily maintenance and repair of the engine, it is necessary to pay attention to the appearance shape of the alloy surface, back, end and edge angles of the bearing, if there are abnormalities or signs of excessive half wear, we must carefully identify the causes and take appropriate measures to improve the working conditions of the bearing and pay attention to the prevention of early damage to the sliding bearing.
