Сферический роликовый подшипник, внутренний диаметр 200 мм Caterpillar 4660388

A Spherical Roller Bearing features rows of barrel-shaped rollers housed within an inner ring with a spherical raceway and an outer ring with a common spherical raceway. This unique design allows the bearing to accommodate not only radial loads but also axial loads and angular misalignment between the shaft and housing. The rollers are guided by cages to maintain proper spacing and prevent contact with each other.Attributes:• Provided with three equally spaced lube holes of diameter 12mm to keep the roller lubricated• Rollers are arranged with Inner Race Guided Brass Cages to prevent one-to-one contact between themApplications:A Spherical Roller Bearing handles significant loads during excavator and crane operations, ensuring smooth rotation and minimizing wear on the shaft and bearing itself. The working principle of a spherical roller bearing for swing pinion is based on the interaction between the rollers and the races. As the inner race rotates, the rollers roll between the two races, reducing friction and wear.
