The difference between rolling bearing and sliding bearing

Different structures, slide bearings rely on a smooth surface to support the rotating shaft, which is a part of the contact surface; rolling bearing is rotated by the rolling elements to support the rotating shaft, and the contact portion is a point, the more rolling elements, the point of contact more. Different sport, the rolling bearing is a rolling movement; movement is sliding bearings sliding friction and thus form also completely different. Bearing smooth, reliable, no noise. Bearing in liquid lubrication conditions, the sliding surfaces are separated from lubricating oil without direct contact, but also can greatly reduce the friction losses and wear surface, the film also has a certain vibration absorption ability. But the starting frictional resistance is large. Bearing part of the shaft is called the journal, and the journal mating parts called bush. In order to improve the friction properties of the surface of the pad on the inner surface of the casting antifriction material layer is called the bearing bush. Bearings and bearing liner materials collectively known as the sliding bearing material. Bearing in low-speed applications are generally heavy working conditions, maintenance or filling oil and difficult operation site. Rolling generally consists of an outer ring, inner ring, rolling elements and a cage. Including the role of the inner ring is fitted with the shaft and rotates with the shaft and the bearing outer ring is fitted effect, play a supportive role, by means of rolling element cage rolling elements evenly distributed between the inner and outer rings its shape and size and the number of direct impact on the performance and life of rolling bearings, rolling element cage to make uniform, to prevent rolling off the body to guide the rolling elements rotate lubricant. Rolling easy maintenance, reliable, good starting performance, at moderate speed higher load carrying capacity. Rolling larger radial dimension, poor damping capacity, high speed, low life, sound bigger.
