Today, the engineer from -AOBOTE BEARING(fagbearing-china) would teach you the information about the difference between the sliding bearing and rolling bearing. May be we know many famous bearing brand such as the SKF bearing, FAG bearing, NSK bearing and INA bearing. But you should not know the difference among the different bearing type.

Sliding bearing which means that the bearings would operate under the sliding friction. The operation of the sliding bearing is smooth, reliable and no noise. In liquid lubrication conditions, the surface of the sliding bearing is separated by the lubricating oil without direct contact. This would greatly reduce the friction loss and surface wear and tear. On the other hand, the oil film also has a certain vibration absorbing capability. But the starting frictional resistance of the sliding bearing such as the Timken bearing is very huge.

In order to improve the frictional properties of the surface of the pad, we should add the casting surface which is known as the FAG ball bearings bush. The material of the pad and the bearing bush are collectively referred to the sliding bearing material. The general sliding bearing materials are bearing alloy, cast iron, copper Sleeve Bushing Manufacturers and aluminum-based alloy, powder metallurgy materials, plastics, rubber, hardwood, polytetrafluoroethylene(PTFE) and modified polyoxymethylene (POM). The applications of sliding bearing such as the NTN bearing are generally in the low speed and heavy working conditions. On the other hand, the sliding bearing would also be applied in the area where are difficult in maintaining and filling oil.

The bearing which could change the sliding friction of precision mechanical components into rolling friction between the operation of the shaft and the shaft holder, thereby reducing the friction loss, called the rolling bearing. Rolling bearings are generally consisted by the outer ring, inner ring, rolling elements and cage. The role of the inner ring is aligned with the axis and together with the shaft rotating. The function of the outer ring is compatible with the bearing base. It is play a supportive role. The distribution of rolling elements in the inner and outer rings is by means of cage uniform. The shape and quantity of the rolling element would directly affect the performance and life of rolling bearings. The retainer enables the evenly distributed of the rolling elements.

The FAG roller bearings have the advantages of easy maintenance, reliable operation, good starting performance and higher carrying capacity at moderate speed. Compared with the sliding bearing, the radial size of rolling bearing is larger but poor damping capacity. When the operation is at high-speed, the rolling bearing would have the shortcomings of low life and huge sound. The movement of these two kinds of bearing is in different ways. The motion of rolling bearing is a rolling and the sliding bearing is the sliding movement.
