Cylindrical roller bearings and deep groove ball bearings
Mainly bear radial load, can withstand a small number of axial load.
Cylindrical roller bearings and deep groove ball bearings different points:
1, deep groove ball bearings Use a higher limit speed, axial load bearing capacity is relatively large, radial load bearing capacity is relatively small;
2, cylindrical roller bearings using the ultimate speed without deep groove ball bearings, basic can not withstand axial load, but the radial load bearing capacity is relatively large.
The basis of selection of cylindrical roller bearing and deep groove ball bearing:
In the case of low speed and heavy load, the optimum cylindrical roller bearing is preferred and the deep groove ball bearing is optimized under high speed. Specific bearing limit speed and rated load to consult the mechanical Design manual or to the manufacturer.
"Cylindrical roller bearings"
The movable body is a radial rolling bearing of cylindrical rollers. The inner structure of cylindrical roller bearing adopts roller to 90° and vertically cross arrangement (which is also the name of the cross roller bearing), the roller is equipped with spacer cage or isolation block, which can prevent the roller from the tilt or roller between the rollers, effectively preventing the increase of rotation torque.
"Deep groove ball Bearings"
Deep groove ball bearings are the most common type of rolling bearings. The basic type deep groove ball bearings consist of an outer ring, an inner ring, a set of steel balls and a set of cages. Deep groove ball bearing types are single row and double row two kinds, deep groove ball structure is also divided into sealed and open two types of structure, open means bearing without sealing structure, sealed deep groove ball is divided into dust-proof seal and oil seal.
