Two differences in the use of bolted roller bearings and deep groove ball bearings, how to choose suitable bearings

The full complement bearing.com/cylindrical-roller-bearings.html' target='_blank'>cylindrical roller bearing dynamic body is a cylindrical roller radial rolling bearing. The internal structure of the cylindrical roller bearing adopts the rollers arranged at 90° perpendicular to each other (this is also the origin of the name of the crossed roller bearing). The rollers are equipped with distance retainers or spacers, which can avoid the inclination of the rollers or the rollers. Grinding each other effectively avoids the increase of rotational torque. The full complement cylindrical roller bearing is a common type of rolling bearing. Basic deep groove ball bearings consist of an outer ring, an inner ring, a set of steel balls and a set of cages. There are two types of deep groove ball bearings: single-row and double-row. The structure of deep groove balls is divided into two types: sealed and open. The open type means that the bearing does not have a sealed structure. The sealed deep groove ball is divided into dust-proof seal and oil-proof. seal. The same points of full complement cylindrical roller bearing and deep groove ball bearing: mainly accept radial load, and can accept small local axial load. The difference between cylindrical roller bearings and deep groove ball bearings: 1. The operating limit of deep groove ball bearings is high, the axial load capacity is relatively large, and the radial load capacity is relatively small; 2. The use limit of cylindrical roller bearings The rotational speed is not as high as that of deep groove ball bearings, which cannot accept axial loads at all, but the ability to accept radial loads is relatively large. The basis for the selection of cylindrical roller bearings and deep groove ball bearings: Cylindrical roller bearings are preferred under low speed and heavy load conditions, and deep groove ball bearings are preferred under high speed and light load conditions. For details on the limit speed and rated load of the bearing, please refer to the mechanical design manual or consult the manufacturer.
