SL bearings are usually guided by two ribs of a bearing ring, cages, rollers and guide rings to form an assembly, generally separable bearings. This kind of bearing is easy to install and disassemble.

The double row cylindrical roller bearing consists of an inner ring, an outer ring, a roller and a cage. The inner and outer rings are connected together by rollers and cages. The roller is cylindrical, by rolling on the inner and outer rings, to achieve the operation of the bearing. The role of the cage is to maintain the position of the roller so that it can be evenly distributed between the inner and outer rings of the bearing. Double row cylindrical roller bearings are compact in structure and large in carrying capacity, which are suitable for high-speed rotation and high load conditions.

The rolling body is the centripetal rolling bearing of cylindrical roller. The inner structure of cylindrical roller bearing adopts rollers to be arranged in parallel, and there is a spacer or isolation block between rollers, which can prevent the tilt of rollers or friction between rollers, and effectively prevent the increase of rotating torque.  Single row cylindrical roller bearings: Single row cylindrical roller bearings are separable bearings for easy installation and disassembly. Both rings can be fitted tightly. Modified contact lines between rollers and raceways can reduce stress concentration. 

Single row cylindrical roller bearing is usually only subject to radial force, compared with the ball bearing of the same size, the radial bearing capacity is increased by 1.5-3 times, good rigidity, impact resistance, it is especially suitable for rigid support, and support the short shaft, heat elongation caused by axial displacement of the shaft and the installation and disassembly of the machine accessories need separation type bearing.

A single-row tapered bearing is usually adequate for the most straightforward applications (e.g., angular forces on a fixed point and with only mild fluctuation). To find the right one, you'll need to determine whether the end-use of the tapered bearing will have more radial or axial loads. There are axial-only tapered roller bearings called thrust tapered bearings that resemble flat rings or disks where the rollers are perpendicular to the bearing bore axis. When multiple bearings are required, it could be advantageous to use two- or more single-row tapered bearings rather than multi-row bearings within a single housing. One such example is if one bearing will need to be maintained, adjusted, or replaced separately from the other. Another is when there is a need to allow for flexibility in design and add or subtract individual single-row tapered bearings, which is impossible with a multi-row tapered bearing.
