Spherical roller bearings offer an unequaled combination of high load capacity, high tolerance to shock loads, and self-aligning ability, but they are speed limited. Duplex bearings and spherical roller thrust bearings should only be considered where axial loads predominate. C3 means the bearing has more clearance than standard.

A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers.

In the installation of a self-aligning roller bearing with fixed ends at both ends of a shaft, axial clearance shall be set aside between the end cover of both ends of the shaft and the end face of the bearing outer ring, and the outer diameter of both ends of the bearing and the seat hole shall be fitted with small clearance.

The contact surface is the curved portion of a sphere and the curvature allows the carrying of axial loads. The axial load carrying capacity is less than that 

For high-load and high-speed spherical roller bearing installation, when adjusting the clearance, the influence of temperature rise on the axial clearance must be considered, and the amount of clearance caused by temperature rise is estimated, that is, axial travel. The gap should be adjusted to a larger size.

SKF bearing internal clearance is defined as the total distance through which one bearing ring can be moved relative to the other in the radial direction (radial internal clearance) or in the axial direction (axial internal clearance). In almost all applications, the initial clearance in a SKF bearing is greater than its operating clearance.

For high-load and high-speed spherical roller bearings, when adjusting the clearance, the influence of temperature rise on the axial clearance must be considered, and the amount of clearance reduction caused by temperature rise should be estimated. That is to say, the axial clearance should be adjusted to be a little larger.

Radial internal clearance adjustment is one of the most overlooked areas in the installation process of spherical roller bearings, but in reality it is one of the most important factors that affect bearing performance. So to get a better understanding of how much is needed, we need to understand what it is first.

Spherical roller bearings Spherical roller bearings have two rows of symmetrical rollers, a common sphered outer ring raceway and two inner ring race - ways inclined at an angle to the

Bearing internal clearance for spherical plain bearings is defined as the total distance through which one ring can be moved radially (radial internal clearance) or axially (axial internal clearance) in relation to the other ring under a defined measuring load. It is necessary to distinguish between the internal clearance of a spherical plain
