Installation Method of Spherical Roller Bearing

The CA series and CC series of spherical roller bearings produced by FV should be installed according to different application  conditions, so that different installation steps should be taken. If it is a self-aligning bearing, during the installation process, the middle mounting ring should be used when the bearing with the shaft is inserted into the box shaft hole, which can prevent the outer ring from tilting and rotating. It should be noted that the balls of some sizes of self-aligning ball bearings protrude from the side of the bearing, so the middle mounting ring should be recessed to prevent damage to the balls.

Spherical roller bearings are equipped with drum-shaped roller bearings between the inner ring with two raceways and the outer ring with spherical raceways. The curvature center of the outer ring raceway surface is consistent with the bearing center, so it has the same centering function as the self-aligning ball bearing. When the shaft and housing are deflected, it can automatically adjust the load and the axial load in two directions. Large radial load capacity, suitable for heavy load and shock load. Bearings whose inner diameter is a tapered bore can be directly installed. Or use an adapter sleeve or a disassembly tube to install it on the cylindrical shaft. The cage uses steel stamping cage, polyamide forming cage and copper alloy car cage. A large number of bearings are generally installed by mechanical or hydraulic press-in method.

FV's spherical roller bearings, when installing and adjusting the axial clearance, can be adjusted by adjusting the nut on the journal, adjusting washer and the thread in the bearing seat hole, or using a pre-tensioned spring. The size of the axial clearance is related to the arrangement of the bearing, the distance between the bearings, and the material of the shaft and the bearing seat, and can be determined according to the working conditions.
