Do you know high precision spherical roller bearings’ function?

601 Published by Sep 12,2018

High precision spherical roller bearings

The high precision spherical roller bearings have two rows of rollers, a common spherical outer ring raceway and inner ring raceway inclined at an angle to the bearing axis. The center point of the sphere in the raceway of the outer ring is at the bearing axis. Thus, high precision spherical roller bearings, self-aligning and insensitive shafts relative to the housing, which can, for example, cause misalignment caused by deflection of the shaft. Spherical roller bearings are designed to withstand heavy radial loads and axial loads in both directions.

The performance of the high precision spherical roller bearings depends not only on the load or speed grade. There are many other factors that contribute to the performance of the bearing. To a large extent, the performance affects the geometry of the rollers, the raceways and cages, the heat treatment, and the surface finish of all contact surfaces. High acoustic spherical roller bearings are the main influencing factors of performance, including, but not limited to:
Symmetrical roller
Self-adjusting of the symmetrical rollers provides optimum load distribution along the roller length. This makes it possible to extend the life of the bearing under all load conditions.
High precision spherical roller bearings
High precision spherical roller bearings are manufactured with extremely tight tolerance dimensions and forms. The other rolls in each set are almost the same size and shape. Optimize the life of the load distribution roller bearing to maximize.

Roll profile

The roll profile determines the stress distribution at the roller/raceway contact area. Special shape distributes the load evenly along the drum and prevents stress peaks at both ends of the roller, prolonging the life of high precision spherical roller bearings
Two-row roller

Self-guided, the rollers reduce friction and frictional heat. A floating guide ring guides the unloading rollers, allowing them to enter the optimal position of the load zone.
