Details
Spherical roller bearings are designed to accommodate heavy radial and axial loads while allowing for misalignment between the shaft and housing. The design of spherical roller bearings enables them to handle dynamic and shock loads effectively, making them suitable for applications with heavy loads, shaft deflections, or misalignment. Suffix E features an optimized internal design with large symmetrical rollers and a pressed steel cage.
