- Spherical Roller Bearings: Spherical roller bearings are designed to primarily support heavy radial loads and moderate axial loads. Their unique design includes barrel-shaped rollers guided by inner and outer ring raceways with a common spherical raceway on the outer ring, allowing them to accommodate misalignment and axial displacement. They are commonly used in applications where heavy radial loads, shock loads, and misalignment are present, such as in heavy machinery, mining equipment, and industrial applications.

A deep groove in a ball bearing refers to the specific design feature of the bearing's inner and outer raceways, which allows it to accommodate radial and axial loads while enabling smooth and efficient rotation. The deep groove is a critical aspect of the ball bearing's construction and contributes to its performance in various applications.
