- Cylindrical Roller Bearings: Cylindrical roller bearings consist of cylindrical rollers that are guided by inner and outer ring raceways. They are designed to support high radial loads and moderate axial loads and are commonly used in applications where precise radial load support is essential.

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.
