The design of a cylindrical roller bearing allows it to accommodate high radial loads, making it suitable for applications such as machine tool spindles, gearboxes, electric motors, and industrial equipment. The cylindrical shape of the rollers enables them to distribute the load over a larger surface area, reducing stress and preventing premature wear.

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.

The function of a single row deep groove ball bearing is to provide support for radial and axial loads, reduce friction, facilitate smooth and efficient rotation, and maintain the integrity and performance of mechanical systems. Here are the key functions of a single row deep groove ball bearing:
