Deep Groove Ball Bearings

Deep groove ball bearings are the most widely used bearing types, especially with a variety of functions. This bearing has a low friction characteristic and can be optimized to reduce noise and vibration, thus achieving high speed. It can withstand radial loads and axial loads in both directions, is easy to install, and requires less maintenance than other types of bearings.

Product type, design and form

Single row deep groove ball bearings

The structure of a single-row deep groove ball bearing is relatively simple, and its rolling element (ball) and cage have deep grooves only on one side. This structure enables the single-row ball bearing to have lower friction and heat generation when running at high speed, so it is particularly suitable for low-load, high-speed running occasions.

Double row deep groove ball bearings

Double row deep groove ball bearings have deep grooves and rolling elements on both sides, so they have stronger load-bearing capacity. This structure enables double row ball bearings to withstand higher radial loads and is suitable for low or medium speed operation and high load occasions.
