Product Description

Deep Groove Ball Bearing

Deep groove ball bearing (GB/T 276-2003), formerly known as single row radial ball bearing, is the most widely used type of rolling bearing.

Its characteristics are low frictional resistance, high rotational speed, and can be used on components that can withstand radial loads or combined loads acting both radially and axially. It can also be used on components that can withstand axial loads, such as low-power electric motors, automotive and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.
The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a retaining structure. There are two types of deep groove ball bearings: single row and double row. The deep groove ball structure is also divided into sealed and open structures. Open refers to the bearing without a sealed structure, while sealed deep groove balls are divided into dustproof seals and oil proof seals. The material of the dustproof sealing cover is steel plate stamping, which only plays a simple role in preventing dust from entering the bearing raceway. The oil proof type is a contact oil seal, which can effectively prevent the leakage of lubricating grease inside the bearing.
