deep groove ball bearings


Deep groove ball bearings are the most common type among ball bearings. The basic type deep groove ball bearing is composed of an outer ring, an inner ring, a set of steel balls and a set of cages. Deep groove ball bearings have single row or double rows, sealed-type or open-type. The open-type ones are without leakproof structure. The sealed-type ones are divided into dust seal and oil seal. The material of dust seal is stamping steal, simply preventing dust from entering the raceway. Oil seal is contact seal, which can effectively prevent the grease from overflow.
Deep groove ball bearings are the most representative ball bearings with wide application. They can be used under high speed and even extremely high speed, very durable, without regular maintenance. They have small friction coefficient, high speed, simpe structure, low cost, and are easy to achieve high manufacturing precision. Their size and modes are diverse so they're used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries. These bearings are most widely used in machinery industries. They mainly sustain radial load, and also can sustain some axial load.
