Deep groove ball bearings
Deep groove ball bearings are one of the most common types of rolling bearings. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cage. Its structure is simple, easy to use, is the most common production, the most widely used type of bearing.
Structure and characteristics
Deep groove ball bearings belong to the non-separable type of bearings, its structure is simple, the use of extremely common. Deep groove ball bearings in addition to the basic type, there are a variety of variants of the structure, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber seals, deep groove ball bearings with stopping grooves, there is a loading gap of the large load capacity of full complement deep groove ball bearings.
Deep groove ball bearings are mainly used to bear radial loads, but they can also bear radial loads and axial loads at the same time. Suitable for use in high-speed operation under working conditions. When it only bear radial load, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, has the performance of angular contact bearing, can withstand larger axial load. The coefficient of friction of deep groove ball bearings is very small, and the limiting speed is also very high, but it is not suitable for bearing heavy loads. Select a larger radial clearance when the axial load carrying capacity increases, bear pure radial force when the contact angle is zero. When there is axial force, the contact angle is greater than zero.
