Deep groove ball bearing

Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When it is only subjected to radial loads, the contact angle is zero. When a deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can withstand a large axial load. The deep groove ball bearing has a small friction coefficient and a high limit speed. Deep groove ball bearings have a simple structure and are easy to achieve higher manufacturing accuracy than other types, so they are convenient for mass production in series, the manufacturing cost is low, and they are extremely common. In addition to the basic type, deep groove ball bearings also have various modified structures. The single-row deep groove ball bearing type code is 6 and the double-row deep groove ball bearing code is 4. Its structure is simple and easy to use. It is a type of bearing that is more common in production and widely used.

    Tolerance

    Standard deep groove ball bearings have ordinary grades, all conforming to GB307.1.

    Play

    Standard deep groove ball bearings have C2, standard (CN), C3, C4, and C5 internal clearances, all in accordance with GB4604.

    Cage

    Deep groove ball bearings generally use steel stamped cages or brass solid cages. When the outer diameter is less than 400 mm, a steel stamped cage is used without a post code. When the outer diameter is greater than 400 mm, a brass solid cage is often used without a post code.
