Deep groove ball bearing

Deep groove ball bearings are mainly subjected to radial loads and can also withstand radial loads and axial loads. When it is only subjected to radial loads, the contact angle is zero. When the 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. The deep groove ball bearing has a simple structure and is easy to achieve high manufacturing precision compared with other types, so it is easy to be mass-produced in series, and the manufacturing cost is also low, and the use is 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.
