Deep groove ball bearings mainly bear radial loads and can also withstand both radial and axial loads simultaneously. When it only bears radial loads, the contact angle is zero. When deep groove ball bearings have a large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small, and the maximum speed is also high. Deep groove ball bearings have a simple structure and are easy to achieve high manufacturing accuracy compared to other types, making them easy to produce in series and in large quantities. They also have low manufacturing costs and are widely used. In addition to the basic type, deep groove ball bearings also have various variant structures,

The type code for single row deep groove ball bearings is 6, and the code for double row deep groove ball bearings is 4. Its structure is simple, easy to use, and it is a type of bearing that is widely produced and applied.

tolerance

The standard deep groove ball bearing has a common grade and all comply with GB307.1.

Clearance

The standard deep groove ball bearing has internal clearances of C2, CN, C3, C4, and C5 levels, all of which comply with GB4604.

Holder

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

Deep groove ball suffix meaning

CN: radial clearance of ordinary group; Usually used only in combination with the following letters to represent narrow or offset clearance ranges

H: The narrowed clearance range is equivalent to the upper half of the original clearance range

L: The narrowed clearance range is equivalent to the lower half of the original clearance range

P: The offset clearance range is equivalent to the composition of the upper half of the original clearance range and the lower half of the next set of clearance range

The above letters are applicable to the corresponding meanings of the following clearance groups: C2, C3, C4, and C5, such as C2
