Single row deep groove ball bearings are the most widely used roller bearing type in the world due to their versatility and overall performance. They are characterized by having deep raceway grooves in which the inner and outer rings have circular arcs of slightly larger radius than that of the balls. They also have non-separable rings. Their straight forward basic design has many advantanges:
As flexible as the performance is, the configurations of single row ball bearnigs is also as versatile. These bearings often have steel shields or rubber seals installed on one or both sides and are pre-lubricated with grease. Also, snap rings are sometimes used on the outside edge. While many different retainers are available, pressed steel cages are most commonly used. Even tapered bores are available upon special order.
Materials
The performance and reliability of rolling bearings are greatly affected by the materials which the bearing components are made from.BXY bearing rings and balls are made of high quality of GCr15 vacuum-degassed bearing steel.Chemical composition of GCr15 bearing steel is basically equivalent to some representative bearing steel as the chart shown below.

Most of ball bearing cages are made of cold rolled steel sheet.Anf for some bearing types and special applications,cages are made of glass fiber reinforced nylon 66 plastic,phenolic or machined brass.
The material of bearing housings is gray or ductile cas iron, housings can also be made of pressed steel,stainless steel, or engineering plastics for special purposes.
Bearing Construction
· Bearing Ring - Contains inner and outer rings.Made of high quality steel, it can prolong the service life of bearing efficiently
· Rolling Element - Transfer the load between the inner and outer rings
· Retainer - Reduce friction heat, optimize load, and easy to disassemble
· Integral Seal - Greatly extend the service life of the bearing, keep lubricant in the bearing and keep contaminants out.
Bearing Parameters
Single row deep groove ball bearings come in three numerical series representing the size and load capacity of each. They are:
6000 Series - Extra Light Ball Bearings - Ideal for limited space applications
6200 Series - Light Series Ball Bearings - Balanced between space and load capacity
6300 Series - Medium Series Ball Bearings - Ideal for heavier load capacity applications
The parameters of 6200 series are as follows:
