BEARING 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:

BEARING PACKING
Our packaging is also very variable, the purpose is to meet the needs of different customers.The commonly used packages are as follows:
1.Industrial package+outer carton+pallets
2.Single box+outer carton+pallets
3.Tube package+middle box+outer carton+pallets
4.According to your requirements
BEARING INSTRUCTIONS
The bearings are coated with antirust agent and then packed and leave the factory.It can last for years if properly stored and well packed.Bearing storage should be noted as follows:
1. Keep in a place with a relative temperature below 60%;
2. Do not directly placed on the ground, at least 20 cm from the ground on the platform placed well;
3. Pay attention to the height when stacking, and the stacking height should not exceed 1 meter.
