Product Description

Product Description

Features
Simple internal structure, low friction and high limiting speed, mainly bear radial direction load. Deep groove ball bearing can obtain angular contact capability when increasing radial clearance, to take combined load of both axial and radial directions. When the thrust ball bearing is not appropriate for some high speed applications, deep groove ball bearing may be an alternative choice to afford axial loads.
 

 

Products' Advantages

Material

We usually use bearing steel (GCr15), but many manufacturers only use softer carbon steel materials, so our bearings have higher hardness and longer service life.

Heat treatment
We have our own heat treatment plant and do not need to be outsourced. We use a slower speed and more stable temperature to effectively control the steel and increase the toughness and life of the steel.
Other small-scale bearing companies usually need to outsource. Many outsourcing factories only strengthen the hardness of the bearing surface due to cost factors, but the hardness inside is not enough, which is the reason why many bad bearings are easy to crack.

Precision
Our bearings can be controlled at a height accuracy of 0~-0.004mm, fast speed and smoothness.

Multiple grinding process
We grind the bearing many times, but others may grind it only once, so the chamfer of our bearing is very smooth.

In conclusion
We use high-quality materials and multiple grinding processes, so our bearings have the characteristics of high speed, low noise, high precision and long life.
 

Application:
Deep groove ball bearings are widely used in automobiles, motorcycles, motor, electric tools, textile machinery,machine tools, construction equipment and transmission equipment, and other fields. 
They are also are widely used in household appliances and office equipment, such as refrigerators,air conditioners, washing machines, microwave ovens, lampblack machine, vacuum cleaners, sewing machines, massage chair and fitness equipment and other fields.
 

 

How to expand the lifetime?
1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.
2. Don't allow strong impact, such as hammer striking, transfer roller pressure
3.Use the accurate installation tool, avoid to use cloth kind and short fibers
4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer
5. General inspection, such as the surrounding temperature, vibrate, noise inspection
6. Keep bearing cleaning from dirt, dust, pollutant, moisture.
7. Bearing should not be ultra cooled.
