Product Description

Product Description

 

Characteristics of Hub bearings

The main function of the hub bearing is to bear the weight and provide precise guidance for the rotation of the hub. It bears both axial load and radial load and is a very important component.

We can produce a wide range of products including but not limited to: , , , and more, catering to different industries and applications.

In strict accordance with the ISO 9001: 2015 quality management system requirements in the production process,Products obtained the EU "CE' certification

At present,We have got oversea customers from Spain,Germany,India,Russia,theUnited States,Pakistan,South Africa and other countries.

Product Highlights

In terms of raw materials:

we use excellent bearing steel from Jiangyin Xingcheng Special Steel. It has high and uniform hardness and wear resistance, a high elastic limit, excellent thermal conductivity, good fatigue life, and good corrosion resistance. These superior properties in our raw material selection set us far above other manufacturers.
 

Heat Treatment:

We have a professional heat treatment production line. After heat treatment, our bearing components are sufficiently hardened to withstand fatigue and plastic deformation, have enough strength to bear external loads, and have sufficient stability to keep dimensional changes over time within a limited range.

 

 

turning

In the entire bearing manufacturing process, turning operations are influenced by the quality of the preceding forging process and provide reliable assurance for the machining quality and efficiency of subsequent operations. Inaccurate dimensions, irregular shapes, and deep oxidation layers in the raw forging can lead to low material utilization rates and reduced turning efficiency, ultimately increasing production costs.
We have made significant improvements and enhancements to our existing turning processes, ensuring not only the original processing efficiency but also significantly reducing costs.

Grinding processing

We use a strict inspection system in the bearing grinding process, which effectively improves the accuracy and dimensional consistency of bearing parts, improves the surface roughness and flatness of bearing parts, thereby improving friction characteristics and service life, and ensuring that the assembled bearings run smoothly, with low noise and low vibration.

Detection system

We have a complete testing system, from metallographic testing of raw materials to dimensional control of grinding, each process has a demanding testing plan. We also have a system that can trace the test data. We can achieve traceability for each model and each specification to facilitate future customer needs.

Q: What precautionary measures I should adopt before installation of bearings?
A: Firstly, doesn't need to remove the preservative coating of the bearings. It is necessary to wipe off the outside cylindrical surface and bore, if the grease is not compatible with the preservative then wash and carefully dry the bearing. Bearings should be installed in a dry, dust-free room away from metal working or other machines producing swarf and dust.
