Custom Bearing Manufacturing

AUB has over 20 years of experience in custom bearing manufacturing solutions and a solid understanding of industry specific requirements. To name a few, we serve customers in the automotive industry, agriculture, forestry, medical, mining, railways, wind power and – for every application, from the smallest equipment to the largest machines. In our 8000 square meter factory, automated manufacturing lines and years of knowledge reserves of 160 engineers, we can provide you with all the bearings you need.

At AUB Bearing, we are known for our bearings manufactured using 52100/ GCr15 bearing grade steel, a chromium containing high carbon alloy material that offers excellent strength, wear and fatigue properties. Custom chrome steel bearings have a higher dynamic load capacity than 440C stainless steel bearings and are significantly less expensive than bearings made from tool steel materials. We also produce several other steels, stainless steels, ceramics and plastics for corrosive environment applications such as the pool and spa industry, medical devices, health and beauty appliances (HBA), and the semiconductor industry. In addition, we also offer bearings made of selected engineering plastics.

Custom Bearing Manufacturing Solutions

AUB Bearing can custom design your special bearings to solve operating environment issues, extend service time, improve equipment performance, and even save energy. The housing it needs to fit in, the tasks it needs to perform, the weight it needs, AUB custom bearing experts will design a solution to achieve all of these goals quickly and at a competitive cost.

Custom Bearing Manufacturing Services

If customer have the drawing, which includes the dimensions, materials, special requirements, then we can make the mold according to the drawing.

If customer have no drawing, we can design according to customer request, to make a drawing and get confirmation from customer. Then we make a mold according to the drawing.

We will prepare Mould to make shipments, and send samples for customer approval before shipments

After test the mold, if the mold is ok. Then make the samples, our engineer will measure the After samples confirmed, we will make documents and book vessel to ship to customer , sometime if urgent by air.

The production flow as bellow:

Raw Material booking → Raw material testing → turning process → heat treatment → grinding process → products inspection → super grinding process → bearing rings cleaning process → Bearing assembly → Bearing cleaning → bearing greasing/sealing process → quality inspection → logo marked–package .

Then we will ship our goods, small quantity, usually by express transport , such as FedEx , DHL, TNT, UPS, or by air. If large quantity, usually by ship or land transport ,or by air .
