Guomai has large stock for normally used bearing models and this enables us to deliver the bearing to customers within the shortest time.
There are total 160 staffs, 6 automatic bearing assembly lines,116 CNC machines and 22 sets of precise inspection instruments. We not only have our own R&D team but also cooperate with Henan University of Science and Technology, Luoyang Bearing Research Institute to develop new bearing designing and manufacturing technology.
In addition to conventional bearings, Guomai also provides OEM and OM service to our respectable customers to meet their individual requirements.We introduced advanced milling, turning machines, heat treatment equipment and bearing testing machines to guarantee the quality of the bearings because we know "Quality is the life of Guomai" .Now our top products include taper roller bearing, angular contact ball bearing, deep groove bearing ,spherical bearing and cylindrical roller bearing with P5, P4 accuracy grade.
After so many years of developing, Guomai has built up an excellent sales network within China. Our two bearing brands "CVZ" and "Bentu" are well known and have high reputation within the industrial equipment and components field. Moreover, with confidence of our bearing quality, we started to export our bearings 4 years ago. Customers from Europe, North America, Middle East, Southeast Asia and Africa have enjoyed the happiness our bearings brought to them.
Guomai Bearing always upholds "WIN-WIN" spirit and believes in "Details determine success" philosophy, and keep improving bearing quality in the past 20 years.

Reasons to choose Guomai Bearings as your Deep Groove Ball Bearing 6303/6001/6201/6301/6004 partner
1. Bearing designing: Guomai has our own bearing R&D team and adopts Germany technology. This enables us to provide OEM and ODM service to you.2. Production process: We strictly follow the 5S production process and acquired ISO9001:2008 quality management system certificate. Besides, we introduced from abroad world famous brands lathes and heat treatment equipment, this enables us to provide high precision bearings with similar quality to world famous brands such as SKF,TIMKEN,NSK,NTN,KOYO,NACHI and so on.
3. Materials: To ensure the high quality of bearings, we use high carbon chrome bearing steel which provides high rigidity, and high resistance to abrasive wear to produce the bearings. Low carbon cold rolled steel and low carbon stainless steel is also used according to customers' requirements.
4. Quality inspection: All bearings will be strictly tested before packing. We have Taylor talysurf, hardness meter,clearance detector,vibration(speed) measuring instrument,roundness instrument to guarantee all bearings are qualified with the standards.
5. Lubricants: Suitable lubricants are used to protect the bearings from oxidation or corrosion of parts thus enable our bearings with longer lifetime, low noise and better high temperature performance. Selection of lubricants is generally governed by the bearing application. Right choice of high quality lubricants could prevent metal to metal contact and conduct heat away from the bearings.
6. Packing: Guomai bearings pay attention to every detail in the bearing production process. We adopt plastic bag, Kraft paper, thick paper box and cartons to protect the bearings from unexpectable damage during the transportation and warehouse stock.
7. Factory direct marketing: We are the factory and not the distributor or trading agent, so we could provide the same quality with competitive price.
