Reasons to choose Guomai Bearings as your Chinese cylindrical roller/rolling bearings 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.

Characteristics of cylindrical roller/rolling bearing

1. The contact of rollers and raceway belongs to linear type, hence enables the cylindrical bearing to withstand high radial load and makes it suitable for heavy and impact load.
2. Low friction advantage makes it suitable for high speed application as its speed limit reach close to the deep groove ball bearing.
3. N and Nu series of cylindrical roller bearings could move in axial direction, to accommodate potion changes of axle caused by thermal expansion and/or assembly deviation.  
4. Separable structure makes it easy for assembly, dis-assembly and maintenance.
