Description for Inch Taper/Tapered Roller/Rolling Bearing
Inch taper/tapered roller bearings belong to separable bearing, as the outer ring, also called cup, is separable and easy for assembly. Both the inner ring(cone) and the outer ring(cup) have tapered raceways which allow the tapered rollers run smoothly within the rings.
This design enables the bearing to withstand mainly the radial load but also combined with the single-direction axial load. According to the structure designing forms, inch tapered roller bearings could be divided into single row, double rows and four-row taper rolling bearings. Double row inch taper roller bearings increased the radial work load capability.
Inch tapered roller bearings have a wide range of application fields such as automobile parts,metallurgical machinery,mining machinery,plastics machinery,mining machinery etc..

Reasons to Choose Us ?
-------Why Choose Us-------
Reasons to choose Guomai Bearings as your inch taper/tapered roller/rolling bearing 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.
