Leading China roller bearing manufacturer introduce with people the classification of their Tapered roller bearing

China - The majority of clients of NINGBO RUNNING BEARINGS CO., LTD which is the leading China roller bearing manufacturer have generally problem which refers to the main classification of their Tapered roller bearing. Today, the specialized engineer from this bearing manufacturer specifically writes this release to let their consumers have fully knowing about the classification.

The first type is the single row Tapered roller bearing . Typically, the cone angle of the outer ring raceway for this type of single row roller bearing is at 10 degrees to 19 degrees, which could help the roller bearing withstand the combined effects of axial and radial loading. The larger the cone angle, the better the axial loading capacity of the bearing. The code B is the representative of the roller bearing with the large cone angle which is between 25 degrees to 29 degrees. This kind of bearing could withstand the unimaginable high axial loads. In addition, the clearance of single row tapered roller bearing can be resized during the installation process.

The second type is the double row tapered roller bearing which the outer and inner ring is a whole unit. The end of two inner rings or outer rings is very close and there are also the special spacers between them. The clearance of this kind of roller bearing could be changed by adjusting the thickness of the spacer.

The third sort is the four-row Needle Roller Bearing which performance is basically the same with the double row bearing, However, this load withstanding of this kind of roller bearing is bigger than that of the double row tapered roller bearings but the max speed limitation of this bearing is lower than former one. This roller bearing could be mainly used for the operation of heavy machinery such as rolling machines, mining machines and crushers.

The NINGBO RUNNING BEARINGS also provide with clients the Multi-sealed double rows and four-row tapered roller bearings. For this type of roller bearing, the designers of this company apply the personalized new design to replace the traditional designation of the fully sealed bearing. The using of the new type of sealing and anti-dust sealing structure could largely improve the sealing effect and performance. Compared with the normal opening structure roller bearing, the Multi-sealed double and four-row tapered roller bearings could enjoy the advantage of 20% to 40% service life increasing and 80% reducing of the lubricated oil consumption. That should be the good news for the roller bearing purchaser.
