Separation type bearings, bearings, have tapered raceway, roller is truncated. Roller and raceway for the line of contact, can bear high precision bearings radial and axial loads heavier, can also be subject to pure axial load. The larger the contact angle, the higher the axial bearing capacity. Contact line design of tapered roller should make the roller and the inner and the outer raceway extended to the thin section bearing axis at the same point, in order to realize pure rolling. Tapered roller bearing the new design with the reinforced structure, roller diameter increases, the roller length, roller number increase, Flange Slewing Bearing the convex roller, so that the bearing capacity and the fatigue life of bearing significantly improve. Spherical and conical surface contact between the roller large end face and large rib, improve the lubrication.
This kind of bearing according to the number of columns of the roller can be divided into single row, double row and four row tapered roller bearings of different structure types. This type of bearing is also used Inch series products.
