NSK Tapered roller bearings are separated type bearings. Both inner and outer rings of the bearings have tapered raceways, and the roller is round. The roller is in line contact with the raceway and can bear heavy combined radial and axial loads as well as pure axial loads. The larger the contact angle, the higher the axial bearing capacity.
Characteristics of NSK tapered roller bearings
The tapered roller should be designed so that the contact line between the roller and the inner and outer raceways is extended and intersected at the same point on the axis of the bearing to achieve pure rolling.
The newly designed tapered roller bearing adopts the reinforced structure, the roller diameter increases, the roller length lengthens, the number of rollers increases, and the roller with crown is adopted, so that the bearing bearing capacity and fatigue life are significantly improved. The contact between the large surface of the roller and the big edge is spherical and conical, which improves lubrication.Buy NSK tapered roller bearings NSK HR32218J
This kind of bearing can be divided into single row, double row and four row tapered roller bearings according to the number of rows installed. This type of bearings also use more British series products.
Structural characteristics of NSK tapered roller bearings
The type of tapered roller bearings is 30000, tapered roller bearings are separable bearings. In general, especially in GB / T307.1-94 "Rolling Bearing Centroid Bearing Tolerance" refers to the size range of tapered roller bearings between the outer ring and the inner assembly is 100% interchangeable. The angle of the outer ring and the diameter of the outer raceway have been standardized to the same size as the outer raceway. It is not allowed to be changed during design and manufacture. The outer ring and inner components of the tapered roller bearing can be exchanged all over the world.
NSK Tapered roller bearings are mainly used to withstand combined radial and axial loads with radial loads. Compared with angular contact ball bearings, tapered roller bearings have higher bearing capacity and lower limit speed. Tapered roller bearings can withstand axial loads in one direction and can limit axial displacement in one direction of the shaft or housing.Need NSK tapered roller bearings ,click here
