NSK 395A/394A 395s/394A 399A/394A Inch Tapered Roller Bearing Rolamientos

Tapered roller bearings refer to radial thrust rolling bearings whose rolling elements are tapered rollers. There are two kinds of small cone angle and large cone angles. The small cone angle mainly bears the combined radial and axial loads dominated by radial loads. It is often used in pairs and installed in reverse. The inner and outer races can be installed separately, and the radial and axial clearances can be adjusted during installation and use; The large cone angle mainly bears the combined axial and radial loads, which are mainly axial loads. Generally, it is not used to bear pure axial loads alone but can be used to bear pure radial loads when arranged in pairs (the ends with the same name are installed opposite to each other).

Tapered roller bearings are separable bearings, and both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single-row, double-row, and four-row tapered roller bearings according to the number of rows of rollers installed. Single-row tapered roller bearings can bear radial loads and axial loads in one direction. When the bearing is subjected to radial load, an axial component force will be generated, so another bearing that can withstand the axial force in the opposite direction is needed to balance it.
