Spherical roller bearing
Spherical roller bearings are in the two raceways and the inner ring raceway spherical outer ring between the assembly of drum-shaped roller bearings.
Spherical roller bearings with two rows of rollers, the main radial load, but also can withstand any direction of axial load. High radial load capacity, especially for heavy load or vibration load work, but can not afford pure axial load. This type of bearing outer ring raceway is spherical, so its aligning performance is good, can compensate the coaxial error.
structure type
Spherical roller bearings are divided into: cylindrical bore, conical bore.
Conical taper inner bore taper 1:12 respectively after the code-named K spherical roller bearings (153000 or 113000 type) and 1:30 after the code-named K30 spherical roller bearings. Such a cone with a conical shaft when the inner ring along the axial movement can adjust the bearing radial clearance.
