Miniature Self Aligning Spherical Roller Bearing 45-55mm Inner Diameter
Description,
Spherical roller bearing has two columns of roller, mainly endure radial load and also withstand any direction
of axial load at the same time. This kind of bearing own a high capacity of radial load especially suitable for
heavy load or vibration, but can’t bear pure axial load , The outer ring groove of this bearing is spherical, so
it's favorable in regulating the heart. Spherical roller bearings and self-aligning ball bearing are the same at
the structure theory and character, so they can substitute each other in the permission of load capacity and
speed limit.
