Design features: spherical roller bearings are self-aligning function, but is
also very strong. Spherical Roller Bearings are two rows of
rollers, in the outer ring, there is a sharing of spherical roller
Road, there are two Inner Raceway, with the bearing axial tilt into
a relative perspective. This is the bearing attractive design
features, in many demanding applications can not be replaced. KMR
spherical roller bearings are open, sealed and applied to the
specific application of bearings.
We can produce the diameter from 20mm~1 800mm KMR spherical
roller bearings. 25mm~220mm KMR sealed spherical roller bearings
etc. Following is the internal structure of KMR different product
descriptions.
