HBB High Performance Double Rows Cylindrical Roller BearingDouble Rows Cylindrical Roller Bearings have 2 structures with cylindrical and tapered holes(Postpositive Code: K): NNU designing and NN designing.
NN Types design that inner race has double ribs but outer race has no rib, while NNU Types design that the inner race has no rib but outer race has double ribs. Structure of tapered holes can adjust radial clearance while installing.
Double Rows Cylindrical Roller Bearings allow some specific axial displacement between shaft and bearing seat and thus can be used as non-positional bearings. These kinds of bearings have advantages like compact structure, large rigidity, large loads and small deformation and widely used for machine tools' main shaft.
